Proven martensitic stainless steel offering reliable performance for valve components and standard oilfield applications in non-sour environments.
Economical choice for basic stainless requirements
Suitable for atmospheric and mild corrosive environments
Proven performance in valve bodies and components
Standard heat treatment and machining processes
Grade 410 has specific environmental limitations that must be considered for safe application.
Not suitable for sour service containing hydrogen sulfide
Limited resistance to high chloride concentrations
Maximum service temperature ~400°C (750°F)
NACE requires ≤22 HRC for sour service approval
