When 321 stainless steel contains about 18% Cr, 8% to 25% Ni, and about 0.1% C, it has a stable austenite structure. Austenitic chromium-nickel stainless steel includes the famous 18Cr-8Ni steel and high Cr-Ni series steel developed by adding Cr and Ni content and adding Mo, Cu, Si, Nb, Ti and other elements on this basis. Because 321 stainless steel has comprehensive and good comprehensive properties, it has been widely used in all walks of life.The company adheres to the Q355NH steel structure external market, internal management, quality and efficiency oriented development path, and has achieved good economic and social benefits. With strong financial strength, advanced management experience, excellent sales service, strict quality management system and scientific overall marketing means, we will work hand in hand with you for common development. We are making all efforts working on the optimization of Q355NH steel structure quality and price and best service for all our customers.The company currently has a number of extended steel processing capabilities such as laser cutting, bending, rolling, welding, pipe making, and surface treatment, and can provide customers with diversified products and services. In addition, the company has strong technical force, complete production equipment and advanced production technology. The testing methods are perfect and the Q355NH steel structure product quality is high.The addition of Ca element in steel such as Q355NH steel structure can refine grain size, partly desulphurize and change the composition, quantity and morphology of non-metallic inclusions. It is similar to that of adding rare earth in steel. It can improve the corrosion resistance, wear resistance, high temperature and low temperature resistance of steel, improve the impact toughness, fatigue strength, plasticity and welding performance of the steel, and increase the cold heading, shock resistance, hardness and contact endurance strength of the steel.Since its establishment, the company has been deeply supported and loved by customers with its unique business philosophy and business model. The company has always adhered to the tenet of "credibility first, integrity-based, quality first" and sincerely serves new and old customers.
