Die Steel grades D2 and D3 exhibit high hardness levels ranging from 55 to 62 HRC, making them suitable for demanding tooling applications. Both grades possess impressive tensile and yield strengths of 1,400 to 1,600 MPa and 1,100 to 1,300 MPa, respectively. With low elongation of 5 to 10% and impact toughness values between 15 and 30 J, they demonstrate durability under stress while being resistant to wear. These properties make D2 and D3 ideal for high-performance dies and tooling in cold work applications.
