Bright annealed stainless steel tube

What is Bright Annealed Stainless Steel Tube and why annealing is performed?

Bright annealing is a heat treatment process performed in a controlled atmosphere. It helps to achieve a bright, polished and reflective surface finish on the stainless steel tube. Bright Annealed Stainless Steel Tube comes with the following features:

  • They have a smooth and mirror like finish.
  • The process helps in passivating the tube surface, forming a thin, protective oxide layer. It improves oxidation resistance and reduces the risk of corrosion.
  • The process also helps in achieving a higher level of cleanliness and reduces the risk of contamination in sensitive applications.

Stainless Steel Bright Annealed Finish of Alloying Elements

Alloying elements Effect on the properties
Chromium Boosts resistance against oxidation and corrosion. improves wear resistance and hardenability. strengthens at high temperatures.
Molybdenum Improves wear resistance, hardenability, and high temperature hardness. amplifies the impact of additional mitigating factors. Remove the steel's brittle temper. strengthens at high temperatures.
Nickel Improves hardenability. increases resilience. boosts impact resistance in cold weather.
Cobalt Raises wear resistance and heat.
Titanium Strongest former for carbide. added to stainless steel to stop chromium carbide from precipitating.
Manganese Improves hardenability. When combined with sulfur, its negative effects are lessened.
Vanadium Improves wear resistance, hardenability, and high temperature hardness. increases resilience to fatigue.
Aluminum Forms nitride when steels are nitrided.produces a casting with fine grain size. takes oxygen out of the melting steel.
Silicon Eliminates oxygen while producing steel.increases resilience. Boosts the capacity for hardness.
Boron Improves hardenability. yields a fine grain size.
Tungsten Raises the hardness at high temperatures. refines the size of the grain.
