STEEL PROPERTIES
The special Hot Work Pre-hardened Steel has great toughness and high wear resistance. DB6 Steel is generally supplied in hard, quenched, tempered and also in annealed condition in special cases.Usually it's working hardness is 360-430 BHN. This steel grade is the upgraded version of DIN 2713 for greater efficiency and performance.
APPLICATION
Dies for Specially Drop and Close Die Forgings for Hammers & Mechanical Presses, Die Moulds,Shoe Blocks, Die Holder, Cassettes, Piston Rods, Cranks, Boaster, Shearing Blades, Tools, plastic moulds Etc.
