C15 Round Bars are low-carbon, non-alloy steel bars valued for their good machinability, formability, toughness and suitability for case-hardening applications. C15 is commonly identified as material number 1.0401 and is associated with low-carbon case-hardening steel grades used for engineering components requiring a comparatively soft and ductile core with a harder surface after suitable carburizing and heat treatment. Jineshwar Steels supplies C15 Round Bars for engineering, automotive, machinery, fabrication and general industrial requirements in different diameters, lengths and delivery conditions. As a professional C15 Round Bars manufacturer, the company focuses on dimensional consistency, material traceability and application-oriented supply. The grade is particularly useful where components require reliable machining before surface hardening and where excessive core hardness is not desired.

The chemical balance of C15 steel makes it a practical material for components that require a combination of formability and case-hardening capability. Typical C15 chemistry includes approximately 0.12–0.18% carbon, controlled silicon and manganese, with phosphorus and sulfur maintained within specified limits depending on the applicable standard and product form. The low carbon content helps retain a relatively ductile core while allowing the surface to be enriched through carburizing. Jineshwar Steels can supply C15 Round Bars according to the required specification, size, surface condition and testing requirements. Buyers looking for a dependable C15 Round Bars supplier can specify diameter, quantity, length, standard, heat-treatment condition and inspection requirements while requesting a commercial quotation.

C15 Round Bars Latest Price List

C15 Round Bars are suitable for machining a broad range of small and medium-sized engineering components. Depending on the final component design and heat-treatment route, the material can be used for pins, bushes, shafts, sleeves, bolts, joints, couplings, lightly loaded gears and other machine parts. C15 is not normally selected simply because it has a high bulk strength; its principal advantage is the balance between machinability, ductility and its ability to develop a harder wear-resistant surface through suitable case-hardening treatment. This makes it useful where the working surface requires improved wear resistance while the component core must retain toughness. As an experienced C15 Round Bars exporter, Jineshwar Steels can support domestic and international enquiries with material documentation and export-oriented packing according to the order requirement.

For procurement teams comparing C15 Round Bars, factors such as grade, material number, diameter tolerance, straightness, surface finish, length, quantity, heat-treatment condition and inspection documentation can influence the final quotation. Therefore, the best price is not necessarily the lowest nominal rate; it should be evaluated together with material conformity, testing, dimensional accuracy, packaging and delivery reliability. Customers who want to buy C15 Round Bars can provide their drawing, material specification or purchase requirement so that the appropriate product condition can be quoted. Jineshwar Steels works with customers seeking both standard stock requirements and project-specific quantities, making it suitable for buyers requiring a C15 Round Bars stockist, dealer or distributor for industrial procurement.

From a manufacturing perspective, C15 Round Bars may be supplied in hot-rolled, cold-drawn, peeled, ground or other agreed conditions depending on size, specification and availability. Cold-drawn and precision-finished conditions can provide tighter dimensional control and improved surface characteristics compared with conventional hot-rolled material, while the selected condition should always correspond to the machining and end-use requirements. Heat treatment can further modify the performance of the finished component. For case-hardening applications, carburizing followed by an appropriate hardening and tempering process is commonly considered. Jineshwar Steels can coordinate supply requirements around dimensional tolerances, surface finish and inspection documentation so customers receive material appropriate for their production process.
