6517 silicon manganese alloy is a compound deoxidizer commonly used in steelmaking. In the process of steelmaking, the silicon and manganese in the silicon manganese alloy can combine with the oxygen in the steel to form a stable oxide, so as to remove the oxygen in the steel and improve the purity of the steel. The effect of this deoxidizer is better than that of ferro silicon and pure silicon, because the manganese in the silicon-manganese alloy can promote the deoxidation effect of silicon, making the deoxidation reaction more complete.
6517 silicon manganese alloy can also be used as an alloy additive to improve the properties and strength of steel. Adding a certain amount of silicon manganese alloy to the steel can increase the strength, hardness, wear resistance, tensile strength, yield point and elongation of the steel, and also improve the corrosion resistance and high temperature performance of the steel. This alloying makes silicon-manganese alloy an indispensable additive in steel production.
6517 silicon manganese alloy is also a reducing agent for the production of low carbon ferro manganese and the production of metal manganese by electrosilicothermal method. In the smelting process, the silicon manganese alloy can form eutectic with other elements, improve the reduction conditions, promote the reduction of manganese and silicon, and reduce the carbon content of the alloy.
The strength of 6517 silicon manganese alloy is significantly higher than that of pure iron, and it also has a higher strength than low carbon steel. The addition of silicon and manganese made the strength and hardness of the alloy significantly improved.
The hardness of 6517 silicon manganese alloy is generally between HRC55 and 60, and its wear resistance is excellent, which is dozens of times that of ordinary steel, and can be used in extreme environments for a long time.
The alloy has good corrosion resistance and can resist the erosion of corrosive media such as atmosphere, water, acid and alkali. At the same time, the silicon and manganese elements in the alloy can form a dense oxide film at high temperature, which effectively prevents the oxidation reaction, so it has good oxidation resistance.
6517 silicon manganese alloy has excellent stability in high temperature environment, and can work in high temperature environment above 500℃ for a long time.
6517 silicon manganese alloy has good machining performance, easy to machining and forming.
