Comparison Of Austenitic Stainless Steel Seamless Tube

  • We often see all kinds of seamless tubes around us, including the austenitic stainless steel seamless tube. Today we will talk about the difference between the Austenitic Stainless Steel Seamless Tube and other seamless tubes.

    The yield strength of austenitic stainless steel seamless tube is twice that of austenitic stainless steel. This feature enables designers to reduce weight when designing products, making this alloy more cost-effective than 316 and 317L. This alloy is especially suitable for the temperature range of -50°F/+600°F. For applications beyond this temperature range, this alloy can also be considered, but there are some limitations, especially when applied to welded structures.

    Compared with Ferritic Stainless Steel Seamless Pipe and Tube and martensitic stainless steel seamless tube, austenitic stainless steel seamless tube has high toughness, low brittle transition temperature, significantly improved intergranular corrosion resistance and welding performance, while retaining ferrite Body stainless steel has some characteristics such as high thermal conductivity, low linear expansion coefficient, and superplasticity. Compared with austenitic stainless steel, its strength is higher, especially the yield strength is significantly improved, and it is resistant to intergranular corrosion and stress corrosion. And corrosion fatigue and other properties have been significantly improved.
