CARINOX, S.A. amples its lines of business, adding the distribution of a new material (Steel) of extreme hardness and resistance.  Next we offer an ample technical information to you that it will facilitate the election of this material like solution for the necessities in situations in which the hardness of the material is essential.

SSAB SWEDISH STEEL is a steel company, Swedish, specialized in the production of steel plates with stop limits elastic and resistant to the wearing down products HARDOX, WELDOX and DOMEX its use is being increased due to its economic benefits in the use of such.

INTRODUCTION
In the last decades, modern plates antiwear away have gone increased their use to replace materials of smelting and steel of high content in carbon in situations of moderate wearing down.  Specially for public works and quarries the combination of life utility, resistance to breakage and the aptitudes in the factory have been superior.  Until recently the Maxima hardness available between 500 steel HARDOX Brinell was of.  A hardness that was not sufficient in extreme situations of wearing down.  For years, the Hardox-600 steel has been introduced in the market.  Giving a new alternative to increase the total economy of the end user.  In the present article, the Hardox-600 steel is presented/displayed and some applications of the real life are propose.

HARDOX STEELS
In most of the cases of wearing down, a material with greater hardness will have a greater life utility.  To obtain a greater hardness is not difficult.  In steel, the historical way to obtain a high hardness has be increasing the content of aleantes components, specially the carbon and the chromium.  The disadvantages of this procedure are that the material was cracked and broke with facility and in addition to work with this type of steel in the factory was very complicated.  In the steel plates HARDOX, the greater hardness it is reached through extremely efficient heat treatments.  Of this form the contents in aleantes components can be maintained very low and the hardness can be combined with other benefits.  One of the most important properties of the material ones antiwears away is the RESILIENCE.  While more stop is east better value is the resistance to breakage of the material.  In the figure the 1 resilience of Hardox-600 is compared with a smelting steel, which is used quite often as steel antiwears away.

APLICATIONS

Coverings for mills.
In many coverings of the walls of the mills, are used pieces of smelting made in steel to Manganese.  The steel to Manganese has the interesting property that elevates its hardness with the use.  Therefore, it increases his resistance to the wearing down.  A typical value for the steel to Manganese when it begins to use by first is of 260 Brinell and at the end of its life the the 550 hardness can reach Brinell.  Hardox-600 having guaranteed 600 Brinell throughout all its life utility, represents an alternative of greater life in good condition.  Another benefit is that the pieces made in Hardox-600 maintain their form whereas the changing geometry of the steel pieces to Manganese during its use some times can carry problems.

Blades in clamps of demolition and shears
For several years have been verified that the Hardox-600 steel, behaves of an excellent form using it as blades in the clamps of concrete demolition and in the shears.  Previously a material was used that after mechanizing it occurred a heat treatment him to reach a hardness of 500-600 Brinell.  The result was a hard material but with a low resilience.  When working the blade with certain efforts important notches and fisuration of the same ones took place.  With Hardox-600 these notches and fissures are disappear, obtaining themselves therefore a greater life utility of the blades.

IN THE FACTORY

Due to his under content in aleantes components, Hardox-600 very is adapted to make pieces antiwears away.  Ever since Hardox-600 makes in plates, one of the greater benefits is than the form wished for each specific application can be made.  In smelting steel, the geometry of the single piece can be changed if the amount of pieces to buy is quite great.  The tolerances in geometry are thus very superior with Hardox-600.  Comparing it with other hard materials as they are steel of smelting and steel of tools, Hardox-600 can very easily also be mechanized and be cut.  The best method of cut for the Hardox-600 steel, is the cut by water spurt.  This system of cut does not affect the structure of the steel because the calorific contribution is null, and the tolerances can even be similar a mechanized one.  Hardox-600 also can be welded, despite for heavy thicknesses is necessary to have special a well-taken care of one.
