Weight saving and/or more resistant structures
Due to its high yield strength compared to classical steel (750 Mpa in average),
you can :

- reduce thickness of structure and make weight saving and/or
- support higher stresses and realise more resistant structures

Bending
PROCESSING Thanks to the quality of steel making process, TS 800 is easy to shape providing the
following conditions are respected :
▪ Dressing (or grinding) of the ridges caused by gas-cutting to limit the
hardened zones
▪ Sufficiently powerful equipment
▪ Respect of minimum forming radius

In hot conditions, TS 800 is unsuitable for hot forming at
a temperature higher than 600°C (1100°F)

Welding

The reduced carbon and alloying elements content of TS 800 allow welding in very
good conditions with excellent characteristics.

➢ Weld preparation
The preparation of joints and surfaces is most important, notably :
▪ Removing all traces of grease and water
▪ Grinding of cuts to remove any oxides, slag of grooves from cutting with
excessive oxygen pressure
▪ Grinding of any sheared edges, tears final drips
