Case-hardening steels: Characteristics, Advantages and Gieffeacciai’s Offer
Case-hardening steels are an ideal solution for mechanical components subject to high surface stresses and which must have good toughness to the core. These steels are used in particular for the manufacture of gears, shafts, pinions, racks and other elements requiring surface resistance to wear, seizure and surface damage phenomena, maintaining toughness and excellent mechanical characteristics.
What are case-hardening steels?
Case-hardening steels are low carbon steels (0.10-0.25%), designed to undergo a thermochemical treatment called carburizing, which consists of a surface enrichment of carbon in the order of 0.5-1.0 mm. The subsequent heat treatment of hardening and tempering allows to obtain in surface a martensitic structure, extremely hard (58-64 HRC), and at heart a toughness structure able to resist the stresses to which the component is subjected.
The advantages of case-hardening steels
- High surface hardness
- Resistance to wear, seizure and surface damages
- High fatigue strength
- Good machinability before carburizing
