Product details

M300 mold steel is a high-quality steel from the Aoguo Bailu brand, which is a martensitic chromium steel with a high carbon content. After heat treatment, the hardness is uniform, reaching 31-35HRC, and the mold never deforms. Due to its high chromium content (16%) and molybdenum content, the steel has good corrosion resistance and wear resistance, and has strong resistance to general chemical erosion, especially for P V. C product, more effective, easy to achieve mirror effect.
purpose
Suitable for molds that come into contact with chemically corrosive, transparent plastics, camera lenses, and other types of plastics. This steel is less transparent and easy to achieve the required high polishing and mirror polishing, making it a product of the same type of steel Suitable for plastic molds that come into contact with all chemicals, transparent plastic products, or molds that corrode objects.

heat treatment
Forging: Start forging at 1050 ℃ and return to the furnace at 850 ℃, then slowly cool along with the furnace.
Annealing: Air cooling at 800-850 ℃ or furnace cooling to 600 ℃, with a hardness of up to 285HB.
Quenching: cooled by oil or air at 1000-1050 ℃.
Tempering: 600-700 ℃ or 170-210 ℃. [1] After quenching, tempering should be carried out immediately, with a time reduction of 2 to 2.5 hours.
Welding: Welding can be done but should be avoided as much as possible.
