Mechanical properties of S420NL-Z35 steel plate: yield strength≥235Mpa, tensile strength 360-510Mpa, elongation≥26%. The properties of a633 steel, S420NL-Z35 steel plate determine its application. S420NL-Z35 steel plate has high strength and good welding performance, which is commonly used in the manufacturing of mining machinery, engineering machinery, coal mine hydraulic support and other equipment and structural parts.
Strip steel is mainly divided into hot-rolled ordinary strip steel, cold-rolled ordinary strip steel, hot-rolled high-quality strip steel and cold-rolled high-quality strip steel. The a633 steel, hot-rolled carbon strip steel is made of ordinary carbon structural steel, and is hot-rolled into strip steel with a thickness of 1.80-6.00mm and a width of 50-1200mm. The hot-rolled carbon strip steel is mainly used for the manufacture of cold-rolled billets, cold-formed steel billets, welded steel pipe billets, bicycles, and small hardware products.
Non-secondary a633 steel product hot selling: 26*1500*9950, 23.5*2040*8100, 24*1500*6700, 23.5*1640*6550, 29*2140*7700, 30*1500*6000, 24*2000*9550, 26.5*2000*7000, 26*1600*6000, 32*1570*6000, 32.5*1560*6250, 25.5*1300*6000, 27*2550*6800, 27.5*2700*5500, 33*2340*6700, 34*1300*4000, 25.5*1740*8700, 29*2550*9000, 29*2870*12000, 26*1300*8100, 32.5*3050*6500.
In order to obtain the seamless tube with smaller size and better quality, the method of cold rolling, cold drawing or the combination of the two must be used. Cold rolling is usually carried out on a two high mill, and a633 steel pipes are rolled in a circular pass composed of a variable cross-section circular groove and a fixed conical head. Cold drawing is usually carried out on single chain or double chain cold drawing machines of 0.5-100t.
