Propiedades mec\u00e1nicas<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">6CrW2Si steel possesses relatively high toughness, high as-quenched hardness, a certain degree of high-temperature strength, and high fatigue strength. It exhibits slight temper brittleness when tempered in the range of 300-350\u00b0C. The hardness can reach 54-56 HRC after tempering at 250\u00b0C, and 50-52 HRC after tempering at 450\u00b0C. This steel&#8217;s resistance to tempering and its wear resistance are slightly superior to those of 5CrW2Si steel, but its toughness is comparatively lower.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Chromium-tungsten-silicon (Cr-W-Si) series steels demonstrate high sensitivity to decarburization, and their quenching deformation is difficult to control. Under abrasive wear conditions, they show insufficient wear resistance, and their impact toughness is lower than that of impact-resistant steels containing Molybdenum (Mo) and Nickel (Ni).<\/p>\n\n\n\n<h2 id=\"h-6-applications\" class=\"wp-block-heading\">6. Aplicaciones<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">6CrW2Si steel is often used to manufacture heavy-duty stamping dies and cold-pressing dies where the failure modes are wear and collapse, or for manufacturing tools and dies that are subjected to impact loads and require high wear resistance, such as pneumatic tools, impact dies, cold shearing blades, blanking and trimming dies, and tools for air hammers.<\/p>\n\n\n\n<h2 id=\"h-7-equivalent-grades\" class=\"wp-block-heading\">7.
