Customer service center has a strong technical force of technical service team, composed of a customer service center manager, several 42CrMoS4 alloy steel material steel quality after-sales service personnel, responsible for unified acceptance and processing of local after-sales service needs.
Normalizing is a special case of annealing, the effect is similar to annealing, but the microstructure obtained by normalizing is finer. For low or medium carbon steel, normalizing can improve hardness and machinability. For 42CrMoS4 alloy steel material steel quality medium carbon steel and low alloy steel, normalizing can refine grain and uniform structure and reduce hardness. For high carbon steel and high alloy steel, normalizing can eliminate the network carbide produced by forging and improve the homogeneity of the preparation heat treatment structure.
20# seamless steel pipe chemical composition: C: 0.07-0.23, Si: 0.17-0.37, Mn: 0.35-0.65, Cr: 0.25, Ni: 0.30, Cu: 0.25. 20# seamless steel pipe mechanical properties: recommended heat treatment temperature: 910℃, tensile strength: 410 MPa, yield strength: 245 MPa, elongation: 25%, impact energy is not required. 20# seamless steel pipe hardness is higher than 10# seamless steel pipe. 42CrMoS4 alloy steel material steel quality, 20# seamless steel pipe has good weldability, no temper brittleness, and its machinability can be improved by water quenching. 20# seamless steel pipe can be used to make welded components, as well as parts with small load after forging, hot stamping and cutting.
