Frequently Asked Questions
Q1: How to verify ASTM B409 compliance?
A: Requires three key documents:
① Melt analysis report (with PMI testing)
② Grain size rating certificate (ASTM E112)
③ Third-party SGS material certification
Q2: Recommended machining parameters?
A: Optimal settings:
- Turning: 25-35 m/min cutting speed, 0.15 mm/rev feed
- Drilling: Carbide drills at 500-800 rpm
Critical: Use water-based cutting fluids with <50 ppm chloride content
Q3: Key welding procedure qualifications?
A: Per ASME IX requirements:
- Filler metal: ERNiCrFe-3 wire
- Interpass temp: ≤150°C
- Post-Weld Heat Treatment: 899°C±14°C with 2-hour soaking
