S235JR A36 Cold Drawn Steel Square Bar
SS400 steel is the most commonly used hot-rolled structural steel (formerly known as SS41) in Japan, and is called general structural rolled steel in JIS G3101. SS400 material is cheap and versatile, and plays an important role in construction, bridges, civil engineering and mechanical equipment structures. Its appearance includes round steel, flat steel (flat steel), square steel and hexagonal steel bars.
SS400 steel grade material is a kind of low carbon mild steel grade with good weldability and formability for a various applications.
Cold finished bars are produced from special bar quality hot rolled bars by cold drawing, turning, grinding, polishing, or by a combination of these methods.
Cold drawing increases a bar's yield strength and tensile strength, turning improves surface quality, grinding produces more precise tolerance ranges, and polishing further creates a smooth and attractive surface. Overall, cold finishing reduces the cross sectional area of the hot rolled bar. CF steel bars may be harder to work with than their hot rolled equivalents, but they make up for it with more accurate sizes, smooth surfaces, increased mechanical properties and machinability.

4.Advantages of our peeled 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 improve the Machinability and Productivity which Enables higher machining feeds, high tool life, yield & speeds and improved machined finish.
