Ultra-Low Oxygen & Carbon | Vacuum Arc Remelted (VAR) | Precision Engineered for Extreme Environments
Product positioning: Ultra high end material solution
Product Overview
Engineered for industries where material purity dictates performance, our High Purity Iron Billet achieves 99.98% Fe content through Vacuum Arc Remelting (VAR) technology – a benchmark for semiconductor equipment, cryogenic systems, and advanced nuclear reactors. With oxygen levels <10 ppm and carbon content ≤0.005%, this billet eliminates grain boundary contamination, enabling ultra-high vacuum compatibility and radiation resistance unmatched by conventional iron.
Differentiated Content Architecture
1. Technological breakthroughs and process innovation
VAR Process Advantages:
Step 1: Electrode preparation with electron beam cold hearth refining (EBCHR) to remove volatile impurities.
Step 2: Vacuum arc melting under 10⁻⁴ mbar pressure to eliminate gaseous inclusions.
Step 3: Directional solidification control for columnar grain alignment .
Certified Superiority:
ASTM E1409 compliance for interstitial element analysis.
Third-Party Data: Hydrogen embrittlement resistance >500 hours (per ASTM F1624).
2. Exclusive application scenarios and performance validation
Semiconductor Manufacturing:
Vacuum chamber liners & EUV lithography components – zero outgassing under 10⁻⁷ Torr.
