Difference between 202 stainless steel and 304 stainless steel

202 stainless steel and 304 stainless steel are relatively common, but the 202 stainless steel and 304 stainless steel is very different here,Bebon International for your detailed explanation as Chinese steel exporter.

202: China corresponding grades 12Cr18Mn9Ni5N

Nickel Copper 1.5% 1.0% or more known as the high copper material.

0.5 to 0.8% nickel, 0.8 to 1.0% of copper in the copper or copper half.

Nickel containing less than 0.5, excluding copper, low copper material with nickel content of price and performance is proportional to

304, only containing 7.0% Ni and 8.0% Ni are two, 304 corresponding to the Chinese grades 1Cr18Ni9.

202 stainless steel is widely used in building decoration, municipal engineering, highway guardrail, hotel facilities, shopping malls, glass handrails, public facilities and other places. By a precision automated pipe equipment, through its own eclipse melting welding, rolled and shaped, in the absence of any metal filler, the filled gas (inner and outer tube) welded together, for the TIG welding process, and make the vortex line solution testing.

304 stainless steel is a versatile stainless steel, rust-resistant stainless steel is stronger than the 202. High temperature also relatively good, the general temperature limit is less than 650 ℃ . 304 stainless steel with excellent corrosion resistance and good resistance to intergranular corrosion. On the oxidizing acid, in the experiment: the concentration of ≤ 65% of the boiling temperature of nitric acid, 304 stainless steel is highly resistant to corrosion. Alkali solution and organic acids and inorganic acids also have good corrosion resistance.
