We are the Leading Supplier of Stainless Steel SUS403.
Grade 403 Stainless Steel (SS403) is the basic martensitic stainless steel; like most non-stainless steels it can be hardened by a “quench-and-temper” heat treatment.
We supply and export to Singapore , Indonesia , Brunei and other ASEAN Countries.
Our specialty is to provide wide range of stainless steel with no minimum order (MOQ).
E Steel supply Stainless Steel 403 (SUS403, SS403) Round Bars and Rods, Stainless Steel 403 (SUS403, SS403) Plates and Sheets.

Corrosion Resistance of AISI 403 Stainless Steel
SUS403 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.
Applications of SS403 Stainless Steel
Typical applications include:· Bolts & Nults
· Screws
· Bushings
· Pump and valve parts and shafts
· Steam and gas turbine parts
· Petroleum fractionating towers
· Mine ladder rungs
