Welcome to BBN High Strength Steels Factory
The difference between S460 steel equivalent, hot rolled sheet and cold rolled sheet: hot rolled sheet has low hardness, easy processing and good ductility. The cold-rolled sheet has high hardness and relatively difficult processing, but it is not easy to deform and has high strength. The cold rolled sheet is mostly used in automobile manufacturing and electrical products. Therefore, the two have their own characteristics. According to these characteristics, it is more appropriate to choose the right rolled plate to maximize its effect and benefit.

S460 steel equivalent surface cracks refer to the linear cracks on the surface of S460 steel equivalent, 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: S460 steel equivalent surface cracks can be detected by naked eye observation, acid pickling, magnetic particle inspection, coloring inspection and metallographic method.
The basic principle of S460 steel equivalent, heat treatment of steel: put the metal workpiece in a certain medium and heat it to a suitable temperature, keep it in this temperature for a certain time, and then cool it at different speeds. Objective: to obtain the desired structure and properties by means of heating, heat preservation and cooling, so as to make the metal workpiece have the required mechanical, physical and chemical properties.
