Stainless steel chain plate corrosion resistance
304 is a universal stainless steel, it is widely
used to produce good overall performance requirements
(corrosion resistance and formability) of equipment and parts.
304L is a low carbon 304 stainless steel variant of the occasion
for the need for welding. Lower carbon content makes it close
to the weld in the heat affected zone to minimize carbide precipitation,
and carbide precipitation may result in some environments, stainless steel,
intergranular corrosion (weld erosion).
316 and 317 stainless steel with aluminum, so the chemical industry in the
marine environment and the point of corrosion resistance far superior to 304
stainless steel. Among them, 316 stainless steel, including low carbon steel by
a variant of 316L, 316N nitrogen and high-strength stainless steel combined with higher sulfur free cutting stainless steel 316F.
904L (00Cr20Ni25Mo4.5Cu) is a low-carbon high-nickel, molybdenum austenitic stainless acid-resistant steel. Has a good active - passive transition ability, excellent corrosion resistance, in non-oxidizing acid such as sulfuric acid, acetic acid, formic acid, phosphoric acid has good
corrosion resistance, chloride ions in neutral medium with good The resistance to pitting
corrosion resistance, but also has good resistance to crevice corrosion and stress
corrosion resistance. Below 70 íŠ for various concentrations of sulfuric acid, resistance to
any concentration in the atmospheric pressure, any temperature of acetic acid and formic
acid and acetic acid mixture is also very good corrosion resistance.
