The simplest way to determine H13 material is to check the original workpiece markings or Certificate of Materials (COA) and perform rapid composition verification using a handheld XRF spectrometer. This method achieves efficient and accurate determination without complex equipment.
1. Simplest Operating Procedure (No Professional Metallography Required)
Steps Operating Instructions
① Check Number and Markings: Check the surface of the hot runner for serial numbers, stamps, or labels, such as "H13," "4Cr5MoSiV1," or "SKD61" (Japanese standard equivalent).
② Retrieve Original Data: Contact the supplier or retrieve the BOM list to confirm whether the material is H13.
③ Rapid Spectroscopic Verification: Use a handheld XRF spectrometer for on-site testing to confirm key elements such as Cr≈5.3%, Mo≈1.3%, and V≈1.0%.
Practical Advantages: These three steps can be completed within 10 minutes, avoiding the time-consuming process of disassembly or sending for testing.
2.Why are these methods simpler?
No Metallographic Sample Preparation Required: Eliminates complex processes such as cutting, grinding, and etching.
Unaffected by Overheating: Spectroscopic analysis of the matrix composition requires only minor grinding to remove the oxide layer.
Intuitive and Reliable Results: Elemental content directly matches the H13 standard (GB/T 1299-2018), with an error of <0.1%.
Example: A Wuhan-based company confirmed H13 material within 3 minutes by scanning the workpiece's QR code and performing XRF verification.
3. Precautions:
Beware of Refurbished Parts Spoken as H13: Spectroscopic analysis is mandatory when original markings are missing or documentation is incomplete.
Distinguishing Between PM and H13: Powder metallurgy H13 has similar compositions but superior microstructure and a higher recycling price; note this in the comments.
Record Preservation: Take photos and archive the serial number and test data for recycling traceability and compliance auditing.
