The Material Advantage of JARAY Forged Ring Die Blanks for Pellet Mill from China
at the heart of every JARAY Forged Ring Die Blank for Pellet Mill from China is premium raw material, with our specialization in X46Cr13 stainless steel setting us apart from ordinary suppliers. This martensitic stainless steel grade offers the ideal balance of hardness, wear resistance, and corrosion protection required for demanding pelletizing applications .
Precision-Controlled Chemical Composition
The chemical composition of our X46Cr13 material is precisely controlled to tight specifications: Carbon content between 0.45-0.49 percent ensures through-hardening capability; Chromium levels of 13.5-14.2 percent provide exceptional corrosion resistance and wear properties; and Nickel content of 0.20-0.40 percent adds crucial toughness to prevent chipping under high-stress conditions.
Verified Quality Through Spectrometer Analysis
When you specify JARAY Forged Ring Die Blanks for Pellet Mill from China, you receive material that has been verified through spectrometer analysis before any forging begins. This fundamental quality control step ensures that every blank possesses the inherent potential to become a world-class ring die.
The Forging Process Behind JARAY Forged Ring Die Blanks for Pellet Mill from China
The transformation of raw steel into a JARAY Forged Ring Die Blank for Pellet Mill from China involves a sophisticated multi-stage forging process designed to enhance the material's natural properties. Our process begins with uniform heating in state-of-the-art induction furnaces, ensuring consistent temperature throughout the billet and preventing surface defects that could compromise the final product.
High-Tonnage Hydraulic Pressing for Superior Density
High-tonnage hydraulic presses then upset the heated billet, a critical step that breaks down cast structures, closes internal porosity, and increases material density. This initial forging operation creates the foundation for the exceptional mechanical properties that characterize JARAY Forged Ring Die Blanks for Pellet Mill from China.
Precision Ring Rolling for Optimal Grain Flow
The upset billet is then pierced to create the rough ring shape before undergoing the most critical operation in our production sequence: precision ring rolling on CNC-controlled radial-axial ring rolling mills. During this process, the wall thickness is progressively reduced while the diameter expands, creating a seamless ring with grain flow perfectly aligned to resist the circumferential stresses of pellet extrusion.
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.
