Aluminum-containing high-speed steel (HSS-Al) is smelted by a method of carbon (Al) elements based on molybdenum high-speed steel and is designed to increase thermal hardness and wear resistance.
The performance of the aluminum-containing high-speed steel is similar to the cobalt-containing ultra-hard high-speed steel, the hardness of the heat treatment is HRC67 ~ 69, the anti-bending strength is 290 kg / square millimeters, the impact value is 2.3~3kg 1m/cm² The high-temperature hardness at 600°C is HRC54~55.
Aluminum-containing high-speed steel (HSS-Al) forging performance and excellent cutting performance, but grinding performance is lower than normal high-speed steel when grinding with white jade wheels, and superior to high-speed steel and high vanadium high-speed steel and high vanadium Cobalt high-speed steel.
The durability of the HSS-Al tool is similar to the cobalt-containing ultra-hard high-speed steel, 1 to 2 times higher than the ordinary high-speed steel, up to 3 to 4 times.
