C20 Round Bars are low-carbon engineering steel bars valued for their combination of machinability, ductility, weldability and dependable performance in general mechanical applications. C20 is commonly identified as 1.0402 and is associated with low-carbon, unalloyed steel used for engineering components and case-hardening applications. Depending on the applicable standard and supply condition, C20 material can be provided as hot rolled, bright drawn, peeled, turned, ground or otherwise machined round bar. Jineshwar Steels supplies C20 Round Bars for customers requiring controlled material quality, dimensional consistency and application-specific supply. As an experienced manufacturer, supplier, stockist and exporter, the company can support standard and customized requirements with appropriate documentation and inspection arrangements.

The relatively low carbon level of C20 gives the steel useful forming and machining characteristics while maintaining adequate strength for many general engineering components. Typical published composition ranges include approximately 0.17–0.23% carbon, 0.30–0.60% manganese and up to 0.40% silicon, with phosphorus and sulfur controlled within specified limits depending on the standard. This composition makes C20 Round Bars suitable where a combination of machinability, toughness and economical fabrication is more important than the higher strength associated with medium- or high-carbon grades. For customers looking to buy C20 Round Bars, Jineshwar Steels can offer material according to required diameter, length, surface finish and delivery condition, subject to technical confirmation.

C20 Round Bars Latest Price List

As a C20 Round Bar manufacturer, Jineshwar Steels focuses on supplying material that matches the customer's stated dimensional and technical requirements rather than relying only on a generic grade description. Round bars may be supplied in different surface conditions according to the order, including hot rolled or bright-finished forms, while cut-to-length requirements can also be discussed. Bright steel standards such as EN 10277 cover drawn, peeled/turned and ground bright bars intended for mechanical purposes, with requirements covering aspects such as mechanical characteristics, surface condition, dimensions and inspection documentation. This technical approach helps the customer select the right product condition for machining, fabrication, shafts, pins, bushings and other engineering components.

C20 Round Bars are particularly useful when a component needs reliable machinability and a relatively tough low-carbon steel base. Typical applications include shafts, pins, bushes, spacers, hubs, brackets, fixtures, fasteners and general machine components. Low-carbon C20 can also be considered for case-hardening applications where the component requires a harder surface while retaining a tougher core, provided the selected specification and heat-treatment procedure are appropriate. For engineering buyers, this versatility makes C20 an economical material option for components that do not require the higher alloy content or strength of more specialized engineering steels.

Jineshwar Steels serves customers requiring C20 Round Bars for machinery manufacturing, automotive components, fabrication, general engineering, maintenance and industrial production. As a trusted supplier, dealer and distributor, the company can coordinate material requirements based on diameter, length, quantity, finish, inspection and certification needs. Buyers can request material supplied with appropriate documentation such as a Mill Test Certificate or inspection certificate where specified. Chemical analysis and mechanical testing can be arranged according to the applicable purchase specification, while additional inspections may be considered for critical applications.
