Problems solved by technology

However, the above-mentioned steels are very expensive to manufacture
[0004] In addition, South Korea and foreign countries mainly use SNCM26V (SNCM616V) as the piston of rock crusher components, which is expensive, and requires long-term carburization treatment (more than 4 days) and low-temperature treatment of low-carbon Ni-Cr-Mo steel to ensure High hardness on the outside and high toughness on the inside, chisels and drills ensure high hardness by quenching and tempering SCM440 or medium-high carbon Ni-Cr-Mo steel, making them impact-resistant and wear-resistant, but their lifespan is the same as that of The price cannot meet the requirements, and these improved steels are currently difficult to be widely used in te

Embodiment

[0074] Table 1 shows the chemical composition of the invention steel of the present invention and the conventional steel of the prior art.

[0075] Invention steels A, B, C, D, E, and F are molten steels obtained by mixing and melting pure iron and scrap iron in a 60-ton electric furnace, refining and vacuum degassing, while invention steels G, H, I, J, K, L, M, N, O, P, Q Melt pure iron and scrap iron in a 3-ton electric furnace and refine them to obtain molten steel.

[0076] Inventive steels B, C, G, L, M, and N contain: 0.26-0.36% by weight of C, 1.6-2.2% by weight of Si, 0.5-1.0% by weight of Mn, 1.4-2.4% by weight of Cr, 0.01- 0.05% by weight of Ni, 0.01-0.4% by weight of Mo, 0.005-0.04% by weight of Al, 0.05-0.1% by weight of V, 0.0025-0.02% by weight of N, 0.01-0.1% by weight of Nb, 0.0005-0.01% by weight % Ca, the remainder being Fe and unavoidable impurities.

[0077] Invention steels A and E are made of molten steel with the above components and composition ranges...

Abstract

An impact-resistant and wear-resistant high-elasticity and high-strength steel, wherein the steel contains 0.26-0.48 wt% C, 1.4-2.5 wt% Si, 0.5-1.0 wt% Mn, 1.4-2.4 wt% % Cr, 0.01-0.1% by weight of Ni, 0.01-0.5% by weight of Mo, 0.005-0.04% by weight of Al, 0.05-0.1% by weight of V, 0.0025-0.02% by weight of N, the rest is Fe and unavoidable of impurities. The impact-resistant, wear-resistant high-elasticity and high-strength steel of the present invention has high hardness, high strength, high toughness and high elasticity, and the weldability, low-temperature tempering resistance and high-temperature tempering resistance, hardenability, Mechanical properties such as wear resistance, impact toughness, and tensile strength are excellent, so when used under severe conditions, the mold life and component life are much longer than conventional steels.

Description
