Corrosion resistance
It performs well in corrosive media containing chloride ions (such as seawater, salt water), sulfuric acid, phosphoric acid, etc. The critical pitting temperature is ≥35℃, and the corrosion resistance is significantly better than 304 stainless steel.
High temperature resistance
It can withstand high temperature environments up to 870℃ and still maintain stable mechanical properties, suitable for high-temperature industrial scenarios.
Mechanical properties
Tensile strength ≥480MPa, yield strength ≥170MPa, elongation ≥40%, with both high strength and toughness.
Processing characteristics
It supports TIG/MIG welding process, and the cold rolling deformation can reach 60%, but after forming, solution treatment (1050–1100℃ water quenching) is required to restore corrosion resistance.
Applicable scenarios
It is widely used in chemical equipment, marine engineering, oil and gas pipelines and other fields with high requirements for corrosion resistance and high temperature performance

Composition of Stainless Steel
Steel is an alloy of iron and carbon. Stainless steels are steels containing at least 10.5% chromium, less than 1.2% carbon and other alloying elements. Stainless steel’s corrosion resistance and
mechanical properties can be further enhanced by adding other elements, such as nickel, molybdenum, titanium, niobium, manganese, etc.
