Product Name: stainless steel, stainless steel precision strip, stainless steel strap, stainless steel bright, stainless steel coil, stainless steel strip, etc. ?? Material:? 201/304/301 / 316L / 310S / 420/430/410 / 420J2 tool steel with other specifications:? thickness of 0.01 ~ 3.0mm width] [1 ~ 1220mm narrowest divided into 1mm Hardness:?? 120HV-580HV [1 / 2H semi-hard, 3 / 4H, 1 / 4H, full hard] processed?: ? punching, leveling, slitting, cut, foil, surface treatment, stretching and other theoretical weight (Unit: kg / m, mm):? L * W * Thickness * 7.93 = per piece / kg-use products are widely used in machinery manufacturing, industrial facilities, pharmaceutical / medical equipment, kitchenware, shipbuilding industry, automobile industry, kitchen utensils, water, electricity, refrigeration, bridges, boilers, armor, roof, solar energy, metal products, construction materials, elevator decoration, metal tank shell, ship, train interiors, construction, aviation, submarine engineering, environmental protection and other industries performance:?? and other materials, the physical properties of stainless steel including the following three aspects: melting point, specific heat capacity, thermal conductivity and thermal expansion mechanical quality factor and other electromagnetic properties of thermal performance, electrical resistivity, conductivity and permeability, as well as Young's modulus, stiffness coefficient. These properties are generally considered to be the inherent characteristics of the stainless steel material, but will also be affected, such as the temperature, the degree of processing and the magnetic field strength and the like. Often compared to stainless steel and iron, low thermal conductivity, resistance, and the linear expansion coefficient and permeability and other properties of the crystalline structure of the stainless steel itself, according to another.
