STAINLESS STEEL 304
Stainless steel AINSI 304 (1.4301) is an austenitic steel, its chemical resistance is very high, its ductility is comparable to that of copper or brass, it is non-magnetic, and also its mechanical characteristics are high. The contents of addition elements turn around 18% chromium and 10% nickel. The carbon content is very low and improved stability by elements such as titanium or niobium. He is very bad conductor of heat. Folding by press or wheel does not show of special difficulty. Stamping requires machines twice as powerful than those that serve for mild steel. The best way to weld steels
stainless, is welding with austenitic filler metal. all traditional processes
are usable, arc welding with coated electrode, submerged arc welding,
processes in an inert atmosphere such as TIG and MIG, plasma welding. The flow of argon or helium around the electric arc prevents the oxidation of the melt as well as during the transfer of the filler metal.
In many cases soap cleaning is enough. There are detergents
appropriate but ultimately nothing beats nitric acid which removes deposits and
leaves a very well passivated surface.
