15CrMo round steel spot 15CrMo cutting price

Round steel is alloy structural steel. Shanghai Tengzhong Industry and Trade Co., Ltd. has long-term distribution as follows:,,,,,,,B,B,,,,,,,,B and other alloy structural steels. Round steel has good process performance and welding performance, and has high lasting strength at ~℃. When the temperature exceeds ℃, the anti-oxidation performance becomes worse and the creep strength is significantly reduced. When exposed to ~℃ for a long time, the thermal strength of steel decreases and the strength decreases. It is used to manufacture high and medium pressure steam pipes, headers, superheaters and forgings with a tube wall temperature of ℃. Alloy structural steel is generally divided into quenched and tempered structural steel and surface-hardened structural steel. ① The carbon content of quenched and tempered structural steel is generally about .~. For structural parts with a given cross-section size, during the quenching and tempering treatment (quenching and tempering), if it is quenched along the cross-section, the mechanical properties will be good. If it cannot be quenched thoroughly and free ferrite appears in the microstructure, the toughness will decrease. For steels with tempering brittleness tendency, such as manganese steel, chromium steel, nickel-chromium steel, etc., they should be cooled quickly after tempering. The quenching critical diameter of this type of steel increases with the increase in grain size and alloying element content. For example, He3 steel is about 3~, while He3 steel is about ~. It is often used to manufacture shafts that bear larger loads. , connecting rods and other structural parts. ②Case hardened structural steel is used to make parts with hard and wear-resistant surfaces and flexible cores, such as gears, shafts, etc. In order to ensure high toughness in the core of the part, the carbon content in the steel should be low, generally between . Nitrided steel also needs to add alloying elements that easily form nitrides (such as, , etc.). Carburized or carbonitrided steel, after carburizing or carbonitriding at ~℃, is quenched and used in a low temperature tempering (about ℃) state. Nitrided steel has been nitrided (~℃) and used directly without quenching and tempering.
