There are 5 major strengthening methods for tool<\/strong> steel<\/strong>, and all research and production revolve around these 5 methods.<\/p>\n\n\n\n

Solid solution strengthening with the addition of carbon, where carbon atoms are small and can dissolve into \u03b1 – iron, thereby improving the strength and hardness of steel.<\/p>\n\n\n\n

The substitution strengthening of alloys can change the grain arrangement structure of \u03b1 – iron, thereby increasing the stress field and improving the strength of steel, also known as defect strengthening.<\/p>\n\n\n\n

The purpose of adding alloy to tool\u00a0steel<\/a><\/strong>\u00a0is twofold: one is to improve hardenability, and the other is to enable carbon and alloy to form certain hard carbide structures, thereby increasing the strength and hardness of tool\u00a0steel<\/strong>.<\/p>\n\n\n\n

The third method is forging strengthening, which involves six sided forging, three forging and three pulling, and changing the grain arrangement to achieve a strengthening effect. The hot forging, cold forging, and cold extrusion of important parts all belong to this process.<\/p>\n\n\n\n

The fourth one is fine grain strengthening, which allows carbides to be distributed in a fine and uniform dispersed manner. This is the most ideal microstructure state, which can improve the strength of steel while maintaining high toughness. This is also the most ideal strengthening method. It is also a reinforcement method that R&D personnel dream of and strive for.<\/p>\n\n\n\n

The advanced processes of preheating treatment and powder metallurgy after forging tool<\/strong> Steel<\/strong> are all aimed at achieving this idealized organizational state. Your high hardness tool<\/strong> Steel<\/strong> is prone to corner breakage and cracking, and many of them are also due to the inadequate strengthening process.<\/p>\n\n\n\n

The fifth step is the final heat treatment strengthening of the mold, which is commonly referred to as quenching and tempering. This is the most effective way to change the structural state of steel and improve its strength.<\/p>\n\n\n\n

There is also a sixth reinforcement method, keep it a secret. This article will definitely be plagiarized by someone. If everyone says it out loud, it will be meaningless, and I will lose my value. You won’t call me a king anymore.<\/p>\n\n\n\n
