The stainless steel welded pipe mold is formed on a welded pipe forming machine by rolling a stainless steel plate through several molds and then welding. Due to the high strength of stainless steel, and its structure is a face-centered cubic lattice, it is easy to form work hardening, so that when

The chemical composition of the high chromium cast iron roll is: 2.0% ~ 4.0%C, 10% ~ 30%Cr, 0.15% ~ 1.6%nI, 0.3% ~ 2.9%Mo. Its essence is a high-alloy white iron with high wear resistance. The chromium content is generally 10% ~ 15%. Its carbides are mainly M7C3 type, which is different from the con

The development direction of cold rolls will be to further improve the strength, hardness and depth of the hardened layer, while ensuring a certain degree of toughness. Large-scale cold-rolling work rolls will generally be made of improved 5% Cr steel containing vanadium, milling, nickel and other e
