Troubleshooting Common Heat Treatment Defects: Distortion, Brittleness & Cracking, Insufficient Hardness? Most Effective Solutions Here 2025-12-10 Troubleshooting Common Heat Treatment Defects: Distortion, Brittleness & Cracking, Insufficient Hardness? Most Effective Solutions Here During the heat treatment process, workpieces often suffer from defects such as distortion, brittleness and cracking, insufficient hardness, oxidation and decarburization. These issues not only increase the scrap rate but may also affect subsequent assembly and operational safety. In fact, most defects stem from improper process parameters, inadequate equipment precision, or operational errors. This article compiles the causes and solutions for 5 common defects to help you enhance production stability. I. Defect 1: Excessive Workpiece Distortion (e.g., shaft bending, sheet warping) • Causes: Excessively fast heating rate, uneven cooling, improper loading method (overstacking of workpieces), incorrect selection of quenching medium.   • Solutions:   a. Adopt "stepwise heating" (low-temperature preheating → high-temperature holding) to reduce thermal stress;   b. Optimize cooling methods: Use marquenching for thick and large workpieces, and isothermal quenching for thin-walled workpieces;   c. Improve furnace loading: Secure workpieces with special fixtures to avoid stacking and ensure uniform air flow inside the furnace;   d. Select appropriate quenching medium: Adjust cooling rate when switching from oil quenching to water quenching, or use water-soluble quenching agents. II. Defect 2: Workpiece Brittleness and Cracking (Easy fracture after quenching, insufficient toughness) • Causes: Excessively high quenching temperature, excessively fast cooling rate, delayed tempering, excessive impurities in materials.   • Solutions:   e. Reduce quenching temperature (adjust according to material composition, e.g., lower the quenching temperature of high-carbon steel from 860℃ to 820℃);   f. Slow down the cooling rate: Oil quenching is milder than water quenching, or add cooling modifiers to the quenching medium;   g. Perform tempering within 2 hours after quenching to eliminate internal stress;   h. Use high-purity raw materials to avoid excessive sulfur, phosphorus and other impurities. III. Defect 3: Insufficient Hardness (Failure to meet preset hardness standards) • Causes: Insufficient heating temperature, inadequate holding time, slow quenching cooling rate, low carbon content in materials.   • Solutions:   i. Increase heating temperature (within the allowable range of the material, e.g., raise the temperature of medium-carbon steel from 830℃ to 850℃);   j. Extend holding time (adjust according to workpiece thickness: extend holding time by 30 minutes for every additional 10mm thickness);   k. Replace with a medium with faster cooling rate (e.g., switch from water quenching to brine quenching, or check if the quenching medium is aged);   l. Test the carbon content of raw materials in advance to ensure compliance with process requirements. IV. Defect 4: Oxidation and Decarburization (Workpiece surface blackening, reduced hardness) • Causes: Improper control of furnace atmosphere (excessive oxygen), excessively long heating time, poor equipment airtightness.   • Solutions:   m. Use atmosphere-controlled furnaces (e.g., nitrogen or methanol cracked gas protection) to isolate oxygen;   n. Shorten heating time to avoid excessive oxidation;   o. Inspect furnace door gaskets and repair air leakage points;   p. For decarburized workpieces, repair them through carburizing/nitriding replenishment processes. V. Defect 5: Uneven Case Depth (Inconsistent thickness of surface hardened layer) • Causes: Uneven flow of furnace atmosphere, improper workpiece loading position, unstable carburizer/nitriding agent concentration.   • Solutions:   q. Optimize the internal air flow design of the furnace and install deflectors;   r. Distribute workpieces evenly to avoid blocking the contact between the carburizer/nitriding agent and the workpiece surface;   s. Monitor the concentration of the carburizer/nitriding agent in real time and maintain stability through an automatic feeding system.
Industrial Heat Treatment Furnace Selection Guide: 4 Core Dimensions to Avoid Mistakes from Capacity to Process 2025-12-09 Industrial Heat Treatment Furnace Selection Guide: 4 Core Dimensions to Avoid Mistakes from Capacity to Process Heat treatment furnaces are the core equipment determining process results — for the same workpiece, choosing the right furnace ensures performance consistency and reduces energy consumption; choosing the wrong one may lead to soaring scrap rates and doubled production costs. For manufacturing enterprises, selecting a suitable heat treatment furnace requires considering multiple factors such as capacity, process, and material properties. This article compiles a practical selection guide to help you avoid common pitfalls. I. Select by Heat Treatment Process: Match Core Functions Annealing/Normalizing: Prioritize box-type resistance furnaces or pit-type furnaces. These devices offer uniform heating and flexible adjustment of holding time, suitable for batch processing to improve material machinability, compatible with low-carbon steel, cast iron, and other materials. Quenching/Tempering: Recommend mesh belt continuous furnaces or pusher-type furnaces. Featuring high automation, they enable continuous "heating-quenching-tempering" operations with a temperature control accuracy of ±1℃, ideal for mass production of auto parts and standard components. Nitriding/Carburizing: Must select specialized gas nitriding furnaces or vacuum carburizing furnaces. These furnaces provide strong atmosphere tightness, precise control of nitrogen/carbon concentration, and oxidation prevention, suitable for surface hardening of precision components. Precision Small Parts Processing: Optional vacuum furnaces or ion nitriding furnaces. The vacuum environment prevents workpiece oxidation and decarburization, while the low-temperature processing of ion nitriding furnaces ensures dimensional accuracy, making them suitable for electronic components and aerospace parts. II. Select by Production Capacity: Balance Efficiency and Cost Small-Batch Production (Daily Output 2000 Pieces): Opt for mesh belt continuous furnaces or stepping furnaces. Offering automated assembly line operations, they achieve a capacity of 1-5 tons/day with low energy consumption and high consistency, suitable for standardized production in large manufacturing enterprises. III. Select by Material Characteristics: Avoid Process Failure Low-Carbon Steel/Medium-Carbon Steel: Conventional resistance furnaces or gas-fired furnaces are optional, featuring low cost and meeting basic heat treatment requirements. Alloy Steel/Stainless Steel: Prioritize vacuum furnaces or atmosphere-protected furnaces to avoid oxidation and decarburization, ensuring material corrosion resistance. Precision Castings/Thin-Walled Parts: Choose low-temperature uniform heating furnaces (e.g., infrared heating furnaces) to reduce deformation and cracking caused by thermal stress. IV. 2 Key Indicators Not to Be Ignored Temperature Control Accuracy: For core processes (e.g., nitriding, quenching), select equipment with an accuracy of ±1℃; for general processes, it can be relaxed to ±3℃. Energy Consumption Index: Prioritize Class 1 energy-saving furnaces (energy consumption ≤ 500kWh/ton) equipped with waste heat recovery systems, which can save over 30% on electricity costs in long-term use.
