Difference from ASTM 304 and ASTM 201 stainless steel

Here is difference from ASTM 304 and ASTM 201 stainless steel.

Specifications: Commonly used stainless steel sheet into ASTM 201 and ASTM 304 stainless steel in two models, there are actually different components, ASTM 304 stainless steel of good quality, but the price is expensive, ASTM 201 stainless worse. ASTM 304 stainless steel imported stainless steel plate, ASTM 201 stainless steel for the domestic stainless steel plate.

ASTM 201 stainless steel composition of 17Cr-4.5Ni-6Mn-N, is the section Ni steel, 301 steel replacement steel, for railway vehicles.

ASTM 304 composition of 18Cr-9Ni, is the most widely used stainless steel, heat resistant steel. Used in food production equipment, chemical equipment through, nuclear energy.

ASTM 201 is high manganese, the surface is very bright with dark bright, high manganese easy to rust. ASTM 304 Chromium more matte surface rendering, does not rust. Had compared the two kinds together. The most important thing is different corrosion resistance, ASTM 201 corrosion resistance is poor, so the price will be much cheaper, and since ASTM 201 nickel-containing low, so it is better corrosion resistance of the ASTM 304.

ASTM 201 and ASTM 304 is the difference between the nickel issue. And the price of nickel are more expensive now, but the ASTM 304, then at least you can guarantee that the course will not rust.

Stainless steel rust is formed on the surface because the chromium-rich oxide protects the steel body, 201 is a high manganese steel hardness than the ASTM 304 carbon low-nickel.

Different components (mainly from the carbon, manganese, nickel, chromium aspects to distinguish ASTM 201 and ASTM 304 stainless steel)
