EN 10277-3 Grade 11SMnPb30 as rolled and turned (+SH)
EN 10277-3 Grade 11SMnPb30 as rolled and turned (+SH) introduction
Free cutting steel 11SMnPb30 is unsuitable for heat-treatment and is preferred steel 11SMn30 for higher requirements to machinability and surface appearance. 11SMnPb30 shows a lower cracking sensitivity compared to steel with a higher S-content (11SMn37, 11SMnPb37). Application for bulk parts in car industry as well as in apparatus and equipment engineering. As a bright steel product it is used in the form of bars, bright, straight, in various conditions (see DIN EN 10277 : 1999-10).
