Steatite Ceramic Socket Insulator 190 MPa Flexural Strength 2.8 g/cm³ Density for Welding Heat Treatment
Steatite ceramic tube socket designed for high-performance electrical insulation applications. We provide complimentary process design and validation services.
Ceramic components for flexible pad and channel heaters in pre and post-weld heat treatment operations. Ideal for welding processes, stress-relieving, pre-heating, post-heating, and other resistance-heating environments.
- High resistivity for superior electrical insulation
- Moderate mechanical strength with 190 MPa flexural strength
- Excellent electrical properties with 18 kV/mm dielectric strength
- Poor heat conductivity (thermal insulator)
- Good resistance to thermal shock
- Low coefficient of thermal expansion (7.7×10⁻⁶/°C at 40-400°C)
- Excellent mechanical stability
