Description

Leading Supplier of Stainless Steel - Grade 403 , SUS403 , AISI 403 , UNS S40300 , 1.4024

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 SUS403 , SS403 

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 Stainless Steel 403 , SUS403 

Typical applications include:
 

·         Bolts & Nults

·         Screws

·         Bushings

·         Pump and valve parts and shafts

·         Steam and gas turbine parts

·         Petroleum fractionating towers

·         Mine ladder rungs
