Alloy & Stainless Steel

Stainless steels are a group of steels that contain at least 10.5% chromium. The addition of this element, along with a wide variety of others, especially Nickel and Molybdenum, generally improves corrosion resistance and mechanical properties at high temperatures making them suitable for a range of arduous applications.
All the main stainless steel types are stocked including duplex, super duplex, austenitic, martensitic, precipitation hardened, maraging and aerospace specifications. Stainless steel finds many applications where a hard material is required that will resist corrosive attack.
Alloy & Stainless Steels Applications
It might be easier to list the places where stainless steel is not used than to summarise all of the applications that take advantage of this most versatile steel. However because of its corrosion resistance and ability to take a high polish it is more prominent in certain areas.
- For instance in the home stainless steel can be found most commonly in the kitchen where it is manufactured into cutlery, cleaning and drying machine drums, sinks and more recently fridges, kettles and toasters.
- In our towns and cities stainless steel is used for bus shelters, telephone booths and other street furniture. Stainless steel building facades not only look good but also protect the underlying building structure. Subway trains and station infrastructure use stainless steel as it is tough, stain resistant and can be easily cleaned.
- Industrial applications include equipment for the manufacture of food products and pharmaceuticals where the stain resistance and easy cleaning properties are most desirable. The harsh environment in the chemical and petrochemical industry also make use of stainless steel for its resistance to corrosive liquids. Automotive and aero engines components are made from stainless steel where either good looks or high strength and toughness are required.
Stainless steel is also fully recyclable and even when the redundant or scrap parts are processed in the furnace the material is not downgraded and the steel retains its original quality. However since stainless steel has such a long life this contributes to resource minimisation so that new material is not needed so often to replace corroded or failed products.
