![]() The ability to handle both extremely low (cryogenic) temperatures and, depending on the load and permissible distortion, higher service temperatures of around 600 degrees Celsius or even higher if scaling resistance is the principal consideration.Ĭommon uses and applications cover an extremely wide scope such as hollowware, builders' hardware, architectural applications, abattoir, beer and beverage production and food processing equipment (which require cleanability and hygienic corrosion resistant properties).Usually used in the fully annealed condition in which they are essentially non-magnetic The most common austenitic stainless steel and most common of all stainless steel is Type 304, also known as 18/8 or A2.Since the materials austenitic structure is not. Type 304the most common grade the classic 18/8 (18 chromium, 8 nickel) stainless steel. Hardened by cold work, not by heat treatment SUS301 has a chromiumnickel ratio of 177, which is slightly lower than that of 188 stainless steel.It has a nominal composition of 18 chromium and 8 nickel. Excellent cleanability and hygienic properties Type 304 (frequently referred to as 18-8 stainless) is the most widely used alloy of the austenitic group.Austenitic grades are the most commonly used stainless steels accounting for more than 70% of production (304 is the most commonly specified grade by far).īasic properties of austenitic stainless steels include: The basic composition of austenitic stainless steels is 18% chromium (Cr) and 8% nickel (Ni). When nickel (Ni) is added to stainless steel in sufficient quantities, the crystal structure changes from ferrite to austenite, hence the term austenitic stainless steels.
