321 قضيب/قضبان زاوية من الفولاذ المقاوم للصدأ 321

Main features of 321 stainless steel angle steel:

Corrosion resistance: 321 stainless steel angle steel has good wear resistance in organic and inorganic acids of different concentrations and temperatures, especially in oxidizing media. It is suitable for manufacturing linings and pipelines of wear-resistant acid containers and wear-resistant equipment.

High temperature performance: 321 stainless steel angle steel is a heat-resistant steel grade, which is much better than 316L in terms of high temperature. It has excellent high-temperature stress rupture performance and high-temperature creep resistance, and its stress mechanical properties are better than 304 stainless steel.

Chemical composition: The chemical composition of 321 stainless steel angle steel includes carbon (C), silicon (Si), chromium (Cr), nickel (Ni) and other elements, among which titanium (Ti) exists as a stabilizing element, which effectively controls the formation of chromium carbide.

Physical properties: The tensile strength σb of 321 stainless steel angle steel is not less than 520MPa, the elongation δ5 is not less than 40%, and the hardness does not exceed 187HB, 90HRB or 200HV.

Application fields: Due to its excellent corrosion resistance and high temperature performance, 321 stainless steel angle steel is widely used in petroleum, chemical, coal, electric power and other industries, such as oil waste gas combustion pipelines, engine exhaust pipes, boiler shells, heat exchangers, heating furnace parts, etc.
