Are considering using 201SS instead of 304SS for the fabrication of miscellaneous boxes attached to trucks. Cost is the reason. Are there any fabrication/ welding/ polishing considerations. I know that 201SS is alittle stronger THAT 304ss  as the yield is higher so the enlongation is less consequently the fabrication ( bending ) might be slightly different. How about the welding? Seems 308 filler is still recommended. Any hot cracking or other issues with this change that anybody is aware of?
