Brand4539

Superaustenitic Stainless Steel

SINOXX 4539 is a low carbon high alloy austenitic stainless steel with high level of chromium and nickel. It is additionally alloyed with molybdenum and copper to provide added corrosion resistance in certain media. This grade is non-magnetic in all conditions and has excellent weldability and formability. Applications include, metallurgical processing – pickling equipment using sulfuric acid, oil and gas production, pulp and paper – processing equipment, seawater cooling equipment, and pharmaceutical industry.

Product advantages

Corrosion resistance

The high content of alloying elements in SINOXX 4539 gives the alloy very good resistance to uniform corrosion. The minimum value of PREN = 35 indicates the material has good resistance to seawater and other high chloride environments. The low carbon level of SINOXX 4539 provides resistance to intergranular corrosion in welded condition.
