Embodiment Construction

[0008] Below in conjunction with specific embodiment the present invention is described in further detail:

[0009] The invention comprises by weight percentage: 0.3% of vanadium, 1.2% of carbon, 0.15% of nickel and the balance is steel.

[0010] Vanadium in the present invention: element symbol V, silver-white metal, belongs to group VB in the periodic table of elements, atomic number 23, atomic weight 50.9414, and body-centered cubic crystal composition. Vanadium is an excellent deoxidizer for steel. Adding 0.3% vanadium to the steel can refine the structure and grain, improve the strength and toughness. Carbide formed by vanadium and carbon can improve hydrogen corrosion resistance under high temperature and high pressure. C (carbon) 1.2%, high carbon steel has good hardenability and wear resistance. Ni (nickel) 0.15%: Nickel can increase the strength of steel while maintaining good plasticity and toughness. Nickel has high corrosion resistance to acid and alkali, and h...

Abstract

The invention relates to a high toughness and corrosion resistant blade material. The blade material comprises the following components in percentage by weight: 0.3% of vanadium, 1.2% of carbon, 0.15% of nickel and the balance of steel. The high toughness and corrosion resistant blade material has the beneficial effects that due to the fact that vanadium is the good deoxidizer of steel after adding V (vanadium), and organization crystal grain can be refined by adding 0.3% of vanadium in carbon steel, so that the strength and toughness are improved; and corrosion resistance to hydrogen can be also improved in a high temperature and a high pressure for carbide formed by vanadium and carbon.

Description

technical field [0001] The present invention relates to a blade, in particular to the material of the blade. Background technique [0002] The blade material is generally composed of C (carbon) and Fc (iron). [0003] Due to the lack of V (vanadium) content in the existing blade materials, the blade toughness is slightly low during use, and hydrogen corrosion is easily formed at high temperatures. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a high-toughness, corrosion-resistant blade material, aiming to solve the above-mentioned problems. [0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: [0006] The invention comprises by weight percentage: 0.3% of vanadium, 1.2% of carbon, 0.15% of nickel and the balance is steel. [0007] Compared with the prior art, the beneficial effect of the present invention is: after adding V (vana...
