314 stainless steel is an alloy of iron, nickel and chromium. It offers superior corrosion resistance and high-temperature strength compared to other steel alloys. 314 stainless steel is often used in food processing equipment, chemical tanks, heat exchangers and industrial appliances due to its excellent performance characteristics.
TP304 Seamless Stainless Steel Tube are a highly versatile and corrosion-resistant tubing solution used widely across construction, petrochemical, and automotive sectors. ① STANDARD: ASTM A213/ ASTM A312/ ASTM A249/ ASTM A269/ GOST 9940 /GOST 9941...② OD RANGE : 6-257MM③ THICKNESS RANGE: 1-35 MM
Seamless 654SMO Super Stainless Steel Tube UNS S32654, W. Nr. 1.4652) is a high-performance super austenitic stainless steel alloy, often classified as a "super stainless steel" due to its exceptional corrosion resistance and mechanical strength. Developed for the most demanding environments, it features unusually high levels of chromium (24%), molybdenum (7-8%), nickel (23%), and nitrogen (0.45-0.55%), enabling pitting resistance equivalent number (PREN) values exceeding 50—comparable to top nickel-based alloys like Hastelloy. The seamless design ensures superior integrity for high-pressure, high-temperature, and corrosive applications, avoiding weld-related vulnerabilities. It is twice as strong as conventional austenitic grades like 304 or 316 while maintaining excellent ductility and toughness.① STANDARD: ASTM A312/EN10216-5/GBT14976.② OD RANGE : 6.35-257MM③ THICKNESS RANGE: 0.89-35MM
