Re: [MW:14253] Re: Welding C45 (1045)

I checked out your chemical composition and it has a chemical
composition of carbon.12/chromium 29.3/Nickel 9.4/Manganese1.8.If you
know your metals then this would be categorized as an Austernetic
stainless steel.Different countries have different electrodes but the
chemical compositions are basically the same......so in my experience
iv been in different countries and British standard rods and American
standard rods have different code names but the chemicals are the same
...but thank you for informing me of the Korean version Electrode.
