Stainless Steel 321 is an 18/8 austenitic steel that is stabilized with Titanium. This grade can be used in high-temperature applications up to 900°C. It also offers excellent strength, resistance to aqueous corrosion in addition to the scaling and phase stability. While on the other hand, Stainless Steel 321H is a modification of Stainless Steel 321. Grade 321H contains more but controlled carbon content, which results in improved strength to deal with high temperatures. Similar to other austenitic grades, Stainless Steel 321/321H has splendid forming and welding characteristics. It also shows excellent toughness at cryogenic temperatures.
