Processing & Safety
- Machinability:
- C17300 (Pb-added) is engineered to excel in CNC turning/milling, delivering a superior surface finish of Ra < 1.6 μm.
- C17200/C17500 require precision carbide tools for cutting, ensuring high accuracy and performance.
- Heat Treatment:
- Solution annealing is performed at 760-790°C with rapid cooling to achieve optimal results.
- Aging is carried out at 315-345°C for 2-3 hours to reach peak hardness, ensuring maximum durability and performance.
- Safety Compliance:
- Our operations are OSHA-compliant, with stringent Be dust control measures ensuring levels remain below <0.2 μg/m³, prioritizing safety.
- RoHS/REACH exemptions for Pb in C17300 (EU Directive 2011/65/EU) underline our commitment to compliance and environmental responsibility.
