ASTM A213 Alloy Steel Pipe specification

ASTM A213 Alloy Steel Pipe

ASTM A213 is a widely recognized standard that specifies seamless ferritic and austenitic steel pipes used in high-temperature applications, such as boiler tubes, heat exchanger tubes, and other critical components. The standard includes various grades like T5, TP304, and others. Grades marked with an "H" typically exhibit enhanced creep rupture strength compared to their non-H counterparts. ASME SA213 seamless pipes are specifically chromium-molybdenum steel tubes containing chromium and molybdenum elements, making them ideal for high-temperature environments.

CSC STEEL is a leading manufacturer and supplier of ASTM A213 low alloy steel pipes available in multiple grades and sizes. We offer a wide range of ASTM A213 seamless alloy steel pipes, including T2, T11, T12, T22, T91, and T92, in various conditions such as annealed and pickled, bright annealed, finished, and polished, according to customer specifications.

Nylon Resin

The material is particularly suitable for applications with 50-60% glass fiber reinforcement, delivering exceptional strength and stiffness. A unique characteristic is its ability to maintain a smooth, resin-rich surface with high gloss finish even with high glass fiber content, making it ideal for:
  • Painting
  • Metal coating
  • Natural reflective shell applications
