ASTM A358 CL1 TP316L,Stainless Steel Welded Pipe,High-Temperature Service
Overview
ASTM A358: The "ASTM" stands for the American Society for Testing and Materials, which sets standards for various materials and products. A358 specifically pertains to electric-fusion-welded (EFW) stainless steel pipes for corrosive or high-temperature applications.
CL1: CL1 refers to the Class 1 designation within the A358 standard. Class 1 encompasses pipes that are double-welded, using the full-penetration welding process. These welded tubes are capable of withstanding high internal pressures.
TP316L: TP316L is the specific grade of stainless steel used for these welded tubes. TP316L is a low carbon version of TP316 stainless steel, offering improved corrosion resistance, particularly in environments with sensitization potential, such as in welding applications.
