ASTM 304 Stainless Steel Plate

ASTM 304 stainless steel plate is a kind of common stainless steel materials, rust resistance than 200 series stainless steel materials were also better 304 stainless steel has good resistance to high temperature corrosion and corrosion resistance and good resistance to intergranular corrosion properties of oxidizing acid, it is concluded that: in the experimental concentration below the boiling temperature of nitric acid of 65%, 304 stainless steel has a strong corrosion resistance to most organic and inorganic acid and alkali solution with good corrosion resistance ability.

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 l stainless steel plate has much less carbon than 304. 304L is superior to 304 in pitting resistance to welding or other treatments.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.

Corrosion resistance of stainless steel mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, etc.) and internal structure, the main role is chromium. Chromium has high chemical stability, can form passivation film on the steel surface, make the metal and the outside world isolated, protect the steel plate from oxidation, increase the corrosion resistance of the steel plate. After the passivation film is destroyed, the corrosion resistance decreases.

ASTM 304 stainless steel plate.The surface of stainless steel plate is smooth and clean. It has high plasticity, toughness and mechanical strength. It is resistant to corrosion of acid, alkaline gas, solution and other media. It is an alloy steel that does not rust easily, but it is not absolutely rust free.

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.
