The following tables give SS 304 stainless steel properties and specifications (datasheet) including chemical composition, physical and mechanical properties, heat treatment, corrosion resistance, machinability and machining, welding, etc.
The following datasheet and specification show SS 304 stainless steel properties including physical properties and mechanical properties. Chemical Composition Type 304 grade stainless steel composition is given in table below.
Material Notes: Austenitic Cr-Ni stainless steel. Better corrosion resistance than Type 302. High ductility, excellent drawing, forming, and spinning properties. Essentially non-magnetic, becomes slightly magnetic when cold worked.
Type 304 is the most versatile and widely used stainless steel. 304 stainless steel is an austenitic grade that can be severely deep drawn. The properties, applications and fabrication details are provided for 304 stainless steel.
Corrosion resistance as for 304. High carbon gives improved high temperature strength. Excellent resistance to corrosion, particularly attack by hot sulphur compounds in oxidising
Note: The chart below gives typical mechanical characteristics for selected stainless steel properties. For all critical applications, verify to the applicable industry or requisite material / steel standard.
304 stainless steel physical properties are listed in the table below such as density, melting point, specific heat, electrical resistivity, elastic modulus (modulus of elasticity), thermal conductivity, and coefficient of thermal expansion (CTE), etc.
Table 1 shows some basic mechanical properties of 304 steel. The following section will briefly detail each of these parameters, and show how they are pertinent to the working properties of 304 steel.
In order to assist the reader in this selection, Euro Inox makes the following tables of technical properties available: Chemical composition of stainless steels (flat products) Mechanical properties of stainless steels (flat products) Physical properties of stainless steels.
304 stainless steel has good heat resistance, with intermittent service up to 870°C and continuous service up to 925°C. However, continuous use in the temperature range of 425°C – 860°C is not recommended due to the risk of carbide precipitation.
