304 stainless steel is the most widely used chromium-nickel stainless steel. It features good corrosion resistance, heat resistance, low temperature strength and mechanical properties. It also features good hot workability such as stamping and bending, free from heat treatment hardening (operating temperature -196 ° C ~ 800 ° C). Corrosion resistance is another advantage. However, if it is exposed to the industrial atmosphere or heavily polluted areas, it needs to be cleaned in time to avoid corrosion.
304 stainless steel is suitable for processing, storage and transportation of food. It is widely recognized as food grade stainless steel. It embodies good processing properties and weldability. In order to maintain the inherent corrosion resistance in stainless steel, the steel needs to contain more than 18% chromium and more than 8% nickel. 304 stainless steel is a grade of stainless steel produced in accordance with American ASTM standards. SUS 304 indicates the Japanese standard.
