Product Description

Product Description

ASTM A312 Tp321 / S32168 /12X18h10t Seamless Stainless Steel Pipe Tube

The characteristics of 321 stainless steel seamless pipe mainly include wear resistance, high temperature resistance, creep resistance, excellent high temperature stress fracture performance, and high temperature creep resistance.

321 stainless steel is a Ni-Cr-Ti austenitic stainless steel with excellent wear resistance, high temperature resistance, and creep resistance, which makes it very suitable for manufacturing wear-resistant acid containers, lining of wear-resistant equipment, and conveying pipelines. In addition, 321 stainless steel exhibits excellent corrosion resistance in the atmosphere and is widely used in industries such as petrochemicals, power, bridges, and automobiles. Its excellent performance demonstrates significant superiority in the use of materials for high-pressure and high-strength mechanical structures.

The characteristics of 321 stainless steel seamless pipe make it a high-performance material that can maintain stable performance in harsh environments, ensuring long-term stable operation of equipment and systems. Whether used for high-pressure steam boiler pipelines or other applications that require high temperature and pressure resistance, 321 stainless steel seamless pipes can provide reliable support and protection.

Advantages:

  • Strength and Durability: excellent strength and durability, suitable for demanding environments.
  • Corrosion Resistance: good resistance to a wide range of corrosive substances.
  • Seamless Construction: eliminate the risk of weak points associated with welded seams, improving reliability.
  • Smooth Interior Surface: smooth interior surface, reducing friction and pressure drop in fluid flow.
