Slope protection brick mold has toughness, flatness, easy deformation, etc., can be removed to reduce the difficulty of releasing cement products, this slope brick mold in actual use will bring great convenience, no distortion, no damage while the choice of semi mold material, can increase daily production capacity, to better protect the duration of the successful completion of the slope a brick mold making process characteristics. Malleability has a lower forging deformation resistance, plastic, forging a wide temperature range, forging crack cold cracking and low precipitation tendency carbide network. 2. Annealing of the ball annealing temperature range, low annealing hardness and small fluctuation range, the ball higher. 3. Cutting large machinability, tool, low loss, low surface roughness. 4. Oxidation, anti-oxidation when heated to high temperatures pregnant decarbonization sensitivity is good, decarbonization slow the heating medium is not sensitive to small pitting tendency. 5. After quenching hardenability and has a uniform high surface hardness. 6. Hardenability after quenching can get deeper hardened layer, using relaxation quenching medium can be hardened. 7. Deformation hardening conventional quench cracking tendency of small volume change, shape warping, distortion slight tendency to lower abnormal deformation. Conventional quench cracking sensitivity is low, quenching temperature and shape of the workpiece is not sensitive. 8. Can be grinding wheel is relatively small loss, no grinding burn limit the amount of large, quality and cooling conditions on the wheel is not sensitive, less prone to injuries mill grinding cracks.
