Seamless Stainless Steel Tubing ,321 ,X6CrNiTi18-10 ,1.4541, Round
Steel Tubing 5 inch 6 inch 7 inch
Zheheng steel deal with 321 ,X6CrNiTi18-10 ,1.4541, 321 Seamless Stainless Steel
Tubing has different names in different standards, the European standard
is 1.4541, the chemical conforms to X6CrNiTi18-10 , and in the American standard we are generally called ,321 ,
referred to as ,321 Seamless Stainless Steel Tubing. Zheheng steel is a Chinese company specializing in the production
of various 5 inch 6 inch 7 inchh , 321 austenitic stainless steel
seamless tubing. The products are strictly in accordance with the American
standard. European standard, Japanese standard implementation.
High-quality carbon structural steel, alloy structural steel and
stainless steel heat-resistant steel seamless steel tubing used for
steam boiler tubing such as high pressure and above. These boiler
tubes are often operated under high temperature and high pressure,
and pipes are exposed to high temperature smoke. Oxidation and
corrosion occur under the action of gas and water vapor. Therefore,
the steel pipe is required to have high durability, high oxidation
resistance, good structural stability, and hydraulic pillar tubing.
