ASTM A182 Stainless Steel 316H Flange
GNEE is the main supplier of ASME 316H flanges, we provide high quality high temperature corrosion resistant flanges to customers around the world according to their needs.
ASTM A182 316H stainless steel flange is a high carbon version of grade 316, ASTM A182 SS 316H flange has high tensile strength due to the presence of high carbon content, which gives it a longer shelf life in high pressure working environments. ASTM A182 316H Steel The chemical composition of the flange contains 2%-3% molybdenum, which can safely corrode certain forms and increase its corrosion resistance.
Flange sliding and weld neck flanges are the most popular flanges among ASTM A182 316H grade flanges, ASTM A182 316H weld neck flanges provide the best support for piping modules during high pressure and temperature fluctuations throughout the system. ASTM A182 316H slip flange is used in low pressure and cryogenic systems.
