Processing & Safety
- Machinability:
- C17300 (Pb-added) is unparalleled in CNC turning/milling, delivering a surface finish with Ra < 1.6 μm.
- C17200/C17500 necessitate carbide tools for achieving precision cutting.
- Heat Treatment:
- Solution annealing is performed at 760-790°C followed by rapid cooling.
- Aging process occurs at 315-345°C for 2-3 hours to attain peak hardness.
- Safety Compliance:
- Handling complies with OSHA standards ensuring Be dust control is maintained at <0.2 μg/m³.
- RoHS/REACH exemptions apply for Pb in C17300 under EU Directive 2011/65/EU.
