4404SFree Machining Austenitic Stainless Steel
SINOXX 4404S is a chromium-nickel-molybdenum austenitic stainless steel with an addition of sulfur. It has good strength and creep resistance, as well as excellent mechanical properties and corrosion resistance. The added sulfur forms manganese sulfides, which offer higher machining speeds and improve cutting tool life. These non-metallic inclusions can also provide a source of solid lubricant to the tool/workpiece interface. Typical applications include chemical equipment, pressure vessels, medical equipment, heat exchangers, and marine applications.

Product advantages
Corrosion resistance
SINOXX 4404S has comparable corrosion resistance to SINOXX 4404. It has excellent corrosion resistance in natural atmospheres, like rural and urban atmospheres, and even in moderate concentrations of chlorides and acids. SINOXX 4404S effectively resists intergranular corrosion even after welding. The optimum corrosion resistance is achieved on a surface free from residual machining oils or foreign particles.
Manufacture
SINOXX 4404S is made by SIJ Acroni.
