C45 Round Bars are medium-carbon steel bars widely used where a combination of strength, hardness, machinability and wear resistance is required. Jineshwar Steels supplies C45 round bars for engineering, automotive, machinery, fabrication and general industrial applications in different diameters, lengths and supply conditions. C45 is commonly associated with EN 10083-2 / C45E-type medium-carbon steel grades, while the exact applicable specification and delivery condition can vary according to the customer's requirement. As an experienced C45 round bars manufacturer, exporter, supplier, stockist, dealer and distributor, Jineshwar Steels focuses on supplying dimensionally consistent material supported by appropriate inspection and documentation.

The popularity of C45 steel comes from its useful balance between mechanical performance and machinability. Compared with low-carbon steels, C45 contains a higher carbon level, allowing it to achieve greater hardness and strength after suitable heat treatment. This makes C45 round bars suitable for components such as shafts, axles, pins, bolts, studs, gears, rollers, machine parts and other engineering components. Depending on the application, the material may be supplied in hot-rolled, cold-drawn, peeled, ground, normalized or other agreed conditions. Customers looking to buy C45 round bars can specify diameter, length, surface condition, heat-treatment condition, quantity and applicable standard so that the material can be supplied according to the intended application.

C45 Round Bars Latest Price List

As a leading manufacturer and trusted supplier, Jineshwar Steels understands that the right steel grade is only one part of a successful procurement decision. Diameter tolerance, straightness, surface condition, chemical composition, mechanical properties, heat treatment and inspection documentation can all influence the suitability of a round bar for a finished component. For this reason, requirements are reviewed before supply, particularly for applications involving machining, induction hardening, quenching and tempering or other secondary processing. Material can be arranged with relevant inspection documentation such as a Mill Test Certificate or EN 10204 documentation where specified in the purchase order and available for the supplied material.

C45 Round Bars are particularly useful in applications where components need reliable mechanical performance without moving into more highly alloyed steel grades. The material can be machined into shafts, pins, bushes, studs, rods and other precision-engineered components. Its response to heat treatment makes it useful when a component requires a harder surface or improved strength compared with an untreated mild-steel component. However, the appropriate heat-treatment route should always be selected according to component size, geometry, required hardness, operating conditions and applicable technical standards. Jineshwar Steels can supply C45 round bars in sizes and conditions suitable for machining and fabrication requirements, subject to availability and agreed specifications.

For procurement teams, choosing a dependable C45 round bar supplier also means obtaining consistent documentation and clear commercial communication. Jineshwar Steels supports enquiries involving standard sizes as well as project-specific requirements. Customers can request material according to diameter, cut length, quantity, surface finish and inspection requirements. Whether the requirement is for a small engineering order, regular manufacturing consumption or an export shipment, the company can coordinate material sourcing and supply based on the agreed technical specification. The best price for C45 round bars depends on diameter, quantity, manufacturing condition, heat treatment, market conditions, testing requirements, packing and delivery destination, so quotations are prepared according to the actual requirement rather than using a generic price.
