Abstract

The invention discloses a carbon-containing nickel-iron alloy material. The carbon-containing nickel-iron alloy material is prepared from the following chemical components including, by weight, 20-30%of nickel, 65-75% of iron, 3-5% of carbon, 0.55-1.1% of cobalt, 0.08-0.2% of silicon, 0.04-0.08% of phosphor,0.035-0.09% of sulfur, 0.1-0.55% of chromium, 0.2-0.85% of gallium, 0.18-0.35% of strontium and 0.1-0.25% of rhenium. The carbon-containing nickel-iron alloy material is extremely convenient to forge, needless for multiple working procedures, low in cost and extremely suitable for industrial mass production, and the strength of the carbon-containing nickel-iron alloy material is close to practical application.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to a carbon-containing nickel-iron alloy material. Background technique [0002] Nickel-iron alloys are all alloys. Chromium-nickel stainless steel is the main stainless steel variety that consumes nickel. Due to its excellent comprehensive performance, it is widely used, accounting for 60% to 75% of the total stainless steel output. 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 carbon-containing nickel-iron alloy forging is extremely cumbersome and needs to go through multiple processes, the cost is high, and the str...
