  Heat Treatment of Forgings 13 Issuing time:2025-07-06 15:43 Author:Timothy Forgings Heat Treatment of Forgings Almost all cold-, warm-, and hot-stamped parts must undergo heat treatment to become qualified components. The quality of the heat treatment process plays a decisive role in ensuring and improving part performance, precision, stability, and service life. Raw materials, heating, and heat treatment processes are critical to ensuring part quality. The  forging process  itself also impacts the heat treatment of forgings. The heat treatment of forgings is tailored based on the type of forging and the raw materials used. Key parameters include heating temperature, holding time, and cooling rate. By coordinating heating processes (equipment, heating speed, and atmosphere) and cooling processes (equipment and medium), forgings achieve the required metallographic structure and mechanical properties while avoiding defects (e.g., deformation, cracks, or abnormal structure...

  Forging Quenching Process: Heating Temperature Guidelines 30 Issuing time:2025-06-18 10:57 Author:Timothy Forging Forging Quenching Process: Heating Temperature Guidelines The heating temperature for forging quenching is determined by the steel type,  micro structure , and desired mechanical properties. Below is a detailed breakdown of temperature selection principles for different steel categories, along with practical considerations and advanced techniques: 1. Quenching Temperature Ranges by Steel Type 1.1  Hypothyroid  Steels (e.g., 45# Steel, 40Cr) ·  Heating Temperature :  AC ₃  + (30–50°C) o  Ensures full  pasteurization  while preventing excessive grain growth. o  Avoid temperatures below AC ₃  to eliminate retained ferrite (reduces hardness) or above AC ₃  +50°C to prevent coarse  austerity  grains (degrades toughness). 1.2  Eutectic  Steels (e.g., T8, T10 Tool Steels) ·  Heating Temperat...
