16 Mn is a major steel grade of high strength low alloy steel plate in most industries, The consumption of this type is very large. Its intensity is higher than the ordinary p355gh steel carbon structural steel Q235 by 20% ~ 30%, atmospheric corrosion resistance by 20% ~ 38%.

Wear resistant steel is very wear-resistant: for example, excavator bucket, long-term excavation requires good wear resistance. Wear resistant steel has a very high hardness: for example, scraper conveyor, if the hardness is not up to standard, it is extremely easy to fracture, resulting in very serious consequences. Wear resistant steel has good corrosion resistance: many equipment need to transport chemical corrosion products, so corrosion-resistant mechanical equipment is needed. p355gh steel, Wear resistant steel has good fatigue resistance: such as bearing steel ball, which can do fast and repeated movement, and need to guarantee performance.

Quenching is a common heat treatment process. It is the metal heat treatment process in which the p355gh steel metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between p355gh steel strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.

p355gh steel, HP265 steel with the thickness range is 1.2-12mm. HP265 steel’s mechanical properties is include the yield strength more than 265MPa, tensile strength is 410-520MPa. The chemical composition of HP265 steel is C element content is 0.18, the Si element content is 0.10, the Mn element content is 0.80, the P element content is 0.025% max, the S element content is 0.015% max.

If customers have any difficult problems during use of the steel materials, they can contact the company's after-sales service department to feedback the existing problems. The after-sales department will reply as soon as possible to ensure that each customer has a good after-sales experience. Under special circumstances, the after-sales service department will start the problem-solving process, and the engineers in charge of the area will quickly follow up to solve the problem.
