305 Stainless Steel Alloy Description:

305 grade stainless has similar corrosion resistance as 304 and has good oxidation resistance in air up to 1650 F (899 C). 305 can be readily formed and deep drawn into complex shapes due to its lower strength and work hardening rate and will remain nonmagnetic after cold work unlike 301 or 304. A caution is autogenous welds in 305 are more sensitive to hot cracking than 304 or 304L.

Industries supplied include:  

  • Tank covers
  • Other deep drawn parts
