摘要:
Weld deposit compositions with improved abrasion and corrosion resistance are provided by balancing percent weights of Chromium (Cr), Titanium (Ti), Niobium (Nb), and Boron (B) to allow the Chromium content of the weld matrix to be minimally reduced during carbide formation. The result is an enriched Chromium matrix that has excellent corrosion resistance in combination with highly abrasion resistant dispersed carbides.

摘要:
Steels, in particular hot work steels having high toughness even for high thickness, including steels having long durability combined with mechanical, tribological and thermal properties for highly demanding applications, and steels which can achieve a very good environmental resistance and resistance to certain aggressive media combined with other relevant properties, are described. These steels may also be obtained at low cost. A method for the manufacture of steels having high thickness and manufacturing methods to shape the materials of the invention through several steps, including an additive manufacturing step to manufacture at least a part of an intermediate mold, a mold or a model, a Cold Isostatic Pressing (CIP) step, the elimination of the mold and densification among other steps, are also described.
