Forging Steel Industry
(DB-6) DIN 1.2714
Steel Properties: Tough die steel with high tempering resistance and good through-hardening properties. This grade isusually supplied in annealed condition or quenched and tempered to a working hardness of 370 to 410 HB(round) or 355 to 400 HB (square, flat).
Applications: Standard steel for forging dies of all types, press dies, extrusion dies, retainer plates, armoured trim dies,hot-shear blades and tool holders.

AISI 4340 (En24)
Steel Properties: AISI 4340 steel properties offer good ductility in the annealed condition, allowing it to be bent or formed. Fusion and resistance welding is also possible with our 4340 alloy steel. ASTM 4340 material is often utilized where other alloy steels do not have the hardenability to give the strength required. For highly stressed parts it is excellent choice. AISI 4340 alloy steel can also be machined by all customary methods.
Applications: EN24 steel is widely used in gears, pinions, shafts, and spindles in the automotive and machine tool industries. Production of parts such as locomotives, cranes, rolling mills, coal cutters, etc. Die casting and hot metal processing, such as mold support, racks and gears, needle angle die casting, Hot stamping of stamping dies, aluminum and steel stamping die beds, low temperature nuts, bolts and rivets. Widely used in plastics, rubber molds, hobs and combination mold buckles, mold stop pins, etc.
