Stainless steel solution annealed tube

What are Solution Annealing stainless steel tubes?

Solution annealing treats the tubes for recrystallizing the work-hardened austenitic stainless steel. The process also helps to draw chromium carbides. Annealing also helps to alter its metallic structure, which in turn, changes the mechanical and electrical properties of the material.

What is the purpose of solution annealing of stainless steel tubes?

Solution Annealing Stainless Steel Tubes manufacturer in India performs this procedure after cold working or welding the tubes. The ss may undergo strain hardening and form grain boundaries during cold working or welding, which can affect its performance and corrosion resistance. The solution annealing process removes strain hardening and restores the ductility, toughness and corrosion resistance properties.

What is solution annealing procedure for stainless steel pipe?

To get Solution Annealed Stainless Steel Pipe, heat treatment is done on austenitic stainless steel. They are soaked in temperature not less than 1038 degrees C for a considerable time so that the carbon in the steel would become a solid solution. The material then gets quenched rapidly by water or cool air. This helps to prevent the reprecipitation of carbon.

What is difference between annealing and solution annealing?

The primary difference between annealing and solution annealing lies in their purpose. Annealing is done to soften the material. The Solution Annealing Stainless Steel Heat Exchanger Tubes procedure helps to gain desired properties in the material, which include increased strength, impact resistance, hardness, etc

Advantages of SS solution annealed tubes

  • The Solution Annealed 316 Stainless Steel instrumentation tubing comes with enhanced corrosion resistance.
  • The solution annealing process puts carbide into the microstructure of the solution.
  • This process improves the quality of the ss and results in uniform and stress free mechanical properties.
