S890QL hardness, GB/T 16270 Q460C heavy plate is a high strength structural steel grade in quenched and tempered condition. Product S890QL hardness stock size(mm) 6*2140*13000, 6*2080*8400, 45*1580*4900, 16*2200*9600, 12*2530*4100, 26.2*3082*4500, 16*1800*10000, 6*2160*8600, 14.5*2800*6400, 20*1600*12600, 6*2140*11500, 6*1590*8600, 22*1800*6000, 25*1800*8229, 12*2200*4300, 6*2080*8700,28.58*4343*12300, 40*2500*3400, and 81*2180*5000.

Steel can be divided into ordinary steel and special steel, which is an important symbol of a country's steel production level. The special steel includes spring steel, round steel, die steel, heat-resistant steel, wear-resistant steel, bearing steel and so on. Compared with ordinary steel, the S890QL hardness special steel has better physical properties, higher strength, stronger compressive strength and better accuracy. At the same time, the special steel has better chemical properties, such as high temperature resistance, low temperature resistance and corrosion resistance.

As one of the large professional metallurgical manufacturers in China, the strength of the brand, quality assurance, professional after-sales. Every day we are making unremitting efforts to challenge higher quality S890QL hardness products and more satisfactory services. Customer demand is our pursuit, and win customer satisfaction with quality. BBN after-sales team is responsible to solve the problem of technical support and quality, service complaints.

The company's products S890QL hardness have excellent quality, reasonable prices and strong usability, and are well received by users. Survive by quality, expand the market with integrity, continuously research and develop new products, expand varieties, to meet market demand, and make the company continue to grow. The needs and interests of users are our high philosophy of service and commitment, and customer satisfaction is our eternal pursuit.
