SUS403 Stainless Steel | SUS403 | SS403 : Top Choice in Malaysia, Selangor, Kuala Lumpur (KL), Klang E STEEL SDN. BHD.

Description

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.

Stainless Steel 403 (1.4024) 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. SUS403 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 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
