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.
