Product Description

Product Description

D2 (1.2379/SKD11) Cold Work Tool Steel Block Precision Machined

D2 (1.2379 / SKD11) is a high-carbon, high-chromium air-hardening tool steel, heat-treatable to 60-62 HRC. It offers excellent wear and abrasion resistance due to a high volume of carbides in its microstructure.

D2 is widely used for long-run cold work applications that require very high wear resistance and high compression strength. It is machinable in the annealed condition and, like other air-hardening tool steels, exhibits minimal distortion during heat treatment. Available forms include de-carb-free rounds, flats, squares, ground flat stock, and drill rods.

D2 Steel Quenching & Tempering
 

Stage

Key Parameters

Performance Impact

Quenching

1020~1040ºC × 30min/25mm

Increases hardness and wear resistance

Cooling

Oil cooling/gas quenching (≥6 bar)

Forms martensite; insufficient cooling reduces hardness

Deep Cooling

-80~-196ºC × 2 hours (optional)

Increases hardness and dimensional stability

Tempering

180~530ºC × 2 hours × 2 times

Relieves stress, adjusts hardness/toughness
