PRODUCT DETAILS

SS 304 pipe is one of the foremost versatile and unremarkably used untarnished steels on the market. SS 304 pipe is the most traditional used alloy of this sort.

The chromium content in SS 304 pipe promotes the material's considerable resistance to the effects of corrosion and oxidation. The chrome steel alloy resists most oxidizing acids and can face up to standard oxidation although this doesn't mean that the steel won't tarnish over time.

The SS 304 pipe needs to be cold worked to generate higher tensile strength. For stainless steel sections which are welded heavily, post-weld annealing may be necessary to provide maximum corrosive resistance.
