304 Stainless Steel Material Property Data Sheet

Better corrosion resistance than type 302.

304 stainless steel material property data sheet. 1 4301 aisi 304 is the standard austenitic chromium nickel stainless steel. Process equipment in mining chemical cryogenic food dairy and pharmaceutical industries. Types 302 304 304l and 305 stainless steels are variations of the 18 percent chromium 8 percent nickel austenitic alloy the most familiar and most frequently used alloy in the stainless steel family. These alloys may be considered for a wide variety of applications where one or more of the following properties are important.

The lower carbon content minimizes chromium carbide precipitation due to welding and its susceptibility to intergranular corrosion. Elastic modulus gpa mean coefficient of thermal expansion µm m c thermal conductivity w m k specific heat 0 100. Minimum mechanical properties for annealed types 302 304 304l and 305 austenitic stainless steel plate sheet and strip as required by astm specifications a 240 and asme specification sa 240 are shown below. Aisi 304 stainless steel uns s30400 is the most commonly used material in stainless steels and is usually purchased in an annealed or cold worked state.

We are creating other entries for more specific heat treatments and forms. Product data sheet stainless steel grades 304 304l 304h uns s30400 s30403 s30409 grade 304 is the most commonly used stainless steel. This matweb entry has typical values for specimens of unknown form heat treatment but appear to be annealed samples. T 300 series stainless steel.

High ductility excellent drawing forming and spinning properties. Because ss 304 contains 18 chromium cr and 8 nickel ni it s also known as 18 8 stainless steel. 304 stainless steel categories. Austenitic cr ni stainless steel.

304 stainless steel alloy data sheet industries supplied include. Physical properties of 304 grade stainless steel in the annealed condition. Type 304 has good processability weldability corrosion resistance heat resistance low temperature strength and mechanical properties good hot workability such as stamping and bending and no heat treatment hardening. Not resistant to intergranular corrosion.

Essentially non magnetic becomes slightly magnetic when cold worked. In some instances type 304 can be used in the as welded condition.
