Brand4307S

Free Machining Austenitic Stainless Steel

SINOXX 4307S is a chromium-nickel austenitic stainless steel with the addition of sulphur. Due to the added sulphur in SINOXX 4307S, manganese sulphides are formed, which can offer higher machining speeds and improve cutting tool life. These non-metallic inclusions can provide a source of solid lubricant to the tool/workpiece interface.

It is commonly used in the automotive industry, general construction, flanges and fittings, processing equipment, and more.

Product advantages

Corrosion resistance

SINOXX 4307S is not recommended for use in marine environments and highly oxidizing chemical environments. Special care should be taken when using SINOXX 4307S in acidic or chloride environments where corrosion by pitting and cracking may occur.
The use of SINOXX 4307S is compatible with all types of fluids, lubricants and grease applied in industry and machining. Optimum corrosion resistance is achieved with a surface free from residual machining oils or foreign particles.
