A case-hardening process for development of martensitic case-depth of up to 3.0 mm by increasing surface carbon content in austenitic region, with subsequent hardening and tempering.

Basic Treatments

Carburising And Carbonitriding

Carburising A case-hardening process - case-depth up to 3,0 mm

Application

For components produced using case-hardening steel (low-alloy steel) where good wear resistance, surface resistant to compression, or impact loading is required.

Transmission parts for automotive, rail and energy industry, or other mechanical components.

Benefits

Improves wear resistence, fatigue strength, and general toughness of parts.

Elevated mechanical properties of low-grade steel; high surface hardness while maintaining core toughness

Technical specification

Martensitic case-depth of up to 3,0 mm is developed by increasing surface carbon content in austenitic region with high carbon solubility. Subsequent hardening and tempering is performed to reach desired properties.

For part dimension up to 900 x 900 x 1200 mm and weight of up to 1500 kg.

Carbonitriding A modified case-hardening process - case-depth of up to 1,0 mm

Application

Recommended for highly stressed parts, mass produced automotive parts, gears, or other finished parts made of low alloy and plain carbon steels where, extra hard, uniform case is needed.

Benefits

Improves wear resistance, fatigue strength, and general toughness of parts. Higher surface hardness compared to carburizing.

Elevated mechanical properties to low-grade steel; high surface hardness while maintaining core toughness.

Case with improved hardenability and temper resistance due to nitrogen addition.

Technical specification

Treatment is usually carried out in a temperature range from 850 to 890°C in carbon and nitrogen rich atmosphere to develop martensitic case-depth of up to 1,0 mm. Subsequent hardening and tempering are performed to reach desired properties.

For part dimension up to 900 x 900 x 1200 mm and weight of up to 1500 kg.
