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
The present invention relates to valve part technical field, especially a kind of high strength spool.
Background technology
Valve utilizes a movable part carry out open and close or partly block one or more openings or passage, makes liquid stream, airflow or other air-flows or a large amount of bulk material can flow out, block or adjusted a kind of device; Wherein used spool is part very main in valve body.Existing spool generally based on bronze or stainless steel, also has plastics, nylon, pottery, glass etc., wears no resistance, easily cause valve disabler.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of high strength spool, become to be grouped into rationally, intensity is high.
In order to realize foregoing invention object, the invention provides following technical scheme: a kind of high strength spool, comprises the elemental composition of following weight percentage: carbon 0.2-0.4, silicon 0.1-0.2, titanium 1.2-1.5, boron 0.1-0.2, manganese 2.2-2.5, zinc 0.12-0.15, antimony 0.06-0.08, bismuth 0.09-0.12, ytterbium 0.03-0.05, chromium 4.2-4.5, molybdenum 0.4-0.6, indium 0.02-0.05, arsenic 0.3-0.5, hafnium 0.08-0.12, phosphorus 0.01-0.02, sulphur 0.01-0.025, surplus are iron.
Further, the weight percentage of each elemental composition is as follows: carbon 0.3, silicon 0.13, titanium 1.4, boron 0.12, manganese 2.25, zinc 0.13, antimony 0.07, bismuth 0.1, ytterbium 0.04, chromium 4.3, molybdenum 0.5, indium 0.03, arsenic 0.4, hafnium 0.09, phosphorus 0.01-0.02, sulphur 0.015, surplus are iron.
Compared with prior art, the present invention has the following advantages: by adding manganese and antimony element in ferro element, and by Bononizing pretreatment, improves intensity and the wear resisting property of spool, improve the work-ing life of spool.
