Problems solved by technology

[0003] Hardware equipment mainly includes most of the metal parts or combined parts on the market. Most of the hardware equipment is composed of alloy steel; abrasiveness, high strength and other properties, but most of the alloy steels on the market are difficult to guarantee good wear resistance when their strength or hardness is improved. On this premise, the alloy steel is limited Application range

Abstract

The invention discloses combined alloy steel which comprises the following components by weight percent: 0.08-0.085% of V, 0.15-0.165% of Ca, 0.18-0.23% of Cu, 0.002-0.0035% of P, 0.28-0.295% of Al, 0.02-0.035% of Ti, 0.1-0.12% of Mo, 0.35-0.55% of Zn, 0.08-0.09% of Sn, 0.32-0.62% of Cr, 0.28-0.31% of Si, 0.8-1.2% of Ni, 0.25-0.33% of Mn, 0.01-0.015% of S, 0.51-0.62% of C and the balance of Fe. The components are combined to obtain the alloy steel through the combination function of a plurality of elements, and the comprehensive performance of the alloy steel is excellent; the produced alloy steel is applied to production of hardware, so that the processing property of hardware is greatly improved, and the application range of hardware is broadened.

Description

Technical field [0001] The invention relates to the production field of hardware equipment, in particular to a combined alloy steel suitable for manufacturing hardware parts. Background technique [0002] An iron-carbon alloy formed by adding an appropriate amount of one or more alloying elements on the basis of ordinary carbon steel. According to the different added elements, and adopting appropriate processing technology, special properties such as high strength, high toughness, wear resistance, corrosion resistance, low temperature resistance, high temperature resistance, and non-magnetic properties can be obtained. The main alloying elements of alloy steel are silicon, manganese, chromium, nickel, molybdenum, tungsten, vanadium, titanium, niobium, zirconium, cobalt, aluminum, copper, boron, rare earth and so on. Among them, vanadium, titanium, niobium, zirconium, etc. are strong carbide-forming elements in steel. As long as there is enough carbon, under appropriate condition...
