H13 Round Bar

H13 steel rods are a type of tool steel that are used in hot working applications. They are known for their high hardness, toughness, and resistance to heat. H13 steel rods are available in various forms, including round bars. Properties: Hardness: H13 steel rods are known for their high hardness and abrasion resistance Toughness: H13 steel rods are known for their high toughness Heat resistance: H13 steel rods are known for their excellent heat resistance Wear resistance: H13 steel rods are known for their high wear resistance to thermal shock Machinability: H13 steel rods are known for their good machinability Ductility: H13 steel rods are known for their good ductility Polishability: H13 steel rods are known for their good polishability Uses: H13 steel rods are used to make die casting tools, cold heading tools, and other high-temperature applications H13 steel rods are used to make components like ejector pins, apparatus holders, and molds for die casting Composition: H13 steel rods contain chromium, molybdenum, and vanadium H13 steel rods also contain smaller amounts of other alloying elements such as silicon and manganese The chemical composition of H13 tool steel is: Carbon: 0.32–0.45% Silicon: 0.80–1.20% Manganese: 0.20–0.50% Phosphorus: 0.03% Sulfur: 0.03% Chromium: 4.75–5.50% Molybdenum: 1.10–1.75% Nickel: 0.3% Vanadium: 0.80–1.20% Copper: 0.25% Iron: Balance H13 tool steel is a hot work tool steel that's used to make dies for forging, extrusion, and die-casting. It's known for its high hardness, toughness, and heat resistance. Heat treatment Preheat H13 tool steel to 1500°F (816°C) Increase the temperature to 1850°F (1010°C) and hold for 15–40 minutes Air-quench the steel Tempering Temper H13 steel immediately after quenching Temper at a temperature between 1000–1150°F (538–621°C) Hold the steel at the tempering temperature for 1 hour per inch of thickness Let it cool normally for 2 hours
