<\/figure>\n\n\n\nSince his die structure is an upper-and-lower die design with a stepped surface, it requires good toughness; the die as a whole uses a significant amount of steel, so the cost cannot be too high; various types of stainless steel are forged at high temperatures, which places extremely high demands on the die steel\u2019s heat resistance and thermal stability, so a die steel with excellent heat resistance must be selected.<\/p>\n\n\n\n
\u00a0Currently, H13 begins to deform, experience corner collapse, and develop cracks after about 1,000 cycles. This is because H13 has poor heat resistance; the mold is annealed during use, causing a drop in hardness and a loss of red hardness, which leads to failure in the form of deformation, corner collapse, and cracking. Improving the heat resistance of the mold steel is key, so I recommended the heat-resistant steel 8433<\/a><\/strong> at the time.<\/p>\n\n\n\n The heat resistance and stability of 8433 die steel<\/strong> are 2\u20133 times that of H13, with a hardness of HRC 50\u201354. Throughout its service life, the die will not anneal, its hardness will not decrease, and its red hardness is guaranteed. This eliminates the two major persistent problems of die collapse and cracking. It is particularly worth emphasizing that the service life of 8433 dies does not decrease after repair; even if a die is repaired to the point of scrapping, the hardness on the back surface will not decrease. A customer used this steel to hot-forge deep-drawn 45 steel products. After four surface regrinding operations, the mold\u2019s service life remained unchanged, with each cycle lasting 10,000 strokes.<\/p>\n\n\n\n 8433 is a proprietary heat-resistant steel developed by Yuhui Mold Steel. It far surpasses competing products in multiple performance metrics\u2014including high heat resistance, fatigue resistance, and thermal conductivity\u2014and its performance is second to none. Because 8433 prevents mold collapse and cracking, mold life is significantly extended, downtime for mold repairs is reduced, automated forging efficiency is maximized, and costs are drastically lowered. Currently, over 100 companies\u2014including Valeo, South China Precision Forging, and Sanlian Forging\u2014as well as Fortune 500 companies, publicly traded firms, and large and medium-sized automotive parts manufacturers\u2014are using it.<\/p>\n\n\n\n From June 6, 2025, to the present\u2014a full year has passed\u2014Mr. Ying\u2019s willingness to make frequent purchases clearly indicates that the service life of 8433 heat-resistant steel is definitely longer than that of H13. Since he needs fewer mold repairs and his efficiency has improved, he continues to place orders\u2014and in bulk.<\/p>\n\n\n\n Repeat orders from long-time customers are always a pleasure. After a year has passed, I feel it\u2019s time to document this case.<\/p>\n\n\n\n When hot-forging dies suffer from collapse or cracking, using 8433 die steel<\/strong> is even more satisfying than eating braised pork!<\/p>\n\n\n\n *************<\/p>\n\n\n\n![\"\"](\"https:\/\/www.wudejiansteel.com\/wp-content\/uploads\/2026\/07\/8433\u6a21\u5177\u94a2\u505a\u7684\u70ed\u953b\u6a21\u5177\uff0c\u964d\u97624\u6b21\uff0c\u6a21\u5177\u5bff\u547d\uff0c\u6bcf\u4e00\u6b21\u90fd\u57281\u4e07\u6a21\u6b21\u4ee5\u4e0a-2.jpg\")
