FAQ Section
Q: Can you adjust manganese content for improved machinability?
A: Yes – We tailor Mn levels (0.05-0.5%) while maintaining ≤0.008% phosphorus.
Q: Do you offer anti-friction coatings for pattern molds?
A: Optional graphite-based coatings reduce sticking by 70% (additional 2-day lead time).
