Product Description

We are keep Stocks in 309/309S which is a highly authenticate CR-NI stainless steel used for its excellent oxidation resistance, High temperature and creep resistance.  SS 309 except for a Low Carbon Content that minimizes carbide precipitation and improves weld ability.It is tough and ductile,and can be readily fabricated and machined

309S is the low-carbon version of 309,and is recommended for applications where sensitisation, and subsequent corrosion by high temperature gases or condensates during shutdown may pose a problem. They are essential Non-Magnetic  as annealed  & become slightly magnetic when  cold worked. 309 is manufactured to ASTM A 167 and  309S to ASTM A240 specifications.
