Embodiment 1

[0040] The preparation of embodiment 1 alloy

[0041] The composition of the carbon alloy is (by weight %):

[0042] 0.28% carbon;

[0043] 1.0% manganese;

[0044] 0.13% phosphorus;

[0045] 0.17% sulfur;

[0046] 1.00% silicon;

[0047] 0.06% aluminum;

[0048] 0.01% nitrogen;

[0049] 0.61% tellurium;

[0050] 0.05% niobium;

[0051] 0.40% copper;

[0052] 0.40% nickel;

[0053] 1.00% molybdenum;

[0054] 0.2% vanadium;

[0055] 0.0055% antimony;

[0056] 0.040% titanium:

[0057] The rest is iron and unavoidable impurities.

[0058] 30 kg of a steel material having the above composition was melted in a high-frequency vacuum furnace, followed by casting in which the cooling rate was 1.2° C. / min to form an ingot. The ingot was kept at 950°C for 10 hours and then at 500°C for 90 minutes. Thereafter, hot forging was performed using a 500-ton hammer forging machine, thus producing carbon alloy 1.

Embodiment 2

[0059] The preparation of embodiment 2 carbon alloy

[0060] Carbon alloy 2 was prepared in the same manner as in Example 1 except that molybdenum was not used.

Embodiment 3

[0061] The preparation of embodiment 3 carbon alloy

[0062] Carbon alloy 3 was prepared in the same manner as in Example 1 except that antimony was not used.

Abstract

The invention relates to a carbon alloy. The carbon alloy comprises the following components (in percentage by weight): 0.25%-0.29% of carbon, 0.10%-1.20% of manganese, 0.09%-0.13% of phosphorus, 0.10%-0.19% of sulfur, 0.60%-1.00% of silicon, not more than 0.09% of aluminum, not more than 0.01% of nitrogen, 0.45%-0.83% of tellurium, 0.04%-0.07% of niobium, not more than 0.50% of copper, 0.05%-0.60% of nickel, 0.2%-2.00% of molybdenum, 0.2%-0.4% of vanadium, 0.0030%-0.0065% of antimony, 0.010%-0.050% of titanium and the balance of iron and inevitable impurities. The carbon alloy disclosed by the invention has enhanced Rockwell hardness and can be widely used for production.

Description

technical field [0001] The invention relates to the field of metals, in particular to a carbon alloy. Background technique [0002] Carbon alloys are the most widely used alloys and are widely used in carbon steel and cast iron. However, due to the increasingly high requirements for alloys, some current alloys can no longer meet the requirements. Contents of the invention [0003] The object of the present invention is to provide a carbon alloy. [0004] In order to realize the purpose of the present invention, the present invention provides a kind of carbon alloy, the composition of described carbon alloy is (by weight %): [0005] 0.25% to 0.29% carbon; [0006] 0.10% to 1.20% manganese; [0007] 0.09% to 0.13% phosphorus; [0008] 0.10% to 0.19% sulfur; [0009] 0.60% to 1.00% silicon; [0010] ≤0.09% aluminum; [0011] ≤0.01% nitrogen; [0012] 0.45% to 0.83% tellurium; [0013] 0.04% to 0.07% niobium; [0014] ≤0.50% copper; [0015] 0.05% to 0.60% nickel;...
