C45 round bar, ground, untreated

General mechanical engineering

The C45 ground round bar in the untreated condition represents an economical and reliable choice for the mechanical engineering industry, where its medium strength characteristics and good machinability make it ideal for standard mechanical components. The ground finish ensures precise dimensional tolerances, eliminating the need for further finishing operations.

Machine tool manufacturers use this steel for the production of transmission shafts, pins, bushings and structural components that do not require high mechanical performance but need dimensional precision and operational stability.

Metal fabrication and structural work

In the metal fabrication sector, ground untreated C45 is widely used for the production of connecting elements and structural components. Metal structure manufacturers appreciate its versatility for the production of pins, fasteners, supports and joining elements that require dimensional precision.

Its ability to withstand moderate static loads and ease of machining make it particularly suitable for light fabrication work and applications where the cost-performance ratio is a decisive factor in material selection.

Entry-level automotive sector

In the automotive sector, ground untreated C45 round bar is used for non-critical components that nevertheless require dimensional precision. Automotive component manufacturers use it for the production of supports, spacers, bushings and fastening elements that operate under moderate stress conditions.

The ground finish enables precise fits and optimal surface roughness for components requiring automated assembly and tight tolerances, while keeping production costs contained.

Mould and equipment industry

Mould and tool manufacturers use ground untreated C45 for the production of equipment and supports that do not require high surface hardness. This steel is particularly suitable for guides, mould supports, drilling jigs and production equipment requiring dimensional stability.

Its good weldability and ease of machining make it ideal for the production of customized equipment and machine components that need to be frequently modified or adapted during production processes.

Hydraulic and pneumatic sector

In the hydraulic sector, ground untreated C45 round bar is used for the production of components for low-pressure systems. Hydraulic component manufacturers use it for pneumatic cylinders, piston rods, supports and sealing elements that operate under moderate pressure conditions.

The dimensional precision achieved through grinding is essential to ensure correct fits with gaskets and seals, while the steel's natural mechanical characteristics are sufficient for most standard hydraulic applications.

Mechanical subcontractors and prototyping

Mechanical subcontractors choose ground untreated C45 for the production of prototypes and small batches where machining speed and cost containment are top priorities. Its excellent machinability makes it ideal for turning, milling and drilling operations.

This steel represents an optimal solution for the production of customized components, spare parts and mechanical elements that require dimensional precision but do not need specific heat treatments, optimising production times and costs.
