Case Hardening Steel

Easily machined case hardening alloy steel which is susceptible to achieving a tough surface layer, combined with a highly resistant core. Responds well to welding and oxyacetylene welding due to its low carbon content; however, in certain instances and for extra thick steels, lightly pre-heating the steel is recommended.

17CrNiMo6/18CrNiMo7-6

High hardenability. For case hardened steel parts with a core resistance of up to 150 Kg/mm2.

1. Use:For the manufacturing of large case hardened steel parts with very high resistance and surface hardness. High-responsibility engine and machine parts.

2. Delivery status (See technical data sheet).

3. Average chemical composition in % (See technical data sheet).

F-1522

Good machinability, but susceptible to deformation due to low hardenability.

1. Use:For the manufacturing of small case hardened steel parts requiring little responsibility and in which high tenacity in the nucleus is not necessary.

2. Delivery status (See technical data sheet).

3. Average chemical composition in % (See technical data sheet).

F-1540

For case hardened steel parts with core resistance of 85-125 Kg/mm2.

1. Use:For the manufacturing of parts with a high surface hardness, average resistance and high tenacity core. Motoring parts, gears, cams, etc.

2. Delivery status (See technical data sheet).

3. Average chemical composition in % (See technical data sheet).

F-1550

For case hardened steel parts with a core resistance of 75-130 Kg/mm2.

1. Use:For parts with very hard surfaces and average resistance. Gears, cams, crowns and general parts that will need to withstand high amounts of friction.

2. Delivery status (See technical data sheet).

3. Average chemical composition in % (See technical data sheet).

F-158 Mo

For case hardened steel parts with a core resistance of 90-140 Kg/mm2. Weldable if preheated.

1. Use:For medium- thickness parts subjected to shear stress and impact and which require a hard surface and a high-tenacity core. For gears of all kinds.

2. Delivery status (See technical data sheet).

3. Average chemical composition in % (See technical data sheet).
