Case hardening steels

This is a case-hardening alloy steel, easy to machine, and offers the potential to achieve a very hard surface layer, combined with good core strength. It presents no problems when welding or flame-cutting due to its low carbon content. However, in some cases, and for thick combined thicknesses, slight preheating is recommended.

17CrNiMo6/18CrNiMo7-6

High hardenability. For cemented parts with core strengths of up to 150 kg/mm2.

1. Use: For the manufacture of large, cemented parts with high strength and surface hardness. These are used for heavy-duty engine and machine parts.

2. Supply status (see technical sheet).

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

F-1522

Good machinability, but prone to deformation due to its low hardenability.

1. Use: For the manufacture of small cemented parts that require little responsibility and where high core toughness is not required.

2. Supply status (see technical sheet).

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

F-1540

For cemented parts with a core strength of 85-125 Kg/mm2.

1. Use: For the manufacture of parts with high surface hardness, medium strength, and high core toughness. Automotive parts, gears, cams, etc.

2. Supply status (see technical sheet).

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

F-1550

For cemented parts with a core strength of 75-130 Kg/mm2.

1. Use: For workpieces with high surface hardness and medium strength. Gears, cams, crowns, and general workpieces that must withstand high friction.

2. Supply status (see technical sheet).

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

F-158 Mo

For cemented parts with core strengths of up to 90-140 kg/mm2. It can be preheated and welded.

1. Use: For medium-thickness workpieces subjected to shear and impact stresses requiring surface hardness and core toughness. For gears of any type.

2. Supply status (see technical sheet).

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