Hot Work Tool Steel

Hot Work Tool Steel

The characteristic hardness and resistance of hot work tool steel is due to high level of carbide, moderate level of alloy and low level of carbon.Hot work tool steel have a working temperature range of 250-700 ℃. They are used as steel for hot cutting knives, steel for press extrusion molds, forging presses, steel for molds for pressurized molds, molds for the production and processing of metals in solid and liquid form.Tool steel products are resistant to corrosion, have good toughness, fire crack resistance, heat resistance, very high strength, hardness, and abrasion resistance at high temperatures.H1 – H19 steels contain approx. 5% chromium, H20 – H39 contain approx. 10-18% tungsten and 3-4% chromium, and our H40 – H59 steels are based on molybdenum.
