S890QL steel hardness steel from BBN is great and cheap

Based on the main business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and S890QL steel hardness heavy plate, hot rolled coil, section steel, steel tube, etc., which are widely used in automobile, oil, railway, bridge, construction, electricity, transportation, machinery, shipbuilding and other important fields. Our steel products are exported S890QL steel hardness to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.

The company has a group of experienced steel plate continuous processing line construction, production management, operation and professional and technical personnel. The company is a modern enterprise integrating scientific research and development, production processing, sales and service. Our main products include hot rolled plates, seamless pipes, S890QL steel hardness and steel structures. At the same time, it also adheres to international standards and adheres to the international line.

Compared with 15Cr steel, 20Cr alloy has higher strength and hardenability. The critical hardening diameter in oil is 4-22mm, and the critical hardening diameter in water is 11-40mm, but the toughness is poor. This S890QL steel hardness alloy steel S890QL steel hardness still has a tendency to grow grains during carburization, and direct quenching at lower temperature has a greater impact on impact toughness, so secondary quenching is required after carburization to improve the toughness of the core of the part, and there is no temper brittleness.

We specialize in the production and sale of steel products. We have many customers from all over the world. Our products S890QL steel hardness have strict quality inspection departments, so we have absolute quality and technical advantages. Good promotion system, with advanced business philosophy, create development space, enhance the value of employees, improve the quality of life as the mission. Pursuing green procurement, energy conservation and consumption reduction.
