Good corrosion resistance against water, but never used in presence of sulfuric acid in any concentration
1.4301 is machinability is very low but 1.4305 is a very good machinability 1.4301 is having very good weldability but 1.4305 is not good for welding
1.4307 is a low carbon version of 1.4301, with improved weldability
