STAINLESS STEEL PIPES 321 manufacturer
Stainless 321 may be a heat resistant, metallic element stable, primary solid solution alloy that is usually used for service within the 1000°-1600°F temperature vary. 321 stainless is primarily employed in applications that involve continuous and intermittent service temperatures inside the inorganic compound precipitation vary of 800°-1600°F. Sort 321 is analogous to sort 304 stainless however with a metallic element addition of a minimum of 5 times the carbon content. This metallic element addition reduces or prevents carbide precipitation throughout attachment and within the 800°-1500°F service conditions. so as to supply immune to inter granular corrosion associate degreed to polythionic acid stress corrosion cracking in commission temperatures at 1500°-1650°F an air cool could also be used. Also have excellent weld ability in field.
