Typical application

The combination of the lower alloy chemical composition and an appropriate treatment process get this great toughness steel, appropriate in applications where in addition to wear resistance, it is necessary resistance and tenacity. With possibilities of extensive application like conveyor building, mining machinery, bulldozer, movement equipment of ground and mechanical manipulation. Quarry, mining, lorry boxes, dumper, washing sites, mineral classification, etc.

Supply status

Drawn stainless and temperate.

Blowtorch edge

It can usually be oxicuted using the conventional practices of blowtorch cut and typical cut parameters.
To minimize the risk of break, is recommended to cut by blowtorch using preheat between 100 to 150ºC.


During the soldering, the temperatures between the passes should not exceed 200ºC. When the preheat its necessary, we advise that the temperature does not surpass 150ºC.
The following minimum temperatures of preheating are recommended:

Thickness of the sheet mmRange Power Heat

≤ 12,52,0 - 3,55050
12,5 - 302,0 - 3,550100
30 - 402,0 - 3,550150

Welding consumables

Can be weld in normal terms, using consumables that supply a low content of hydrogen in the metal weld and that have been dry completely according with the advises of the supplier. The manual MIG metal-arc and the welding of the submerged-arc, are recommended processes for the soldering of this material. You can select consumables on the basis according If the weld metal will be exposed to the abrasion or not. We can use low resistant weld metals only in the absence of abrasion in them and we should use consumables that give deposit still greater   for more demanding situations.

Pin welding

Can be weld by pins without preheating. When is required anti rust agent, can be assembled with soldering better than other expensive drill and bolt systems.


It can be folded in cold. It is recommended to upright in the sense of lamination. Bend radius minimum 10 times the thickness of it. The notches produced during the blowtorch edge, etc. should be eliminated from the closeness of the folded before any cold shape.


Like with the majority of the high hardness metals should be taken caution. The drill conditions will change according to the typical application and attention must be devoted to the suitable speeds of the drill, to the rotational speeds and to the required drill diameters.
Are set out the following examples and some of the areas where is important to pay attention in the drill and drill processes selection.
Can be used high speed armored drill. For 14mm thermoformed drills should be employed a rotator speed of 160-200 rpm and a 0,12mm/revolutions supply, would be the appropriate when using an appropriate cooling. For a geometric bore into, we should use a slow fluted though plate propeller and an end angle of 130ºC.
Can be also used modern metal short hole insert carbide adjustable drill. In such circumstances attention must be devoted to the engineering, fixation and stiffness rules. In general the correct drill speeds for holes of 20mm of diameter would be between 6-8mm for minute considering a normal and rational velocity and the perforation diameter, with supply types of 0,11mm per revolution orders.


Not appropriate for hot shaping and for applications that require easing of tensions.
Do not warm over 200ºC.
