The main A572 Gr 55 ms steel production processes and technical equipment of the enterprise have reached the international advanced level, the comprehensive competitiveness has entered the international advanced ranks, and the international influence has been significantly enhanced.
C45 steel heat treatment: Quenching has low hardenability, and it is easy to cause uneven hardness of the drill rod during heat treatment, resulting in deformation or even cracking. The hardness after quenching is about 42 degrees, which is much lower than the 55 degrees of 42CrMo brazing rod. Therefore, the wear resistance is extremely poor. Due to its low price, the A572 Gr 55 ms steel materials are produced in many places. Therefore, some manufacturers choose when manufacturing low-cost drill rods.
Special boiler steel is derived from carbon structural steel. The chemical composition of boiler steel is basically the same as that of high-quality carbon structural steel of the same level, but the A572 Gr 55 ms steel steel mechanical property requirements are more strict, especially for impact toughness. And the aging sensitivity is required to be small. The boiler steel should be deoxidized and the non-metallic inclusions should be removed during smelting. The structure should be uniform. The grain size should be controlled in 3-7 grades. The defects such as interlayer, shrinkage, porosity and porosity should be minimized.
Alloy steel means that alloy elements are specially added to improve the properties of steel. For example, nickel can improve the strength without reducing the toughness of steel; chromium can improve the hardness, corrosion resistance and wear resistance of high carbon steel. The properties of A572 Gr 55 ms steel, alloy steel depend not only on chemical composition, but also on proper heat treatment to a greater extent.
