What is D2 Tool Steel?

D2 Tool Steel is a high-carbon, high-chromium cold-work tool steel designed for applications that require high wear resistance and hardness. With around 12% chromium content, it offers some degree of corrosion resistance, making it semi-stainless compared to conventional tool steels.

Also known as: DIN 1.2379, X153CrMoV12, JIS SKD11

Category: Cold Work Tool Steel

Hardness (after heat treatment): 58–62 HRC

D2 is a versatile tool steel—you’ll find it in blanking dies, punches, cutting blades, and forming tools where dimensional stability and toughness are critical.

Key Characteristics of D2 Tool Steel

• Exceptional wear and abrasion resistance
   
• High hardness (up to 62 HRC after treatment)
   
• Excellent dimensional stability during heat treatment
   
• Good compressive strength

Semi-stainless properties (better corrosion resistance than most tool steels)

Key Features & Benefits

• Exceptional wear resistance – performs well in abrasive environments.
• High hardness – up to 62 HRC after proper heat treatment.
• Good corrosion resistance due to high chromium content.
• Dimensional stability – minimal distortion during heat treatment.
• Cost-effective long tool life – reduces replacement and downtime.
• Versatility – suitable for blanking, shearing, and forming applications.
   

D2 Tool Steel vs Other Tool Steels

• D2 vs O1 Tool Steel: D2 offers better wear resistance and semi-stainless properties, while O1 is easier to machine and heat treat.
   
• D2 vs A2 Tool Steel: D2 has higher wear resistance but A2 provides better toughness.
   
• D2 vs 420 Stainless Steel: D2 is harder and more wear-resistant, while 420 stainless offers superior corrosion resistance.
