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..

Welding/Soldering

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

Folded

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.

Bend

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.

Mechanisation

Good, without special precaution.

Stock Program

  • Large range of densities and formats from 6mm to 50mm.
  • Check our stock in the warehouse for each supply, as if delivery period for formats not available.
  • We also serve parts of sheet, cut in multiples lengths of 1000mm maintaining the width.
  • In thickness from 4 to 60 mm we have sheets with finished superficial shot blast and prime.
  • Oxycut of tailor-made pieces from 6-8 mm thickness.

* The specifications are illustrative. For each supply we offer a certificate with the datum of the shipment delivered.
