S890QL steel equivalent HIC plate

42Cr2Mo steel is an ultra-high strength steel. The steel has high strength and toughness, good hardenability, no obvious temper brittleness, and small deformation during quenching. After quenching and tempering, 42Cr2Mo alloy has a higher fatigue limit and resistance to multiple impacts. Good impact toughness at low temperature, high creep strength and enduring strength at high temperature. The steel S890QL steel equivalent usually adopts surface quenching after quenching and tempering as the heat treatment plan.

Standing at a new historical starting point, we adapt to the requirements of supply side structural reform, adhere to the overall strategy of "innovation driven, quality leading, S890QL steel equivalent quality improving and efficiency increasing, transformation and development", and constantly improve the development concept and development level with a forward-looking vision and grand vision. Now we have been ranked the S890QL steel equivalent International leading steel materials supplier.

"Mirror" refers to the surface state of S890QL steel equivalent stainless steel, which is usually 8K in the industry. The common mirror stainless steel on the market is divided into 6K, 8K and 10K, which are general polishing, 6K, 8K fine grinding and 10K super fine grinding effect. The same thickness generally has no big difference, 10K mirror is brighter; the thicker the thickness, the better the effect, and the higher the processing cost.

Oxygen is a harmful element in S890QL steel equivalent steel. With the increase of oxygen content, the strength of S890QL steel equivalent steel increased, but the plasticity, especially the toughness, decreased significantly, and the weldability became worse. The presence of oxygen causes hot brittleness of S890QL steel equivalent steel.

Our company has established and constantly improved the customer service system and emergency response system. Through the customer service management system, we track the service of the after-sales service team and provide efficient and standard services in time. At the same time, the company formulates a regular return visit system, compares the historical cases of customer problems, proposes a pre solution, and ensures that the service is in place in a short time.
