Selection FAQ
- What does head stock require?
- Good ductility and uniform thickness tolerance — usually 304 / 316L. The material is subsequently spun or pressed, so negative thickness deviation must be held tighter than for ordinary sheet.
- Can you supply over-width?
- Beyond standard width it needs welding or a wider feedstock; send the head diameter and forming process for assessment.
