What is 304 stainless steel
304 stainless steel is a common material in stainless steel, containing more than 18% chromium and more than 8% nickel.
It is resistant to high temperatures of 800°C, has good processing performance and high toughness, and is widely used in industrial and furniture decoration industries and food and medicine. industry.
304 is a versatile stainless steel that is widely used to make equipment and parts that require good comprehensive properties (corrosion resistance and formability).
In order to maintain the inherent corrosion resistance of stainless steel, the steel must contain more than 18% chromium and more than 8% nickel.
304 stainless steel is a brand of stainless steel produced in accordance with American ASTM standards.
