3000MM TP304 Stainless Steel Seamless Tube ASTM A213 for Food Industry
YUHONG 304 Stainless Steel Seamless Tube is widely used in chemical, food, pharmaceutical and other industries for its excellent corrosion resistance and strength. Its composition is mainly chromium and nickel, which ensures good resistance to high temperature and oxidation. Through the seamless machining process, the internal and external surfaces of 304 stainless steel pipe are smooth, which reduces the possibility of harboring bacteria and is easy to clean. In addition, 304 stainless steel seamless pipe has stable performance in terms of pressure and levelness, which makes it an indispensable and important material in modern industry.
