General specifications*

C ≤ 0,26. Mn ≤ 1,70. Si ≤ 0,70. P ≤ 0,030. S ≤ 0,015. Cr ≤ 1,00. Ni ≤ 0,70. Mo ≤ 0,50. B ≤ 0,004.
Carbono equivalente ≤ 0,57. Rm≥ 1.400 N/mm2. ReH≥ 1.200 N/mm2. A ≥10 %. Dureza Brinell415/500Hb.

Typical application

Vehicle boxes that support impacts and rust made of abrasive materials and, in general, for metallic buildings that require high elastic limit and resistance to lighten structural weigh.

Supply status

Temperate, drawn stainless. Produced by water cool dawn and drawn stainless.

Edge

It can be cut by all the classic procedures (gas, plasma, water, laser).
The thickness from 4 to 10mm don’t need preheat if the oxycut operations be completed in a over temperature of 10ºC (steel temperature). On the contrary, we recommend to preheat from 100ºC to 150ºC.

Welding/Soldering

Thanks to its low contain carbon chemical composition; it has a very good aptitude to soldering.
It can be weld by conventional procedures like submerged-arc welding, manual welding with electrodes or thread MIG, MAG, TIG. The energy of the welding should be controlled between 5 and 15KJ/cm.
We recommend maintaining a maximum temperature of 200ºC. It doesn’t need a preheat in thickness from 4 to 10mm.

Folded

Folded aptitude: minimum R=5x thickness in longitudinal sense.
Good aptitude to fold because of its mechanical characteristics and chemical composition with a very low contain of phosphorus and sulfur.

Transformation

It’s not recommended doing it during the hot transformation given that (because) reduces the mechanical properties.

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.
