Stainless steel grade 439 is capable of being made into complex shapes such as tubular manifolds and exhaust system components, where temperatures tend to go beyond the oxidation limit of grade 409 steel. It is also preferred where wet corrosion resistance especially to chlorides is needed.
Stainless steel grade 439 has good weldability, brightness, and pitting corrosion resistance. It polishes well, and is good for deep drawing.

Applications
Stainless steel grade 439 is applied in areas that require oxidation and corrosion resistance. It is also widely used in catering equipment.
In 2016, it signed a strategic cooperation agreement with major domestic stainless steel factories for the sales of medium and heavy plates and special steel products, which also enabled the company to have new and brighter sales varieties. At the same time, it provides one-stop service for cutting, cutting, forming and and surface processing of stainless steel.
