Super Duplex Stainless Steel Type - Standard Grade: UNSS32750 Duplex Stainless Steel Welding Rod (25Cr-7Ni-3.7Mo-0.3N)

The low-alloy type UNS S32304 is free of molybdenum and can be used instead of AISI 304 or 316 for stress corrosion resistance.

In the alloy type: UNS S31803 corrosion resistance between AISI316L and 6% Mo + N austenitic stainless steel. O6i4T9C

High alloy type: generally contains 25% Cr, also contains molybdenum nitrogen, and some also contain copper wall iron and tungsten, this type of steel corrosion resistance is higher than 22% Cr duplex stainless steel 9M S

Super Duplex stainless steel type: contains high molybdenum and nitrogen, some also contains tungsten and copper, also suitable for harsh media conditions, has a good corrosion resistance and mechanical properties, can be compared with super austenitic stainless steel U.S. No. Z3CNUD26• 05M (CD4MCu)
