Seamless Stainless Steel TP310 Pipe (UNS S31000 / 1.4841) High-Temperature Heat-Resistant Austenitic Stainless Steel Pipe
What is TP310 Seamless Stainless Steel Pipe?
SeamlessTP310 stainless steel pipe (UNS S31000 / W.Nr. 1.4841) is a high-alloy austenitic stainless steel specifically designed for extreme high-temperature service and oxidation resistance.
Manufactured using a seamless process (hot piercing + cold finishing), the pipe provides:
- Uniform metallurgical structure
- No weld seam defects
- Superior high-temperature strength
- Excellent resistance to thermal cycling
The TP310 grade is characterized by:
- Chromium (Cr): ~25%
- Nickel (Ni): ~20%
This Cr-Ni combination forms a stable protective oxide layer, allowing continuous service at temperatures up to:
1150°C (2100°F)
Compared with TP304 and TP316, TP310 offers significantly better oxidation resistance and creep strength, making it the preferred material for high-heat industrial applications.
