Embodiment Construction

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

[0009] The invention includes by weight percentage: adding 0.5% of chromium, 0.3% of vanadium, 0.8% of carbon and steel as the balance.

[0010] Chromium in the present invention: element symbol Cr, silver-white metal, hard and brittle, belonging to group VB in the periodic table of elements, atomic number 24, atomic weight 51.9961, and density 7.20 g / cm;

[0011] Vanadium, element symbol V, silver-white metal, belongs to VB group in the periodic table of elements, atomic number 23, atomic weight 50.9414, body-centered cubic crystal composition.

[0012] In the present invention:

[0013] C (carbon) 0.8%, high carbon steel has good hardenability and wear resistance.

[0014] Cr (chromium) 0.5%: Chromium can significantly improve the strength, hardness and wear resistance, and at the same time, chromium can improve the oxidation resistance and corrosion resistance of s...

Abstract

The invention relates to a high elasticity and corrosion resistant band tape material, which comprises, by weight: 0.5% of added chromium, 0.3% of vanadium, 0.8% of carbon and the balance steel. The invention has the beneficial effects that: due to the adding of chromium (Cr) and vanadium (V), chromium can significantly improve the strength, hardness and wear resistance in constructional steel and tool steel, and can improve the oxidation resistance and corrosion resistance of steel; at the same time, as vanadium is an excellent deoxidizing agent of steel, the adding of 0.3% of vanadium in carbon steel can refine the grain structure, and enhance the strength and toughness; a carbide formed by vanadium and carbon also can improve the hydrogen corrosion resistance under high temperature and high pressure.

Description

technical field [0001] The invention relates to a measuring tape, in particular to the material of the measuring tape. Background technique [0002] The material of the tape measure is generally composed of C (carbon), Fc (iron). [0003] Due to the lack of Cr (chromium) and V (vanadium) content in the existing tape material, the strength, hardness and wear resistance of the tape tape are reduced during use. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a highly elastic and corrosion-resistant measuring tape material, aiming at solving 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 includes by weight percentage: adding 0.5% of chromium, 0.3% of vanadium, 0.8% of carbon and steel as the balance. [0007] Compared with the prior art, the beneficial effects of the present i...
