20 Gauge 321 Stainless Steel Sheets and Strips 2B Finish

As a direct factory of 20 gauge 321 stainless steel 2B finish, BEOBN will offer 20 gauge 321 stainless steel 2B finish sheets and 321 stainless steel 2B strips direct price. 20 Gauge 321 alloy steel sheet and strip is a stabilized stainless steel which offers as its main advantage an excellent resistance to intergranular corrosion following exposure to temperatures in the chromium carbide precipitation range from 800 to 1500°F (427 to 816°C). 20 gauge 321 stainless steel 2B finish sheet and strip is stabilized against chromium carbide formation by the addition of titanium. 321 stainless steel 2B finish sheet is non-magnetic.
While SS 321 2B finish sheet continues to be employed for prolonged service in th4e 800 to 1500°F (427 to 816°C) temperature range, 304L austenitic stainless steel 2B strip has supplanted this stabilized grade for applications involving only welding or short time heating.

20 Gauge 321 Stainless Steel Sheets and Strips Mechanical Properties:
Yield Strength, 0.2% Offset psi: 30,000
Ultimate Tensile Strength psi: 75,000
Percent Elongation in 2 in. or 51 mm: 40.0
Hardness, Max. RB (Sheet & Strip): 95
20 Gauge 321 stainless steel 2B finish sheet is also advantageous for high temperature service because of its good mechanical properties. Alloy 321 stainless steel offers higher creep and stress rupture properties than Type 304 and, particularly, Type 304L which might also be considered for exposures where sensitization and intergranular corrosion are concerns. This results in higher elevated temperature allowable stresses for this stabilized alloy for ASME Boiler and pressure Vessel Code applications. Inox 321 alloy has a maximum use temperature of 1500°F (816°C) for code applications like Type 304, whereas Type 304L is limited to 800° F (426°C).
321 austenitic stainless steel is particularly useful under conditions which cause polythionic acid stress corrosion of non-stabilized austenitic stainless steels such as Type 304. 321 austenitic stainless steel 2B sheet exposure of non-stabilized austenitic stainless steel to temperatures in the sensitizing range will cause the precipitation of chromium carbides at grain boundaries. On cooling to room temperature in a sulfide-containing environment, the sulfide (often hydrogen sulfide) reacts with moisture and oxygen to form polythionic acids which attach the sensitized grain boundaries. Under conditions of stress, intergranular cracks form. Polythionic acid SCC has occurred n oil refinery environments where sulfides are common. The stabilized 321 austenitic stainless steel 2B finish strips offers a solution to polythionic acids SCC by resisting sensitization during elevated temperature service. For optimum resistance, these alloys should be used in the thermally stabilized condition if service related conditions may result in sensitization.
