erw welded pipes

Used in Furniture Industry, Salvage Industry, Tourism Industry, Fitness Apparatus Industry and Municipal Construction Projects.

316 / 316L is not hardenable by heat treatment. Cold working increases tensile strength and hardness.
Annealing range is between 1850° and 2050°F.

The welded pipes welding is still a important point even if the steel materials has been annealed. Client use the annealed pipe to bend and shape.
