UNS S50400 : ASTM A213 (VO1.01)
A martensitic steel containing 9% Chromium and 1% Molybdenum is most commonly used in the hardened and tempered condition.
Though often referred to as a stainless steel the grade does not meet the accepted criteria to be considered a stainless steel.
Used extensively as tubulars, and structural and pressure containing members and is listed in NACE MR0175 Table 6 as an acceptable material for sub-surface components.
This alloy may be subject to accelerated local corrosion in environments containing free oxygen.
When bill of material requirements can be matched against the wide stock sizes available considerable cost savings in both raw material supply and manufacturing are achievable against the comparable bar product.
