THK rails are mainly austenitic stainless steel and martensitic stainless steel. Austenitic stainless steel refers to stainless steel having an austenitic structure at normal temperature. The steel contains about 18% Cr, Ni 8%~10%, and C about 0.1%, and has a stable austenite structure. Austenitic chrome-nickel stainless steel includes the famous 18Cr-8Ni steel and a high-chromium-nickel series steel which is added with chromium, nickel content and added elements such as molybdenum, copper, silicon, niobium and titanium. Martensitic stainless steel is a stainless steel whose mechanical properties can be adjusted by heat treatment. Generally speaking, it is a kind of hardenable stainless steel. Typical grades are Cr13 type, such as 2Cr13, 3Cr13, 4Cr13 and the like. After quenching, the hardness is higher, and different tempering temperatures have different combinations of toughness and are mainly used for steam turbine blades, tableware, and surgical instruments. According to the difference in chemical composition, martensitic stainless steel can be divided into martensite chromium steel and martensitic chromium nickel steel.
