1.8433 mold steel is a type of mold steel with excellent resistance to tempering and softening, and its heat resistance is approximately 2-3 times that of H13. 1.8433 mold steel is a type of mold steel with excellent resistance to tempering and softening, and its heat resistance is approximately 2-3 times that of H13. And the carbon content of 1.8433 is below 0.4%, with good crack resistance performance; The Mo content of heat-resistant alloy is higher than 8418, with good heat resistance and stronger resistance to thermal wear.
Its high toughness and heat resistance make it very suitable for large hot forging molds, especially those used on friction presses with thousands of tons, such as crankshafts, connecting rods, and other large hot forging molds.
The 1.8433 die steel used for hot forging molds has a high cost performance ratio. The hot forging die is made of 1.8433 mold steel, which has a long service life and reduces the mold cost allocated to each component, resulting in improved production efficiency per unit time.
The characteristic of 1.8433 mold steel is its high-temperature softening resistance * *, and its heat resistance is 2-3 times that of H13. When used in hot forging molds, the mold can maintain high hardness for a long time without decreasing. The hot forging die made of 1.8433 mold steel is not easy to soften and crack, therefore, the service life of the die is long.
The secondary characteristics of 1.8433 mold steel are high thermal conductivity and fast mold heat dissipation; This feature can improve the heat resistance of the mold, and the mold will not crack, even if it is directly water-cooled; This is a characteristic that ordinary hot work mold steel does not possess.
