Until now the material strength has growth rapidly. Commonly, the strength of material is depend on the dimension. A material need a strength too, one of the strength is impact strength and the tensile strength. To maximized the strength of material is added the layer of material with the same thickness, same dimension and compactible heat treatment. The specimens had make for two testing are impact and tensile testings. The impact testing show that the biggest point is thickness 2,5 mm with non treatment 89,75 Joule and the smallest point is to be thickness 2,0 mm with quenching 62,12 Joule. The tensile testing show that biggest point is thickness 2,5 mm with non treatment 89,75 Joule and the smallest point is to be thickness 2,0 mm with quenching 62,12 Joule. The tensile testing show that biggest point is thickness 2,0 mm with non treatment 9075 kgf and the smallest point is to be thickness 1,25 mm with quenching 7262,5 kgf.
