Propiedades mec\u00e1nicas<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">9CrWMn steel is a low-alloy cold-work tool steel with high hardenability. The carbides formed by the W element constitute the hardening phase in the steel, resulting in high hardness and wear resistance after quenching and low-temperature tempering, while maintaining good toughness. This steel exhibits maximum bending strength and toughness when quenched at 800\u00b0C. Impact toughness reaches its lowest value when tempered around 300\u00b0C; therefore, tempering at this temperature should be avoided. The steel is sensitive to the formation of network carbide. Thus, appropriate forging should be performed during machining, and carbide refinement treatment is recommended.<\/p>\n\n\n\n<h2 id=\"h-6-applications\" class=\"wp-block-heading\">6.
