Ventura Alloy and Steels Stocks and Supplies Die Block Steel DB6 / DIN 2714 in India and abroad. DB6 tool steel is an extreme pass on steel with high treating resistance and great through-solidifying properties. Its nickel substance has it uncommonly effect safe – a highly recommendable element for vast mallet & press bites the dust alike. 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).

Utilized as standard die block steel for manufacturing passes on of different kinds, press bites the dust, expulsion kicks the bucket, retainer plates, heavily clad trim bites the dust, hot shear sharpened pieces of steels and instrument holder.

STEEL PROPERTIES

The exceptional hot work pre-solidified tool steel has great toughness and high wear resistance. DB6 die steel is generally provided in hard, quenched, tempered and annealed condition in strengthened condition in exceptional cases. Normally it’s working hardness is 360-430 BHN. This steel grade is the updated type of DIN 2713 for higher efficiency and performance.


APPLICATIONS

Dies for Specially Drop and Close Die Forgings for Hammers & Mechanical Presses, Die Moulds, Shoe Blocks, Die Holder, Piston Rods, Bolster, Cranks, Cassettes, Plastic Moulds, Shearing Blades, Tools etc.
