The increasing use of nickel alloys in natural gas production led to the development of the high- strength, corrosion resistant, age-hardenable alloy 925 (N09925). Alloy 925 offers corrosion resistance comparable with that of alloy 825, but with higher strength obtained by age hardening.
Sverdrup Steel stocks alloy 925 round bars in a variety of sizes. The material is in accordance with NACE MR 0175. Click on the table to the right to see our stock selection
