Stainless, Duplex, Super Duplex

Stainless steel and duplex steels play a safety critical role in the oil and gas industries. Modern refineries produce around 100,000 barrels of oil per day, through several processes involving intense heat, corrosive liquids, and toxic gases.

The process uses an intricate series of safety valves and components, where Stainless and Duplex steels are often used for their high corrosion resistance - minimizing downtime and maximizing output.

Howco's extensive range of high integrity Stainless and Duplex steels such as -- 13 Cr and Super 13 Cr precipitation hardening Stainless, and 22 Cr and 25 Cr Duplex grades in both Tubular and Bar products is available from Howco locations worldwide.

For Stainless or Duplex requirements call Howco direct.
