The most common US grades of stainless steel are: TYPE 304 Also known as "marine grade" stainless steel due to its increased resistance to chloride corrosion compared to type 304. Martensitic grades are magnetic in both the annealed and hardened (heat treated) condition. AMBICA STEELS PRODUCED VARIOUS STAINLESS STEEL PRODUCTS OF DIFFERENT GRADES, MARTENSITIC STAINLESS STEEL IS ONE OF THEM. If a stainless steel is mostly comprised of an austenite structure, then it will not be magnetic. Some ferritic stainless grades (such as types 409 and 405) cost less than other stainless steels. Ferritic Stainless Steels. Martensitic stainless steel is formed by the creation of martensite. Martensitic grades are magnetic in both the annealed and hardened (heat treated) condition. Martensite has been a key element of quenched steel for hundreds of years, but was officially named in the 20th century after the metallurgist Adolf Martens (1850 - 1914). The lower nickel content (compared to austenitic stainless steels) offers the secondary advantage of a lower material cost. Companies use martensitic stainless steel imostly in long products that require sheet and plate form. Martensitic stainless steels, such as types 403, 410, 410NiMo and 420 are magnetic and heat-treatable. With a microstructure that is half austenitic and half ferritic, duplex stainless steel has a higher strength than these types of stainless steel. This high levels of toughness and hardness associated with tempered martensitic stainless steels are why it is commonly chosen for the production of medical tools. Related martensitic and precipitation hardening stainless steel grades. Martensitic Stainless Steels, like the other Stainless Steel families, provide a Martensitic stainless steels are similar to ferritic steels in being based on chromium but have higher carbon levels up as high as 1%. Austenitic stainless steels tend to have a high chromium content compared to other steel alloys, giving them a higher resistance to corrosion. Martensitic stainless steels were the first stainless steels commercially developed (as cutlery) and have relatively high carbon content (0.1 - 1.2%) compared to other stainless steels. Austenitic Stainless Steels.These are the most frequently used types of stainless steels. ©2020 AK Steel Corporation.
