Precision Ground 304 Stainless Steel Plate
Precision ground 304 stainless steel plate is a kind of universal stainless steel material, which has better rust resistance than 200 series stainless steel material. High temperature resistance is also better. 304 stainless steel has excellent corrosion resistance and excellent corrosion resistance. For oxidizing acid, in the experiment: concentration ≤65% of the boiling temperature below the nitric acid, 304 stainless steel plate has a strong corrosion resistance. It also has good corrosion resistance to alkali solution and most organic acid and inorganic acid.
The density of 304 stainless steel plate 7.93 g/cm3 austenitic stainless steel generally used this value 304 chromium content (%) 17.00-19.00, nickel content.%) 8.00-10.00, 304 equivalent to China's 0Cr19Ni9 (0Cr18Ni9) stainless steel.304 stainless steel plate is widely used, with good corrosion resistance, heat resistance, low temperature strength and mechanical characteristics; Stamping, bending and other thermal processing, no heat treatment hardening phenomenon. Widely used in household products (1, 2 types of tableware), cabinets, indoor pipelines, water heaters, boilers, bathtubs, auto parts, medical appliances, building materials, chemicals, food industry, agriculture, ship parts.
If the surface of stainless steel plate oxide skin thickness is not uniform, thick place and thin place under the surface of the substrate metal finish is also different, surface and pickling when the surface of the dissolution of oxide skin and oxide skin adhesion parts of the substrate metal is different from the degree of acid erosion, so, the surface of the steel plate is not uniform. Therefore, in the heat treatment heating, must make it evenly formed oxide skin. To meet this requirement, attention must be paid to the following:
Precision ground 304 stainless steel plate.If the stainless steel plate in the heating workpiece surface adhesion oil, oil adhesion part of the oxide thickness and other parts of the oxide thickness and composition is different, and will produce carburizing.carbonized part of the oxidized subcutaneous matrix metal will be severely eroded.
Never be afraid to bother me, it is no matter if you have the regular supplier, just take a consideration while our products are the best price and high quality.
