Hot rolled precision alloy steel cr40 pipe is one of the structural steels having a wide application. Due to its good mechanical properties, Cr40 steel bar is widely used in the production of important quenched and tempered mechanical parts, such as gear shaft sleeve, connecting rod, screw, inlet valve, and the mold manufacturing industry such as medium plastic mold and mold structure parts such as mold frame.
After tempering and tempering, the Cr40 steel has good comprehensive mechanical properties, low-temperature impact toughness, and low notch sensitivity. Except for quenching and tempering, Cr40 is also suitable for nitriding and high-frequency quenching. The hardenability of Cr40 steel is good, which can be reached to 28 ~ 60mm in water quenching and 15 ~ 40mm in oil quenching. When 174 ~ 229HBS, the relative machinability is 60%.
- Clean, smooth finish.
- Good welding performance.
- Good corrosion resistance, durable.
- High strength and high-temperature oxidation.
- Surface appearance and the use of the possibility of diversification.
Widely used in the automobile industry, fuel injection and also used in low, medium, and high-pressure boiler pipe, ship-building, etc.
