Why Choose Stainless Steel 446 Buttweld Fitting?

Stainless Steel 446 is a high chromium ferritic stainless steel, the chromium content of which is more than 23 percent, coats itself into a stable oxide layer to resist oxidation and high temperature corrosion. In contrast to austenitic grades, SS 446 has low thermal expansion, high creep strength, and high stress corrosion cracking resistance, which is why this alloy is recommended in high temperatures in pipelines, industrial setups where the environment is harsh.

It has ferritic structure, which makes it weldable, easy to fabricate and stable in its dimensions, but not subject to surface scaling and high temperature corrosion. This predisposes SS 446 Buttweld Fittings to be an option in high-performance pipelines in the chemical, petrochemical, power generation and offshore line that requires a high level of mechanical strength and corrosion resistance.
