SS Round Bar Drawn EN1.4301/4307
Austenitic steels with designations 1.4301 and 1.4307 are the commonest stainless types and contain about 18% chromium and 9% nickel. The difference between the two grades is that in 1.4301, the maximum allowed carbon content is higher than for 1.4307 which can mean that 1.4301 has marginally higher strength. In practice, the difference in carbon between 1.4301 and 1.4307 is often of little significance. However, if welding is to be performed, 1.4307 is the preferred alternative since corrosion resistance in the vicinity of the weld could be impaired for 1.4301.
