Crystalline structures of stainless steel
There are two subgroups of austenitic stainless steel. 300 series stainless steels achieve their austenitic structure primarily by a nickel addition while 200 series stainless steels substitute manganese and nitrogen for nickel, though there is still a small nickel content. 300 series stainless steels are the larger subgroup. The most common austenitic stainless steel and most common of all stainless steel is Type 304, also known as 18/8 or A2. Type 304 is exte… The austenitic grades (see Figure 4) are the largest group of stainless steels, and can be divided into five sub-groups: 1. Cr-Mn grades 2. Cr-Ni grades, 3. Cr-Ni-Mo grades 4. High performance austenitic grades 5. High temperature austenitic grades The austenitic grades have good to excellent corrosion resistance, … See more Martensitic grades are often used in applications where high strength and wear resistance is demanded, such as for shafts, knifes and for wear and press plates. See more Duplex grades (see Figure 5) have a ferritic-austenitic microstructure, with a phase balance of approximately 50% ferrite and 50% austenite. Duplex grades combine many of the … See more
