The chemical composition of 20CrMo steel pipe is 0.17-0.24, Si: 0.17-0.37, Mn: 0.40-0.70, Cr: 0.80-1.10, Mo: 0.15-0.25. Mechanical properties of 20CrMo steel pipe: tensile strength 410 Mpa; yield strength: 265mpa; elongation after fracture: 24; reduction of area: 60; impact absorption energy: 110J. 20CrMo steel pipe belongs to alloy structure steel pipe, which has high thermal strength, good high-temperature strength, good machinability, medium cold bending plasticity, high hardenability and good welding performance at 500-520℃. A283 grade A CS steel carbon plate, 20CrMo steel pipe is generally used in quenching and tempering state.
The metallurgical quality of spring steel should reach the level of high quality steel. Due to the special requirements of production parts, A283 grade A CS steel carbon plate, spring steel must have some characteristics. First, the fatigue resistance of spring steel is good, and it can be restored to its original state after repeated use without deformation. Second, good flexibility. Third, the tensile strength of spring steel is good, under the limit of being stretched, it can be restored without breaking.
The company strengthens process management and pays attention to assessment. One of the key points of good service is to strengthen the process management and improve the evaluation mechanism. Make the after-sales service system more perfect and provide better service for customers.
