UNS S41426 : UNS S41427
Both grades developed from the standard 13Cr and 420 Modified grades offer enhanced mechanical properties and corrosion resistance. The low carbon improves weldability whilst maintaining the martensitic microstructure.
Available in bar or tube form, its main application is within the OCTG tubing & casing and downhole completion equipment.
The Sumitomo grade is NACE MR0175 approved subject to a hardness limitation of 27 HRC and a yield strength of 105 KSI.
When bill of material requirements can be matched against the wide stock of sizes available, considerable cost savings in both raw material supply and manufacturing are achievable against the comparable bar product.
