Product List |
Stainless steel 321H flanges have oxidation resistance to 16,000°F.
Developed to provide an 18-8 type alloy with improved resistance to
intergranular corrosion. SS 321H flanges do not exhibit weld rot
(intergranular corrosion) in mildly corrosive environments. SS 321H
blind flanges are a titanium-stabilized chromium-nickel austenitic
stainless steel with good strength and excellent corrosion
resistance, supplied in the annealed condition. SS 321H plate
flanges can be easily formed and drawn.
However, higher pressure requirements and more springback are
encountered than with carbon and ferritic stainless steels. Stress
Relief - Heat this stainless steel 321H socket eld flange up to
700°C for 1 to 2 hours with air cooling. s$ 321H threaded flange
contains 18% chromium, 8% nickel and a significant addition of
titanium.
Characteristic of ASTM A182 F321H
High temperature resistance: It has good high temperature
resistance and can maintain good strength and corrosion resistance
under high temperature environment.
Corrosion resistance: It has good corrosion resistance, especially
for chloride and sulfuric acid and other corrosive media with good
resistance.
High strength: It has high tensile strength and yield strength,
making it suitable for high strength requirements of engineering
applications.
Weldability: It has good weldability, can be connected by various
common welding methods.
