Oil and Gas Grades

  • Oil and Gas Grades


    Next Generation Metals is a leading distributor of stainless bar to manufacturers in the Oil and Gas Industry.

    410 QDT Stainless Steel is used for petrochemical applications such as oilfield sour gas hydrogen sulfide (H2S) services. This material is double tempered to relieve internal stresses and it also guarantees that no untempered martensite remains in the bar. The 410 QTD is certified with a minimum yield strength of 80 KSI and a hardness of RC22 max. This is in compliance with standards set for H2S-containing environments, NACE MR0175 and/or MR0103. The 410 QDT stainless grade also meets AP1 6A standards, making it optimal for resisting corrosion during petrochemical applications such as sour gas H2S services.

    Materials are manufactured and certified to the latest revision of these following specifications:


    • AISI 410-UNS S41000 (chem. only)
    • QQ-S-763F (chem. only)
    • ASTM A276/479/484 (chem. only)
