Material of Stainless Steel Tube SS-316L Type Seamless Mirror Polished 32 mm Dia Wall Thickness of 3 mm

Stainless steel seamless pipe is a long strip of steel with a hollow section and no seams around it. The thicker the wall thickness of the product, the more economical and practical it is, and the thinner the wall thickness, the higher its processing cost will be.
The process of this product determines its limited performance. Generally, seamless steel pipes have low precision: uneven wall thickness, low brightness inside and outside the tube, high cost of cutting to length, and pits and black spots on the inside and outside are not easy to remove; its detection and Shaping must be handled offline. Therefore, it embodies its superiority in terms of high pressure, high strength, and mechanical structural materials.

AISI 316L Stainless Steel (UNS S31603)

AISI 316L stainless steel is a modified ultra-low carbon Cr-Ni-Mo series austenitic stainless steel based on AISI 316. It is recommended for parts that cannot be annealed after welding in certain corrosive environments. The addition of molybdenum can provide pitting resistance in phosphoric acid and acetic acid and dilute chloride solutions and corrosion resistance in sulfurous acid. SS316L is resistant to carbide precipitation in the temperature range of 425-870 °C (800-1600 °F), so normal welding can be performed without reducing corrosion resistance. However, when it is heated and kept in the sensitization temperature range for a long time during use, a large amount of carbides will precipitate, so it is usually recommended to use it below 425 °C (800 °F).

Type 316L Stainless Steel Properties

Type 316L stainless steel density is 0.289 lb/in3 (8.0 g/cm3); melting point is 1375-1400 °C (2500-2550 °F); 0.2% yield strength is minimum 25 ksi (170 MPa) in annealed and hot finished condition, minimum 45 ksi (310 MPa) in annealed and cold finished condition; Minimum tensile strength is 70 ksi (485 MPa) in annealed and hot finished condition, ≥ 90 ksi (620 MPa) in annealed and cold finished condition; Maximum Brinell hardness is 217 HB, Maximum Rockwell hardness is 90 HRBW; Thermal conductivity is 12.1 W/m·K at 20 °C (68 °F), 16.3 W/m·K at 100 °C (212 °F).
