ASTM 1117 1040 Steel Round Bar Yield Strength High 16mm 18mm 19mm 20mm 25mm 28mm
ASTM1117 Free Cutting Steel Bar Bright Round Bar 2.5m-6m ASTM A29/A29M-2015
1117 is the American standard ASTM standard free cutting steel. Good precision, easy cutting, can greatly improve the service life of the tool, reduce the processing time, machinability significantly improve efficiency. 1117 free-cutting steel by increasing the sulfur and manganese content in the steel, forming a large number of manganese sulfide inclusions, iron filings are easy to break when cutting, can improve the surface quality of parts, and can be processed at a faster speed and deeper feed volume, thereby improving production efficiency and saving production costs.
