Product Description

S20C cold drawn steel round bar

 

Cold rolled S20C steel bar is a low carbon steel grade with good weldability and formability for a various applications. S20C Cold Drawn Steel Bar are usually used in many industries like automotive, agriculture, construction and motorcycle.

 

Cold finished steel is cold drawn or cold rolled by hot rolled steel. It is typically produced as turned bars or cold drawn bars. Cold Drawn Steel bar is accomplished by cold drawing a bar through a mould. By cold drawing, the dimensional tolerances, the straightness and the surface roughness of the bars will be improved. In the meanwhile, the mechanical properties will be enhanced, too.

 

S20C cold drawn steel bar we supply includes following advantages:

Sizes

Wide range from 14mm to 100mm

Tolerances

Precision to h9, h10, h11 or even small to 0.02mm

Roundness

75% of diameter tolerance

Straightness

Good straightness to 0.5mm/m

Surface roughness

Smooth to 0.8um

Mechanical properties

Yield strength and tensile strength can be improved

Machining

Suitable for machining and welding

Company Overview

Shandong Le Ren Special Steel CO., Ltd. owns three factories to produce all kinds of steel rod, steel bar and finished steel products. Among three factories, one is to produce steel bars such as annealed, normalized and quenched and tempered steel bar and pipe, cold drawn, peeled, ground and polished steel bar etc; one is to produce threaded or knurled steel rod and steel bar; another one is to do steel bar, steel rods or steel pipe machining. 


In the tactories, we have complete and advanced production, inspection and testing facilities such as shot blasting machines, cold drawing machines,straightening machines, annealing furnace, quenching and tempering furnaces, threading machines, cnc machines, welding machines etc, and inspections and testing facilities to inspect dimension tolernaces, corner radius, length, straightness, surface roughness, mechanical properties, AKV, UT testing, Eddy testing and MPI testing etc. All of these, including more than twenty years production and exporting experiences, we can supply you good quality products and services.
