Why Choose 436 Stainless Steel?
Good Corrosion Resistance
436 stainless steel has excellent resistance to atmospheric and fresh water corrosion, but its resistance to most salts and seawater is relatively weak. The addition of molybdenum has improved its corrosion resistance.
Heat Resistance
Type 436 has magnetic properties in both the annealed and cold-rolled tempered states, and can withstand an oxidizing environment of up to approximately 1400°F (760°C).
Good Weldability
436 stainless steel can be resistance welded, brazed, and welded, suitable for a variety of welding applications.
Formability
This material is easy to stretch and form, suitable for most hot-forming processes. The addition of niobium significantly reduces the occurrence of "roping" or "ridging" during the stretching and forming process.
FAQ about 436 Stainless Steel
436 vs 430 Stainless Steel
Relative to 430, 436 contains more molybdenum and niobium, giving it better corrosion resistance and weldability.
436 vs 434 Stainless Steel
436 Stainless Steel is a niobium-stabilized variant of 434 Stainless Steel, containing relatively more niobium (5C≦Nb≦0.80) than 436. Therefore, 436 Stainless Steel is widely referred to as the Nb version of 434, with the addition of niobium improving its resistance to ridging during the forming process.
