Black Steel & Bright Drawn Steel

Black steel is produced by rolling the steel at a high temperature (typically over 1700° F), as it needs to be hotter than steel’s recrystallization temperature. When it is above the recrystallization temperature it can be formed and shaped more easily. It can also be made in much larger sizes. Black steel tends to be cheaper than bright drawn steel due to the fact that it can be manufactured without any delays in the process. However, when the steel cools down it shrinks slightly, which results in less control on the shape and size of the finished product compared to bright drawn steel. It can have a scaly, rough surface and is not precise in its dimensions, flatness or straightness. More..

PVD Stainless Steel

PVD is the abbreviation for Physical Vapour Deposition. It is a process which produces a metal vapour (chromium, titanium, and titanium aluminium) that can be deposited on electrically conductive materials as a thin, highly adhered pure metal or alloy coating. The PVD process In the PVD process, a solid metal such as titanium, is atomised into minute molecules using electricity in a vacuum chamber containing a high purity gas such as argon, nitrogen or oxygen. The metal reacts with the gas and condenses on the sheet material or component suspended in the chamber. Different gas and metal combinations create different colours. Why use PVD coatings? • PVD coating is harder and more corrosion resistant than the coating applied by the electroplating process • PVD coatings do not tarnish or discolour. • They have reasonably high corrosion resistance and doesn't suffer UV radiation so easy. • PVD coatings are more environmentally friendly than traditional coating processes such as painting or electroplating • It gives a low friction film for protection • PVD coating can be used on various materials, including aluminium, iron, porcelain, stainless steel and some types of PVC. Stainless steel is the material most recommended for PVD coating and can result in a wide range of colours, surface patterns and finishes. Stainless steel will normally fade and oxidize over time when exposed to the environment. • Benefits of PVD coating • Once it has been PVD coated, it: • • Will be not so prone to oxidize, tarnish or discolour in harsh sun, humid environments or salt water • Will be impervious to extended UV light exposure with no cracking, flaking or discolouration • • Applications • There is widespread use of PVD coloured stainless steel in the architectural and industrial design industry, such as for stainless steel curtain walls, cladding and profiles on buildings including casinos, hotels, shopping centres, railway stations, airports and high-end retail stores. It is also used for products including fuel injection systems, injection moulding tools and plumbing fixtures.At the smaller end of the scale, PVD coated materials can be used for anything from lighting fixtures, display cases and furniture, to handles, door furniture and taps. The PVD process can also be used on metal jewellery, achieving stunning colours. More..

What is Galvanizing and why?

What is Galvanizing and why? Without protection, steel rusts due to atmospheric conditions and the degree of rust depends on the environment of the product. Galvanization is the process of applying a protective zinc coating to iron or steel in order to prevent rust and corrosion. The coating effectively becomes part of the steel as the zinc is bonded metallurgically to it. Cleaning Galvanizing can only occur if the steel’s surface is chemically clean. It is essential that it is free from dirt, grease and scale before the process can begin. The common practice is to degrease first then rinse in cold water to avoid contaminating the rest of the process. The steel is then dipped in hydrochloric acid to remove any rust and mill scale. After further rinsing, the components will then commonly undergo a fluxing procedure by dipping in a flux solution. This removes the last traces of oxide and allows the molten zinc to wet the steel. Galvanizing When clean iron or steel is dipped into molten zinc (usually at around 450°C) a series of zinc-iron alloy layers are formed by a metallurgical reaction between it and the zinc. The initial rate of reaction is very rapid and the main thickness of coating is formed during this period. Subsequently, the reaction slows down and the thickness of the coating is not increased significantly even if left in the bath for a longer period of time. The typical immersion time is about four or five minutes but it can be longer for heavy pieces that have high thermal inertia or where the zinc coating needs to penetrate internal spaces. Post Treatment Post galvanizing treatments can include air cooling or quenching in water. Conditions in the galvanizing plant such as air quality, temperature and humidity won’t affect the quality of the galvanized coating but are critically important for good quality painting. A paint or a powder coating can be applied for aesthetic reasons or for additional protection where the environment is extremely aggressive. Chemical coatings and other barrier systems might also be applied to minimise the occurrence of wet storage stain. Galvanizing is a versatile process and products ranging in size from nuts and bolts to long structural sections can be treated this way. It is both economical and environment. More..

Why recycle aluminium?

Producing aluminium from raw materials is an expensive and complex process. However, it has the ability to be melted down and reformed without losing any of its quality; its atomic structure is not altered during melting. In fact, aluminium can be recycled over and over again with 100 percent efficiency and only 5 percent of the energy used to make new aluminium is needed. In theory, there could be a time when we have mined all we need and can just keep re-using the aluminium we already have. Aluminium scrap has a high market value as the energy needed for primary production is stored in the metal itself and consequently, in the scrap too. More..

Ferrous and non-ferrous

Ferrous and non-ferrous The word ferrous is derived from the Latin word ferrum, meaning "iron". Quite simply, ferrous metals contain iron where as nonferrous do not. Ferrous metals can contain small amounts of other metals or elements to give the required properties. They are magnetic and do not have much resistance to corrosion. Non-ferrous metals do not contain iron, they are not magnetic and are generally more resistant to corrosion than ferrous metals. Ferrous Metals Ferrous metals are iron and steel, and their variants. They are strong, tough and easy to machine, but are prone to rusting and corrosion. • Mild Steel has a carbon content of between 0.1% and 0.3% and an iron content of 99.7% to 99.9%. It is used for engineering purposes and as the least expensive of all steel, it is the most common used. Mild steel is weldable, it’s very hard and very durable. • Carbon steel contains 0.6% to 1.4% carbon and 98.6% to 99.4 % iron. It is generally used to make industrial tools, machinery, drill bits and knives. • Stainless Steel is iron with varying additions of nickel, chromium and other metals depending on the grade and its end use. It is better defended against corrosion and used in thousands of applications. • Cast Iron contains between 2% and 6% carbon and 94% to 98% iron. It is very strong but at the same time, brittle. It is used to manufacture heavy items including engine blocks and manhole covers. • Wrought Iron is almost 100% iron. It is less popular than it once was but is still used for decorative items such as railings. • Ferrous metals are the most recycled materials in the world. In 2008 alone, 1.3 billion tons of steel were produced, 500 million tons of which was made from scrap materials • Non Ferrous Metals • Non-ferrous metals are many and diverse, and include rare and precious metals. They have wide range of mechanical properties and material characteristics resulting in a vast array of uses across all industries and commercial uses. • Aluminium is an alloy of aluminium, copper and manganese. It is very lightweight and can be easily worked, and available in a range of grades depending on end-use • Brass is a combination of copper and zinc. It is generally used for decorative purposes due to its resemblance to gold. • Copper is a naturally occurring metal. As it conducts heat and electricity, it is commonly used for wiring, tubing and pipe work. • Gold is most famously used for jewellery and as an investment in the form of bars or bullion. It is also used as an electrical connector, as a thread and even as food decoration. • Lead is a heavy and very soft metal which is often used in roofing and to make pipes. • Nickel is a silvery-white metal. It is often used as an alloying agent with other metals and historically was used to make cheap coins. • Silver is another natural substance, used mainly for decorative jewellery and ornaments. It is also used to solder different metals together. • About half of all Tin produced is for solder, when it is combined with lead. It is also used to plate other metals and as an alloy • Titanium is another silver-coloured metal and was discovered in Cornwall. It is another common ingredient as an alloy but it mostly used for refinement in to titanium dioxide; an intensely white pigment used in plastics, paints and toothpaste • Zinc is mostly used for galvanisation; applying a protective zinc coating to iron or steel to prevent rusting. It is also a common alloy. More..
