USE OF AN IRON BASED ALLOY FOR POWDER-METALLURGICAL PRODUCTION OF PARTS WITH HIGH STABILITY AGAINST CORROSION, HIGH RESISTANCE TO WEAR, AS WELL AS HIGH TENSACITY AND COMPRESSION RESISTANCE, IN PARTICULAR FOR MATERIAL TREATMENT

摘要

USE OF BASIC IRON ALLOYS FOR POWDER-METALLURGICAL PRODUCTION OF PARTS WITH HIGH ANTI-CORROSION RESISTANCE, HIGH RESISTANCE TO WEAR AS WELL AS HIGH TENACITY AND HIGH RESISTANCE TO COMPRESSION, ESPECIALLY FOR THE ELABORATION OF PLASTIC WITH PORCOSURE OF 16 0 - 29.0, MOLYBDENUM 0.4 - 2.5, WOLFRAMIO 0.3 - 2.0, VANADIO 3.0 - 10.0, TITANIUM UP TO 5.0, ALUMINUM UP TO 1.0, BORO UP TO 0.05 , NITROGEN 0,01 - 0,18, NIOBIO UP TO 5,0, IRON AND IMPURITIES OWN OF THE ELABORATION AS A REST, BEING THE VALUE, FORMED BY (CR- -13) + 4.4 X (V-3) + 2 X (NB) + 4.2 X (TI) GREATER THAN 8.8 AND THE MINIMUM CARBON CONTENT OF THE ALLOY RESPONDS TO THE CMIN RELATION = 0.3 + (CR-13) X0.06 + (2X MO + W ) X 0,03 + (VX 0,24) + (NBE THAT THE METRIC SHOWS AFTER THE SETTING AND THE ACTIVATION OF A CHROME CONTENT OF AT LEAST 13% AND THE CARBIDE CONTENT IS OF AT LEAST 25% OF THE VOLUME, BEING THICKNESS OF CARBIDE GRAIN UNDER 14 (MU) MY AND AT LEAST 5% THE CARBIDE VOLUME IS FORMED AS MC CARBIDE.
