　　Description of SKD61 tool steel

　　SKD61 is a tool steel with high hardness and wear resistance after heat treatment.模具钢And medium carbon steel. It also has good hardenability and thermal fatigue stability.

　　To forge SKD61 tool steel, first slowly preheat it to 750 C (1382 F), keep the temperature for enough time, and then quickly heat it to 1050-1100 C (1922-2030 F). Then start forging to ensure that the forging temperature is higher than 850 C (1562 F). After H13 steel forging is completed, SKD61 tool steel must be cooled slowly.

　　加热至840-860°C(1544-1580°F)，在炉中冷却之前以20°C(68°F)/小时的更大速度彻底浸泡，然后冷却至600°C(1112°F)。然后在空气中冷却。

　　在制造产品之前，工具钢的应力消除是非常必要的。SKD61工具钢在磨削、加工、切割和铣削时，必须在硬化前消除内部应变，以将变形的可能性降至更低。为了消除应力，将SKD61钢零件小心加热至700°C(1292°F ),以获得足够的均热时间。然后在炉中或空气中冷却。

　　首先，SKD61钢应预热至780-820°C(1436-1508°F)并浸泡足够的时间，以确保彻底浸泡。然后快速加热至1000-1030°C(1832-1886°F)并浸泡约30分钟。在空气或油中冷却。

　　将SKD61工具钢零件加热至回火温度，并浸泡足够的时间，直至完全浸泡。通常的回火温度范围是400-650°C(752-1202°F)SKD 61。模具钢硬度取决于工具硬度要求和工作温度。SKD61回火数据如下，供您参考:

　　SKD61工具钢用于不同类型的铝、镁和锌压铸模具、铝和黄铜挤压模具、垫圈、心轴、压力垫、从动件、垫板、模具外壳、模具支架和铜和黄铜挤压用接合环。SKD61用于热冲压模具、分体热镦模具、颚式模具、热冲压、冲孔和切边工具。SKD61工具钢的应用还包括塑料模具、热作剪切刀片和热锻模具。
