300 Series
High strength
Scaling resistance and phase stability
Excellent forming and welding characteristics
Resistant to potable water with up to 200mg/L chlorides at normal temperature.
321 Stainless Steel
This is a standard austenitic 18/8 stainless steel grade, (304), but stabilized by Titanium. The titanium within means the stainless steel is intergranular corrosion resistant after heating, (between 425-900 degrees Celsius). Remarkably high strength as well as scaling resistance and phase stability set 321 Stainless Steel apart from other similar grades. This grade is not, however, recommended for welding consumable, as the titanium component does not allow good transfer of heat across a high-temperature arc.
