What is the difference between AISI 304 and SS 304?

SUS304 (SUS meaning Steel Use Stainless) stainless steel austenite is typically known as the Japanese name for SS304 or AISI 304. The main difference between the two materials is not any physical property or feature, but how it is referenced in American and Japanese grades.

What’s the density of steel in kg m3?


Metal or Alloy Density – ρ – (kg/m3)
Stainless Steel 7480 – 8000
Steel 7850
Strontium 2640
Tantalium 16400

What is AISI in steel?

The coding system is known for its efficient classification of steels as it uses the standards from the American Iron and Steel Institute (A.I.S.I.) and the Society of Automotive Engineers (S.A.E.).

What are the properties of AISI 304 stainless steel?

The physical properties of AISI 304 stainless steel 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).

How to prevent weld decay in AISI 304 steel?

To prevent weld decay, please refer to heat treatment-stress relief, or recommend the use of ultra-low carbon stainless steel such as 304L, or stabilized stainless steel 321, 347. Filler metal for welding of AISI 304 stainless steel: E308, E309. When the service temperature is 370 °C (700 °F), E308L can be used.

What is the thermal conductivity of 304 stainless steel?

SS304 is widely used in the industrial use, furniture decoration, food and medical industry, etc. AISI 304L is the low carbon version of 304 stainless steel, Thermal conductivity (W/m·K) 16.3 (100 °C) (212 °F) 21.5 (500 °C) (932 °F) Mean coefficient of thermal expansion, (10-6 /K)

Is 304 stainless steel magnetic?

Type 304 stainless steel is not magnetic, but may be slightly magnetic after cold working.
