DIN 1.2510 SKS3 O1 Oil Hardening Steel Bars Tool Steel

SKS3 cold hardened high chromium tool steel is a common tool steel with excellent wear resistance and hardness. The following will introduce the characteristics, uses, processing technology and precautions of SKS3 cold-hardened high-chromium tool steel in detail.

First, features:

1. High hardness: SKS3 tool steel has a high hardness, up to 60-62HRC, which can provide excellent cutting ability and wear resistance.

2. Excellent wear resistance: The tool steel contains a high chromium content, which increases its wear resistance and corrosion resistance, and is suitable for making wear-resistant parts.

3. Good cold hardenability: SKS3 tool steel has good cold hardenability, which can be quenched at a lower temperature to maintain a high hardness.

4. Good plasticity: Due to its moderate carbon content, SKS3 tool steel has good plasticity and machinability, which can meet the manufacturing requirements of various tools.

Second, use:

1. Making die and stamping die: SKS3 tool steel's high hardness and excellent wear resistance make it very suitable for making die and stamping die. In the stamping process, the die needs to have a high hardness and wear resistance to ensure its service life and work efficiency.

2. Making cutting tools: The high hardness and cold hardening of SKS3 tool steel make it very suitable for making cutting tools, such as pliers, scissors, etc. These tools need to have high hardness and sharp cutting edges during use to ensure cutting effect and accuracy.

3. Making cold stamping die: Because SKS3 tool steel has good cold hardening, it is suitable for making cold stamping die, such as cooling mouth, cold bending and cold stamping.

Third, processing technology:

1. Heat treatment: SKS3 tool steel generally needs to be heat treated before use, including annealing, normalizing, quenching and tempering processes to improve its hardness and wear resistance.

2. Cutting processing: The cutting of SKS3 tool steel generally uses carbide or high-speed steel tools, requiring sharp tools, cutting speed should not be too fast to avoid overheating resulting in increased tool wear.

3 Grinding processing: Due to the high hardness of SKS3 tool steel, the use of grinding processing, should choose a harder abrasive and control the grinding parameters, in order to avoid too strong abrasive lead to the workpiece surface roughness increase and deformation.

4. EDM processing: SKS3 tool steel is suitable for cutting, hollowed-out, complex shape processing, etc. by electric discharge machining (EDM), which can meet the manufacturing needs of some special shape tools.

Iv. Precautions:

1. Quenching temperature: Due to the good cold hardening of SKS3 tool steel, the quenching temperature is generally low, about 850-880 ° C.

2. Tempering treatment: After quenching, the SKS3 tool steel needs to be tempered to relieve internal stress and improve toughness and fracture resistance. The tempering temperature is generally controlled between 150-250 ° C.

3. Cutting lubrication: In the cutting process, it should be ensured that the tool and the workpiece are fully lubricated to reduce the cutting temperature and avoid wear and poor surface quality.

4. Prevent surface oxidation: SKS3 tool steel is prone to surface oxidation in high temperature and high oxygen content environment, so attention should be paid to protection during processing to avoid the surface quality of the workpiece being affected.

The above is about SKS3 cold-hardened high chromium tool steel introduction, I hope to help you.
