Typical application

Stretch on the useful life of the machinery and reduces the stop of the maintenance service. Applicable en those cases that, in addition to the requirement of a good weld ability and/or  high resistance to wear, it is requested a better shaping  and good toughness like: building of dump truck, bulldozers, dust conductions, mining machinery, movement equipment of ground, In gear assembly and sand and gravel plant sieve, crusher linings, pinion gear, gear assembly, bisifines, dust conductions, cyclons, trommels...

Supply status

Sheet produced based in its chemical composition and its cool dawn and draw stainless..


It does not present any problem using a basic coating electrode . It is not recommended to preheat beyond 150/200ºC to maintain its tenacity.


It can be folded and shaped in cold keeping in mind that the folded axis should be upright in the sense of lamination and the folded radius is minimum six times the thickness of the sheet. It is recommended to grind or sharpen the welding notch produced by the oxycut in the zones closer to the folder before knocking to shape in cold. We suggest doing a previous essay.


Minimum bend diameter: 60 times sheet thickness.

Transformation (Hot deformation)

The characteristics in toughness take down when there is a heating over 200ºC. To regenerate the toughness, it is required a new cool down and drawn stainless. It not results appropriate for hot forming or in structures that require elimination of tautness.


Good, without special precaution.
