Round Bars Super 13Cr 95Ksi Blank Pipe UNS S41427 (Grade 13-5-2) Solid Bars
This specification pertains to UNS S41425, UNS S41426, UNS S41427 and other super 13 chromium
stainless steels that contain nominal chromium, nickel and molybdenum contents of 13%, 5% and 2% respectively. The product will be in the heat treated (quenched & tempered) condition. Material meeting the requirements of this specification shall exhibit a minimum yield strength of 110 ksi. This material does not meet NACE MR0175/ISO 15156 and caution is required when H2S is present. These stainless steels are used primarily for resistance to CO2corrosion. When there is an apparent conflict or difference between this specification and a referenced specification, this specification shall govern.
