Delivery state of хардокс 450 specification

Rolling steel is the process of pressing to change the shape of the ingot and billet between the rotating rolls. The so-called steel rolling process is a combination of a series of steel rolling processes. The entire rolling production process is always composed of the following хардокс 450 specification basic processes: ① billet preparation:Including the cleaning of surface defects, the removal of surface scale and the pre-heat treatment of billets. ② billet heating ③ steel rolling: it is the core of the entire rolling production process. ④ Finishing.

The wear-resistant layer of wear-resistant steel plate is mainly composed of high-carbon and high-chromium alloy. According to the requirements of different users and service conditions, хардокс 450 specification, the high-temperature wear-resistant steel plate also contains alloy elements such as Mo, W, V, B, Nb, Ti, etc. The microstructure of the wear-resistant layer is eutectic + M7C3-secondary carbide or complex carbide. It can achieve high wear resistance of normal temperature, high temperature, strong impact, medium impact, and low stress impact.

хардокс 450 specification surface cracks refer to the linear cracks on the surface of хардокс 450 specification, which should generally be the same as the forging or rolling direction. Formation reason: it is mainly due to the hairline, hot crack and cold crack caused by surface over burning, decarburization, looseness, deformation and excessive internal stress during processing (forging, rolling, heat treatment, quenching and tempering), as well as the high content of sulfur and phosphorus impurities on the surface. Inspection method: хардокс 450 specification surface cracks can be detected by naked eye observation, acid pickling, magnetic particle inspection, coloring inspection and metallographic method.
