High cost especially at the initial expense.Environmentally friendly and recyclable. ![]() Can be given a particular finish if attractive cosmetic appearance is desired, and does not tarnish easily.Long lasting, with a relatively low cost over the course of its lifecycle.Precipitation, with the corrosion resistance of austenitic metals, but can be hardened to higher strengths, and so can be made to be extremely strong when other elements like aluminium, copper and niobium are added.Duplex, a composite of austenitic and ferritic steels, making it both strong and flexible, with twice the yield strength of austenitic stainless steel, used in the paper, pulp, shipbuilding, and petrochemical industries.Martensitic, which tends to be magnetic and less corrosion-resistant than other stainless steels due to its low chromium content – these matels are very hard and strong and are used to make knives and turbine blades.Ferritic, a form of steel generally with no nickel, often possessing better corrosion, heat, and cracking resistance than more common types, and frequently used in washing machines, boilers and indoor architecture.Austenitic, the most widely used type of stainless steel, with low yield strength but strong corrosion and heat resistance, commonly used in housewares, industrial piping and vessels, construction, and architectural facades – this is the largest family of stainless steel and makes up about two thirds of all stainless steel production.There are various types of stainless steel, which include: This allows it to resist corrosion or rust and makes it ‘stainless.’ Types of Stainless Steelĭifferent chromium levels of stainless steel will give it different properties, with a lower chromium content generally producing a cheaper but less durable steel. Stainless steel is therefore given a protective layer of chromium to create a barrier between environmental oxygen and the metal’s iron content. It is sometimes called inox steel as it is designed to protect against oxidisation and so is ‘inoxidable.’ When exposed to oxygen, iron oxidises, making it rust, however chromium can be exposed to oxygen without undergoing this process. Stainless steel refers to a type of steel which is defined by the addition of chromium, and some other alloying elements such as nickel. These differences give each type of steel its respective properties. ![]() Carbon steel tends to have under 10.5% chromium content, but steel must be at least 10.5% chromium to be considered stainless. Though they have the same basic composition of iron and carbon, steel types tend to have a variety of alloying elements. There are many grades but most types of steel fall into two broad categories, carbon steels and stainless steels. ![]() Steel, a term that actually describes an entire family of metal alloys, is a versatile and common type of metal with a wide variety of applications and uses.
