Martensitic stainless steel is Fe-Cr-C ternary alloys based, under the presence of such a high temperature austenitic steel in the air cold conditions sufficient to produce austenite to martensite, which belongs to hardened Organization of steel. Relative to other types of stainless steel; martensitic stainless steel can reach a very wide range of intensities, and lining D6 poor clumsy turn Hsin holding some. Fire Status 7a, high hardness, corrosion resistance and weldability, but some poor handling of the mechanical properties of martensitic steels great impact shall be supplied in accordance with the requirements of the provisions of the state, or annealed condition, or fire + tempered condition . Martensitic stainless steel is not suitable for use in highly corrosive media, but for strength and wear resistance has certain requirements, structural corrosion resistance under less demanding work environment is very appropriate. Martensitic stainless steel types are as follows. ①Cr13 Department of martensitic steel Cr13 series martensitic stainless steels in the most typical, as lCr13,2Cr13,3Cr13,4Cr13 and lCr17Ni12 like. Most commonly referred to as martensitic steel refers to this type of steel, these air-cooled stainless steel heated to high temperatures can be hardened, generally after quenching. ② Cr12 heat resistant martensitic steels is based multivariate alloyed martensitic stainless steel, such as. lCr12WMoV, 2Cr12MoV, 2Cr12Ni3MoV, etc., used as a heat resistant steel. After air-cooled high-temperature heating can also be hardened. Due to the high temperature, the temperature was raised to want to use ordinary steel Cr13 limit temperature above 600 ℃, adding Mo, W, v, and will also mention some of the carbon. Therefore, heat resistant martensitic steels hardened tendency will be even greater, generally after quenching and tempering. ③ multiphase ultra-low carbon martensitic steel which is a new high-strength martensitic steels. Component is characterized by the carbon content of steel wlc reduced to 0.05% or less and added Ni (71) Ni = 4% - 7%), and may also contain a small amount of Mo, Ti or Si. A typical steel grades such as o. OIC-13Cr-7Ni-3Si, 0. 03C-12. 5Cr-4Ni-0. 3Ti, 0. 03C-12. 5Cr-5. 3Ni-0. 3Moo these types of steel have been ultrafine Composite tissue hardening and tempering treatment, a high strength and high toughness. This steel may also be quenched in use because there is no low-carbon martensite and high brittleness. Welcome to inquire, Tel: Wei Xia 18024146844 QQ: 36310958
