This material is same as 430 stainless steel but with increased sulfur content so that it’s machinability is improved. It still has moderate ductility though this alloy does not form easily because of sulfur content. It’s a free machining version of grade SS 430. It is non- heat treatable, has moderate strength and is also corrosion resistance.
