What is the role of cobalt in steel?
cobaltInfluence on steel structure and heat treatment?
(1) Cobalt, like nickel and manganese, can form a continuous solid solution with iron.
(2) Both cobalt and aluminum are elements that reduce the hardenability of steel.
(3) Cobalt is not a carbide forming element.
(4) Cobalt can inhibit and delay the precipitation and accumulation of other special carbide elements during tempering or use.
The effect of cobalt on the mechanical properties of steel?
(1) Strengthening the steel matrix can improve the hardness and strength of carbon steel in the annealed or normalized state, but it will cause a decrease in plasticity and impact toughness.
(2) The hot strength and high temperature hardness of special steel are significantly improved.
(3) Improve the comprehensive mechanical properties of maraging steel to make it have super toughness.
The effect of cobalt on the physical, chemical and process properties of steel?
(1) Improve the oxidation resistance of heat-resistant steel.
(2) Improve the saturation performance of the permanent magnet and improve the performance of the permanent magnet.
The application of cobalt in steel?
(1) Mainly used for high-speed steel, maraging steel, heat-resistant steel, precision alloy, etc., among which maraging steel can be used for the club face of golf clubs.
(2) Cobalt resources are relatively scarce and expensive in the world, and are generally used in high value-added alloys, such as superhard high-speed steel.
