Abstract

The invention discloses an electrolytic nickel alloy material. The electrolytic nickel alloy material comprises chemical components including, by weight percent, 80 to 87% of nickel, 4 to 6% of titanium, 3 to 5% of carbon, 1.2 to 2.5% of iron, 0.3 to 0.9% of cobalt, 0.09 to 0.15% of silicon, 0.05 to 0.09% of phosphorus, 0.055 to 0.07% of sulphur, 0.2 to 0.6% of chromium, 0.14 to 0.77% of gallium,0.09 to 0.2% of strontium and 0.4 to 0.65% of rhenium. The material is quite easy and convenient to forge, multiple procedures are not needed, cost is low, the strength of the material approaches to that of actual application, and the material is quite suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to an electrolytic nickel alloy material. Background technique [0002] Nickel alloys are all alloys. Chromium-nickel stainless steel is the main stainless steel species that consumes nickel. Due to its excellent comprehensive performance, it is widely used, accounting for 60% to 75% of the total output of stainless steel. The growth of stainless steel production will drive the growth of nickel metal consumption. As the impact of the financial crisis subsides, the price of nickel returns to more than 20,000 US dollars, and the advantages of nickel-iron alloys in reducing the cost of stainless steel smelting are gradually reflected, and nickel-iron alloys occupy an important position in stainless steel raw materials. The existing electrolytic nickel alloy forging is extremely cumbersome and needs to go through multiple processes, the cost is high, and the strength has a large dev...
