Stainless Steel – Introduction Stainless steel is not a single material but the name for an extensive range of corrosion resistant alloy steels. These alloys were rst developed early last century and by the 1920’s several types had been established. In the UK Harry Brearley developed a 13% chromium steel, whilst working on a steel to improve the wear characteristics of rie barrels. He observed that this steel only reacted slowly with his laboratory etching acids and when discarded sample pieces which were left outside in the rain did not rust, like lower chromium steel did. This “chromium/...

Stainless Steel – Introduction Types of Stainless Steel (Families) Corrosion Resistance Stainless steels have “family” names that reect their metallurgical (atomic) structure. All stainless steels are able to resist some level of corrosion. There is a wide range of service media and different forms that corrosion attack can take. This is one reason why there are the four main families of stainless steels and why each has its own range of grades. Stainless steels all rely on the chromium content to form a corrosion resisting, tightly adherent, chromium-rich passive layer. This invisible,...

Stainless Steel – Introduction around 60 HRC (Rockwell C). In contrast the precipitation hardening grades, despite their name, are mainly used for their heat treatable strength rather than hardness. l Toughness and ductility The properties of toughness and ductility usually go together, although they are different properties. Toughness is a measure of how much energy is absorbed by the metal during fracture. A brittle material has low toughness. Usually as temperatures get lower, the toughness of metals decreases. The austenitic stainless steels have excellent toughness, not only at ambient...

Stainless Steel – Introduction additions are made, austenitic grades having between 7-13% Ni and the more exotic grades up to 30%Ni. These nickel additions are also responsible for the change in the steels structure from ferritic to austenitic. Structurally, between the ferritic and austenitic family grades are the duplex steels, with typically 3.5-6.5% Ni. Most of their corrosion resistance is derived from their chromium, molybdenum and nitrogen contents. The main function of the nickel is to “balance” the structure, which provides enhanced strength and resistance to stress corrosion...
