DB6 Steel is an extreme pass on steel with high treating resistance and great through-solidifying properties. This evaluation is generally supplied in toughened condition or extinguished and tempered to 1300 N/mm² & a working hardness of 370 to 410 HB (round) or 355 to 400 HB (square, level).


Its nickel substance has it uncommonly effect safe – a highly recommendable element for vast mallet & press bites the dust alike.
