[0013] A high-strength valve core, containing the following elemental components in weight percent: carbon 0.2, silicon 0.2, titanium 1.2, boron 0.2, manganese 2.2, zinc 0.15, antimony 0.06, bismuth 0.12, ytterbium 0.03, chromium 4.5, molybdenum 0.4, Indium 0.05, arsenic 0.3, hafnium 0.08, phosphorus 0.02, sulfur 0.01, and the balance is iron.
[0014] By adding manganese and antimony elements to the iron element, and through boronizing treatment, the strength and wear resistance of the valve core are improved, and the service life of the valve core is improved. The alloy steel of the invention is suitable for manufacturing the valve core, is corrosion-resistant, and obviously prolongs the service life of the valve body.

Abstract
The invention discloses a high-strength valve element. The high-strength valve element comprises the following element components in percentage by weight: 0.2-0.4% of carbon, 0.1-0.2% of silicon, 1.2-1.5% of titanium, 0.1-0.2% of boron, 2.2-2.5% of manganese, 0.12-0.15% of zinc, 0.06-0.08% of antimony, 0.09-0.12% of bismuth, 0.03-0.05% of ytterbium, 4.2-4.5% of chromium, 0.4-0.6% of molybdenum, 0.02-0.05% of indium, 0.3-0.5% of arsenic, 0.08-0.12% of hafnium, 0.01-0.02% of phosphor, 0.01-0.025% of sulfur, and the balance of iron. According to the high-strength valve element, the manganese element and the antimony element are added into the iron element, and boronizing treatment is carried out, thereby improving the strength and the wear resistance of the valve element, and prolonging the service life of the valve element.
Description
technical field [0001] The invention relates to the technical field of valve parts, in particular to a high-strength valve core. Background technique [0002] A valve is a device that uses a movable part to open, close or partially block one or more openings or passages, so that liquid flow, air flow or other air flow or a large amount of loose material can flow out, block or be regulated; The spool used is a very important part of the valve body. Existing spools are generally made of bronze or stainless steel, as well as plastics, nylon, ceramics, glass, etc., which have poor wear resistance and easily cause valve function failure. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention proposes a high-strength valve core with reasonable composition and high strength. [0004] In order to achieve the purpose of the above invention, the present invention provides the following technical solutions: a high-strength valve core, includin...
