Machinability:This steel grade is marked by a good machinability on machine tools and by an easy fragmentation of chips. Weldability:Due to the high sulphur and phophorus content free-cutting steels not destined to heat treatment are not generally recommended for welding.
11SMn30 Chemical Composition, 11SMn30 Mechanical It mainly introduce the chemical composition,mechanical properties, heat treatment, processing performance and performance standards about 11SMn30.For various specification of steel production and processing to provide the standard production,we have the professional experience for 11SMn30.We can also produce it according to the AISI, UNS, SAE, ASTM, DIN, JIS technical standard.
230M07/11sMn30 (EN1A) is a free machining low tensile carbon steel, characterised by excellent machinability, with reasonable strength and ductility.
EN 10277-3 Grade 11SMn30 cold drawn - Low Carbon Steel Free cutting steel 11SMn30 is unsuitable for heat-treatment and represents the standard sort for all bulk turned parts, also for parts of complicate full cross-section machining (e.g. spark plugs) and it replaces steel 9SMn28 (DIN 1651 :1988-04). 11SMn30 is suitable for thin-walled parts and low cold forming.
EN 10277-3 Grade 11SMn37 cold drawn - Low Carbon Steel Free cutting steel 11SMn37 is unsuitable for heat-treatment and is preferred steel 11SMn30 for higher requirements to machinability and surface appearance due to its higher S-content. For lower machinability demands it replaces the Pb-alloyed steel 11SMn30. Increased

FREE-CUTTING STEELSThe most common. The most common free-cutting steels are AVZ 11SMn30 and 11SMn37, AVP 11SMnPb30 and 11SMnPb37 steels and PR80 36SMnPb14. The latter is an free-cutting steel tempered with average carbon, discreet hardenability, high manganese and re-sulphured content, suitable for high-speed mechanical machining.
