1.2713 is a widely used hot work tool steel that belongs to the German standard DIN 17350. It is known for its high toughness, good wear resistance, and excellent resistance to thermal fatigue, making it suitable for heavy-duty applications such as forging dies, extrusion tools, and die-casting molds. Many countries have equivalent steel grades to DIN 1.2713, such as: L6 from American standard ASTM A681, 55NiCrMoV6 from International standard ISO 4957, SKT4 from Japanese standard JIS G4404, 5CrNiMo from Chinese standard GB/T 1299.

8：Application
1.2713 is a high toughness, impact resistant hot work die steel, which is widely used in the following fields:
1. Hot Work Dies
1) Forging Dies: Heavy-duty forging dies (e.g., hammer forging dies, press forging dies); molding of gears, crankshafts, connecting rods, and other large forgings.
(2) extrusion die: aluminum, copper alloy hot extrusion die (such as profiles, pipe extrusion).
(3) die-casting mold: zinc, aluminum, magnesium alloy die-casting mold.
2. Cold work molds
1) Punching die: thick plate punching, drop die.
(2) shear blade: heavy duty shear blade (such as billet shear).
(3) Cold heading die: bolt, nut molding die.
3. Plastic mold
1) injection mold: for high wear-resistant, highly polished requirements of the mold (such as engineering plastic parts).
(2) Blow mold: bottle embryo, container molding mold.
