What is the distinguish between 430 and 304 stainless steel

- Apr 12, 2018 -

The distinguish between 430 stainless steel and 304 stainless steel are as follows:


  1. Corrosion resistance: 430 stainless steel chromium containing 16.00-18.00%, basically no nickel metal, 304 stainless steel chromium nickel metal, so 430 stainless steel corrosion resistance of no 304 stainless steel.


2. Stable performance: 430 stainless steel is ferrite form, 304 stainless steel is austenitic morphology, 304 stainless steel is more stable than 430 stainless steel.


3. Toughness: 304 stainless steel has strong toughness, stronger than that of 430 stainless steel.


4. Thermal conductivity: 430 stainless steel ferrite than 304 stainless steel austenite thermal conductivity is good.


The 304 is austenite type, 430 is martensite or ferrite type. The austenite type is nonmagnetic or weak magnetic, and martensite or ferrite are magnetic.
