Abstract
FIELD: metallurgy. SUBSTANCE: steel has following components, mass %: carbon - 1.6 - 1.85; molybdenum - 5.6 - 6.5; chrome - 4.3 - 5.3; vanadium - 4.5 - 5.3; niobium - 0.2 - 0.5; silicon - 0.2 - 0.5; manganese - 0.15 - 0.55; iron - the rest. EFFECT: increased steel firmness and thermal shock resistance. 2 tbl
Description
Изобретение относится к стали для режущего инструмента или для штампов холодного деформирования. The invention relates to steel for a cutting tool or for cold forming dies.
Целью изобретения является повышение твердости и теплостойкости стали. The aim of the invention is to increase the hardness and heat resistance of steel.
Химический состав исследованных плавок предлагаемой и известной сталей и их свойства приведены в табл. 1 и 2. The chemical composition of the studied heats of the proposed and known steels and their properties are given in table. 1 and 2.
Предлагаемая сталь получается методом порошковой металлургии. The proposed steel is obtained by powder metallurgy.
Оптимальное содержание углерода в стали удовлетворяет следующему соотношению, C 0,06 (Mo) + 0,21 (V) + 0,13 (Nb) + + (0,30-0,35). The optimum carbon content in the steel satisfies the following relationship: C 0.06 (Mo) + 0.21 (V) + 0.13 (Nb) + + (0.30-0.35).
Как следует из табл. 2, твердость после термообработки, а также теплостойкость предлагаемой стали выше, чем у известной. Несмотря на высокое содержание углерода после отжига сталь обладает хорошей обрабатываемостью (НВ не более 230). As follows from the table. 2, the hardness after heat treatment, as well as the heat resistance of the proposed steel is higher than that of the known. Despite the high carbon content after annealing, the steel has good machinability (HB no more than 230).
