12Х18Н10Т 321 Stainless Steel Tube is a titanium-stabilized austenitic stainless steel tube. Its core characteristic is the addition of titanium (Ti), which significantly outperforms 304 stainless steel tubes in terms of resistance to intergranular corrosion and high-temperature performance. It is suitable for medium-to-high temperature corrosion environments ranging from 427 to 900℃.
2205 Stainless Steel Tube is a metal tubing composed of two phases: ferritic (45-55%) and austenitic (55-45%). Its chemical composition includes 22% chromium, 5% nickel, 3% molybdenum, and 0.18% nitrogen.
2205 Stainless Steel Tube exhibits excellent mechanical properties, corrosion resistance, and good weldability, making it widely used in the oil and gas industry, marine engineering, and chemical industry.
2205 Stainless Steel Tube conforms to standards such as ASTM A312 and EN 1.4462, with an outer diameter range of 6-114 mm. Surface treatments include pickling or polishing.
304 Stainless Steel Tube is the stainless steel pipe grade produced according to US ASTM standards. It corresponds to the Chinese grade 0Cr19Ni9 (formerly 0Cr18Ni9) and the German standard DIN2462. Due to its excellent corrosion resistance and good mechanical properties, 304 Stainless Steel Tube is widely used in food processing equipment, chemical containers, nuclear power industry facilities, and machinery manufacturing.
316L Stainless Steel Tube is a commonly used stainless steel pipe, primarily used in industrial pipelines for the petroleum, chemical, medical, food, light industry, and mechanical instrumentation industries, as well as in mechanical structural components. Its light weight, while maintaining comparable bending and torsional strength, makes it widely used in the manufacture of mechanical parts and engineering structures.
316Ti Stainless Steel Tube is an austenitic stainless steel tube made by adding titanium to SUS316 steel. Its Chinese designation is 0Cr18Ni12Mo2Ti. Its chemical composition includes 10.0% to 14.0% nickel and 2.00% to 3.00% molybdenum, conforming to ASTM A312 and ASTM A213 standards.
Stainless steel tubes are divided into two categories: seamless tubes and welded pipes according to production methods. Seamless steel pipes can be divided into hot-rolled pipes, cold-rolled tube, cold-drawn pipes and extruded pipes. Cold-drawn and cold-rolled pipes are the secondary processes of steel pipes. Processing; welded pipes are divided into straight seam welded pipes and spiral welded tubes.
