4140 SCM440 42CrMo4 Cold Drawn Steel Bar Round/Square/Hexagon Bar
1018 grade steel is one of the most widely used grades of steel as it is applicable for many different uses and comes at an affordable price. Our 1018 hex bars have a low carbon and medium manganese composition, which makes 1018 better suited for applications that do not require the strength that high carbon steel provides.1.Processing for Cold Drawn Steel Bars
hot rolled bars/wire rods - (spheroidizing annealed for alloy steel/bearing steel) - pickling - cleaning - saponifing - cold drawn - (softening annealed for alloy steel/bearing steel) - cutting - bundling - packing - finished products2.The advantages of Cold Drawn Steel Bars
1.It can remove the Size and Section which provides Tighter tolerances which Reduces machining losses.
2.It can remove the Steel Surface Finish which Reduces surface machining & improves quality.
3.It can remove the Straightness which Facilitates automatic bar feeding in CNC.
4.It can increase the Mechanical Properties which Can reduce the need for hardening.
5.It can improve the Machinability and Productivity which Enables higher machining feeds, high tool life, yield & speeds and improved machined finish.3.steel chemical composition
