Doshi Nickel Alloys

Duplex Steel S2205 Welded Pipes is nitrogen enhanced stainless steel that was developed to combat common corrosion problems encountered with the 300 series stainless steels. Duplex Steel S31803 EFW Pipes combines improved resistance to stress corrosion cracking, pitting, crevice corrosion and high strength in comparison with other stainless steel grades.

410 Stainless Steel Pipe is made up of martensitic steel. Martensitic steels are used when the strength and toughness are needed along with high wear and tear resistance. Their corrosion resistance is lower than the austenitic stainless steels in general. The 410 SS Pipe material has carbon, manganese, silicon, phosphorus, sulfur, chromium and nickel in its material composition. This specific composition provides it with the high wear and tear resistance.

Super duplex pipes produced under specification ASTM A790, are supplied in a seamless or a welded construction. The automatic process used to manufacture Super Duplex Welded Pipe is without the use of a filler metal. The Super Duplex Pipe suppliers recommend using these pipes for applications that are prone to general corrosion resistance
