• Industrial: Plastic injection molding components, die-casting cores, high-stress fittings.

Why Choose YICHOU for Your 15-5 PH Components?

1. Material-Specific Expertise: We understand the gummy nature of 15-5 PH in its annealed state and employ optimized tool paths, cutting tools, and coolants to prevent work hardening and ensure superior chip evacuation.

2. Dimensional Stability Management: Our machining process is designed to account for the minimal, predictable dimensional shifts during aging, ensuring parts meet final print tolerances.

3. Quality Assurance: Every part is meticulously inspected. We provide certified material test reports (CMTRs) and first article inspection reports (FAIR) per AS9102.

4. Seamless Process: We handle the entire workflow—material procurement, machining, heat treatment coordination, finishing, and final inspection—simplifying your supply chain.

Frequently Asked Questions (FAQ)

Q: Is 15-5 PH stainless steel magnetic?
A: Yes, 15-5 PH is magnetic in the hardened condition, which is important for certain applications.

Q: What is the difference between 15-5 PH and 17-4 PH?
A: While similar, 15-5 PH offers better transverse toughness and more consistent mechanical properties across large sections, making it preferable for highly critical applications.

Q: Do you provide the heat treatment?
A: We manage the entire process. We partner with NADCAP-accredited heat treat facilities to ensure your parts are treated to exact specifications, and we include all certifications.

Q: Can you machine 15-5 PH from its hardened condition?
A: It is possible but not recommended due to extreme tool wear and the risk of introducing stress. Our standard and most cost-effective process is to machine in the annealed state and then age.

Q: What file formats do you accept for a quote?
A: We accept all major CAD formats: STEP, IGES, SLDPRT, X_T, and DWG/DXF drawings.
