Iron based alloy has the function of good wear resistance, high temperature resistance, anti-oxidation and thermal shock resistance high hardness and strength in normal and high temperatures, excellent oxidation resistant to deoxygenize corrosion of compound medium, corrosion of high temperature gas, corrosion of chloride corrosion of strong deoxygenize medium. Mainly used it on manufacture, repair and pre-protection of all kinds of spare parts that are anti-oxidation, corrosion resistance, impact and strong wear in the fields of agriculture, chemical industry, metallurgy, mining and other industries.
