Quick Detail

As the basic steel of the austenitic series, 304 stainless steel plate has excellent corrosion resistance, heat resistance, low temperature strength and mechanical properties. It does not harden after heat treatment and is almost non-magnetic. 304 stainless steel plates are widely used in industrial transportation pipelines such as petroleum, chemicals, medical, food, heat exchangers, etc. In addition, when the torsional strength and bending strength are the same, it is lighter than the weight, so it is also widely used in engineering structures.
