Two classes of heat-treated steel strips

With the accelerated pace of modern industrialization, machinery and equipment appear more and more frequently in people's life, people's pace of life is getting faster and faster, the demand for a variety of dairy products, drinks, fast food gradually increased, but also pulled the development of heat treatment steel strip industry. Heat treated steel strip is widely used in the market, which brings more kinds of products to people's life and brings benefits to many manufacturers. Heat treated steel strip is suitable for die cutting tool, etching tool die, corrosion tool die, large circular saw blade matrix, machine tool guide, railway connecting steel sheet and military products, etc. At present, this kind of large size heat treated high strength steel strip is completely imported, and is strictly restricted by the exporting country.

According to the production method, the heat-treated steel strip can be divided into hot-rolled and cold-drawn (rolled) heat-treated steel strip. The hot rolled heat treated steel strip includes round steel or trapezoidal steel for making spiral springs and torsion bars and flat steel for making plate springs; Cold drawn (rolled) heat treated steel strips include cold drawn steel wire for making small size coil springs and cold rolled steel strips for making spring and various spring pieces. Alloy heat treated steel strip usually contains manganese, silicon, chromium, molybdenum, tungsten, vanadium and trace boron, these alloy elements can improve the hardenability of steel, manganese and silicon solid into the ferrite, can improve the yield strength. Chromium, tungsten, vanadium can improve the elasticity, strength ratio and heat resistance of steel. The main products of Yongchang Metal Products Factory in Wuzhong District of Suzhou are all kinds of cold rolled steel strip, heat treated steel strip, spring steel strip, 65 manganese steel, 65mn steel strip, 60 steel, 50 steel, all kinds of ordinary steel strip, 195, 235, T8 and so on. According to the changes of the market, our company timely investigated and evaluated the market, and made the decision to add a heat treatment line which can produce ultra-thick and ultra-wide products. The production line is designed to produce heat treated steel strips with thickness of less than 6.0mm and width of less than 450mm.
