303 Stainless Steel Material Property Data Sheet

It also has good oxidation resistance in continuous service to 870 c.

303 stainless steel material property data sheet. 304 304l stainless steel 1 type 304 stainless steel is a variation of the base 18 8 grade with a higher chromium and lower carbon content. Grade 303 is the most readily machineable of all the austenitic grades of stainless steel. 303 stainless steel annealed bar categories. It also has good oxidation resistance in continuous service to 870 c.

Alloy 303 is resistant to mildly corrosive environments. Grade 303 should not be exposed to marine or other similar environments to prevent rapid pitting corrosion. However the sulfur addition does lower alloy 303 s corrosion resistance to below that of alloy 304. To see matweb s complete data sheet for this material including material property data metal compositions material suppliers etc.

This page displays only the text of a material data sheet. Its corrosion resistance is superior to 416 another free machining grade but is somewhat inferior to other 400 series stainless steels which do not contain higher sulfur levels. The machineable nature of grade 303 is due to the presence of sulphur in the steel composition. This however is not recommended as 303 is sensitive to carbide precipitation with continuous use at 425 860 c.

Its sulphide inclusions act as pit initiation sites meaning it provides a lot less resistance than 304. 303 stainless steel has good resistance to oxidation when intermittently exposed to temperatures up to 760 c. Grade 303 stainless steel has good resistance to oxidation when intermittently exposed to temperature up to 760 c temperatures. Choose from our selection of 303 stainless steel including over 600 products in a wide range of styles and sizes.

The lower carbon content minimizes chromium carbide precipitation due to welding and its susceptibility to intergranular corrosion. Aisi 303 stainless steel physical properties are given in the following lists including density thermal expansion elastic modulus thermal conductivity specific heat capacity and electrical resistance. In stock and ready to ship. Whilst the sulphur improves machining it also causes a decrease in the corrosion resistance and a slight lowering of the toughness.

However the alloy s corrosion resistance is inferior to 304 in most applications. In some instances type 304 can be used in the as welded condition. The corrosion resistance of type 303 is lower than that for 304.
