410 is a martensitic stainless steel that is predominately used in a wide variety wellhead applications. It is a very deep hardening, heat treatable stainless steel that contains Carbon, Manganese, and Chromium as the primary hardening elements.
Under the right heat treatment conditions, 410 is suitable for use in sour and CO2 environments.
80,000 psi or 85,000 minimum yield - limited to a Rockwell C -22 maximum for compliance NACE MR-01-75/ISO 15156 (for use in hydrogen sulfide environments)
Annealed or As-rolled - no mechanical properties; suitable for further heat treatment
