Casting machine raw material 304 stainless steel pipe introdution:
1. A high-alloy steel that resists corrosion in air or chemically corrosive media. The 304 stainless steel tube has an aesthetically pleasing surface and good corrosion resistance. It does not have to undergo surface treatment such as plating to give full play to the surface properties inherent in stainless steel. A kind of steel in many ways.
2. 304 stainless steel tubes are commonly referred to as stainless steel. Representative properties include high-alloy steels such as 13 chrome steel and 18-8 chrome nickel steel. From the perspective of metallography, because stainless steel contains chromium and the surface forms a very thin chromium film, this film is isolated from the intrusion of oxygen in the steel to resist corrosion. In order to maintain the corrosion resistance inherent in stainless steel, steel must contain more than 12% chromium. 304 is a versatile stainless steel that is widely used to make equipment and parts that require good overall performance (corrosion resistance and formability). 304 stainless steel is a grade of stainless steel produced in accordance with American ASTM standards. 304 is equivalent to China's 0Cr19Ni9 (0Cr18Ni9) stainless steel.
