HOLLOW BARS
ELG Carrs Stainless Steels have the most comprehensive range of hollow bar sizes offered to the world market place.
We manufacture our product from quality-forged bars either by trepanning and subsequent machining out of inside diameter or by deep hole boring for longer lengths.
Hollow bars can be supplied in random lengths or cut to suit an individual component.
Machined outside and inside diameters allow tolerances to be supplied, as described:
- Finish outside diameter — machined to tolerance (-NIL+2mm) 250CLD
- Finish internal diameter — machined to tolerance (+NIL-?mm) 1.6 ra
- Alternatively honed internally to H8 tolerance (+0.000”-0.002”)
Material is offered in grades as listed below:-
