Advanced Metallurgy for CPP TPM IDAH
Beyond dimensional flexibility, JARAY offers metallurgical customization for CPP, TPM, and IDAH pellet mills. While X46Cr13 stainless steel remains the primary grade, alternative materials such as 18NiCrMo5 and 20CrMnTi are available for specialized wear and strength requirements.
Material Consultation for Global Pellet Manufacturers
Our technical specialists provide guidance on selecting optimal steel grades based on pellet material, operating pressure, and wear conditions. This consultative approach ensures each forged blank delivers balanced hardness, toughness, and machinability for diverse pellet mill brands.
Flexible Production Volumes for OEM Contracts
JARAY accommodates small research batches, pilot production runs, and large-volume OEM supply agreements. Flexible manufacturing planning allows pellet mill manufacturers to secure consistent forged blank supply while maintaining quality, lead time reliability, and cost efficiency.
Metallographic Testing of MUZL 600 Ring Die in X46Cr13 Stainless Steel After Heat Treatment
The metallographic examination was conducted on a sample ring die (MUZL 600) manufactured from X46Cr13 stainless steel in the quenched and low-temperature tempered condition. Testing was performed using a Time TMR2000 inverted metallographic microscope and a TMV-1S microhardness tester with a 1.0 kgf load to evaluate structural integrity and hardness compliance after final heat treatment.
Heat Treatment Analysis
Metallographic testing was performed on a MUZL 600 ring die made from X46Cr13 stainless steel in quenched and low-temperature tempered condition. Evaluation using an inverted metallographic microscope and 1.0 kgf microhardness testing confirmed structural integrity and post-treatment hardness compliance.
Non-Metallic Inclusion Analysis
Non-metallic inclusion assessment was carried out in accordance with GB/T 10561-2005 under 100× magnification in the uneroded state. The evaluation showed Class A, B, and C inclusions at zero level, with Class D fine inclusions at 0.5 level and no DS inclusions detected. The observed inclusion length was 0.71 mm within an inspection area of 0.5 mm², confirming that the material meets the technical requirements
Material Microstructure Evaluation
Microstructural analysis was performed after etching with 2%–4% picric acid alcohol solution. The matrix structure predominantly consists of lath martensite with uniformly distributed undissolved carbide particles. This structure indicates proper heat treatment transformation and ensures the mechanical strength and wear resistance required for pellet mill ring die applications.
Microhardness Test Results
Microhardness testing under a 1.0 kgf load in the uneroded condition confirmed that the hardness values comply with the specified requirements of the final heat treatment process. The measured results demonstrate consistent hardness distribution across the tested surface, ensuring durability during operation.
Carbide Network Grading
Carbide network grading was evaluated according to GB/T 1299-2000 Appendix A using deep etching with 2%–4% picrate alcohol solution. The carbide network was rated at Grade 1.0, meeting the specified limits for carbide non-uniformity as defined. The inspection was completed on 15 August 2023, confirming that the ring die satisfies all metallurgical quality standards.
