5CrNiMo steel is a traditional low-alloy hot-work tool steel that has been widely used in various applications, particularly for forging dies. It has excellent hardenability, good toughness, and moderate strength at elevated temperatures, though it has some limitations in very high-temperature or high-wear applications. 5CrNiMo is a grade under China’s GB\/T standard, with equivalent grades including American AISI<\/mark><\/a> L6<\/mark><\/a>, Japanese JIS SKT4, and German DIN W-Nr. 1.2713 and 1.2714.<\/p>\n\n\n\n

Note:<\/strong> 5CrNiMo steel can be hardened by cooling in air, but it is prone to forming white spots, so it should be cooled slowly after forging. For large forgings, they must be held in a furnace at 600\u00b0C until the temperature is uniform, then slowly cooled to 150-200\u00b0C, and finally cooled in air. For larger forgings, tempering should be carried out immediately after cooling to 150-200\u00b0C.<\/p>\n\n\n\n
