904L super austenitic stainless steel is a low-carbon, high-nickel, molybdenum austenitic stainless acid-resistant steel.

It has good activation-passivation transformation ability, excellent corrosion resistance, good corrosion resistance in non-oxidizing acids such as sulfuric acid, acetic acid, formic acid, and phosphoric acid, good pitting resistance in neutral chloride ion media, and good crevice corrosion resistance and stress corrosion resistance.

It is suitable for various concentrations of sulfuric acid below 70°C and has good corrosion resistance in acetic acid of any concentration and any temperature under normal pressure, and mixed acid of formic acid and acetic acid.

Duplex Stainless Steel Wire Mesh

Duplex Stainless Steel (DSS) wire mesh refers to stainless steel in which ferrite and austenite each account for about 50%.
Generally, the content of the smaller phase needs to be at least 30%. In the case of low C content, the Cr content is 18%~28% and the Ni content is 3%~10%.

duplex stainless steel wire mesh is an economical corrosion-resistant stainless steel.
super duplex stainless steel wire mesh has excellent resistance to pitting corrosion, crevice corrosion, and uniform corrosion.

430 Stainless Steel Wire Mesh

430 stainless steel wire mesh is low in price and good in processing. It is an ideal substitute for SUS304.
It has good stress corrosion resistance and is a typical non-heat-treated hardened ferritic stainless steel. It has a low thermal expansion coefficient and excellent oxidation resistance.

What is the Difference Between 304 and 430 Grade Stainless Steel?

The differences between 430 stainless steel and 304 stainless steel are mainly in the following aspects. &#;

&#;Chemical composition&#;:

430 stainless steel mainly contains about 16-18% chromium, and it belongs to ferritic stainless steel.
304 stainless steel mainly contains about 18-20% chromium and about 8-10% nickel, and it belongs to austenitic stainless steel. &#;

Mechanical properties&#;:

430 stainless steel has high strength, but poor plasticity and toughness, and is prone to cold brittleness.
304 stainless steel has low strength, but has good plasticity and toughness. &#;

Corrosion resistance&#;:

430 stainless steel has good corrosion resistance in dry air, but is prone to corrosion in humid or acidic environments, and has poor corrosion resistance to strong acids such as nitric acid and sulfuric acid.
304 stainless steel has good corrosion resistance, can resist the erosion of most acidic and alkaline media, and has strong resistance to chloride corrosion. &#;
