Case-Hardening Steels

Case-hardening steels are special alloy steels with low carbon content that gain high wear resistance and impact strength through a surface-hardening process (carburising). In these steels the surface layer becomes very hard while the core remains tough and resilient. This provides both high load-bearing capacity and long service life, enabling the parts to carry heavy loads and withstand impact-type loading. In addition to gears, case-hardening steels should be used where high wear and fatigue resistance is required — machined shafts, pistons, chain links, discs, guides and bearing housings.

Key Properties

• High surface hardness
• Excellent wear resistance
• High resistance to impact and fatigue
• Tough, durable core
• Long service life
• Superior mechanical properties after surface hardening such as carburising, nitriding and carbonitriding

Applications

Case-hardening steels are especially preferred for machine parts used in machine parts subject to high wear and heavy loads:

• Automotive gears
• Gearbox (transmission) parts
• Differential gears
• Sprockets
• Shafts and axles
• Camshafts
• Bearing parts
• Industrial machinery equipment

Advantages

Through case hardening, the outer surfaces of parts can reach 58–62 HRC while the core remains flexible and tough. This reduces the risk of fracture — particularly in gears and power-transmission elements — while significantly extending service life.

Case-hardening steels are among the indispensable materials for engineering applications demanding high performance, long life and reliability.

Cold Drawn Bars

Cold drawn bars are high-precision steel products obtained by shaping hot rolled steel bars at room temperature through special drawing processes. This method improves surface quality, tightens dimensional tolerances and enhances mechanical properties.

During cold drawing, the strength and hardness of the material increase while high precision is achieved in diameter and cross-section. Thanks to these properties, cold drawn bars are preferred in automotive, machine building, hydraulic and pneumatic systems, fasteners, the die and mould industry, defence and precision engineering applications.

Produced in round, square, hexagonal and special sections, cold drawn bars improve efficiency in machining thanks to their superior surface quality and high dimensional accuracy. They offer important advantages such as low surface roughness, shorter machining times and lower tool wear.

Mechanical tests, dimensional checks and surface quality inspections are carried out during production to ensure compliance with national and international standards. For applications requiring high strength, excellent surface quality and tight tolerances, cold drawn bars offer a reliable and economical solution.

Forged Bars

Forged bars are high-strength engineering materials produced by shaping steel billets or ingots at high temperatures using forging presses and hammers. During forging, the internal structure of the steel is densified, the grain structure refined, internal voids reduced and the mechanical properties significantly improved.

As a result, forged bars can be used with confidence in applications requiring high strength, superior impact resistance and fatigue resistance. They are especially preferred in critical sectors such as heavy industry, energy, automotive, defence, shipbuilding, mining and machine building.

Forged bars are widely used to produce shafts, spindles, gears, axles, turbine components, pressure-equipment parts and machine components working under high loads. Because the grain flow of the material is aligned with the part geometry during production, machined parts achieve higher reliability and longer service life.

Available in round, square, rectangular and special sections, forged bars meet diverse engineering needs with a wide choice of sizes and grades. Quality processes supported by chemical analyses, ultrasonic testing, mechanical tests and dimensional checks ensure compliance with national and international standards.

Offering high mechanical performance, a homogeneous internal structure and superior durability, forged bars are an ideal engineering solution for critical applications requiring reliability and long life.
