Leading Supplier of Stainless Steel 403 

Specification of Grade 403 Stainless Steel also knowns as 
  • SUS403 | UNS S40300 | 1.4024 | AISI 403 

 

Properties of SUS403 Stainless Steel

SUS403 is the basic martensitic stainless steel; like most non-stainless steels it can be hardened by a “quench-and-temper” heat treatment. It contains a minimum of 11.5 per cent chromium, just sufficient to give corrosion resistance properties. It achieves maximum corrosion resistance when it has been hardened and tempered and then polished. SUS 403 is a general purpose grade often supplied in the hardened, but still machinable condition, for applications where high strength and moderate heat and corrosion resistance are required.

Corrosion Resistance of SS 403 

SS 403 resists dry atmosphere, fresh water, mild alkalies and acids, food, steam and hot gases. Must be hardened for maximum heat and corrosion resistance. Performance is best with a smooth surface finish. Less corrosion resistant than the austenitic grades and also less than 17% chromium ferritic alloys such as SUS430.
