Precision - Introduction of metal stamping parts raw materials commonly used

by:Fortuna     2021-02-02
Precision, professional design and manufacture of precision metal molds and metal stamping parts of ODM/OEM manufacturer. Selected high quality raw materials imported from Japan, from the source to ensure product safety, long service life. With the domestic and foreign well-known brands of raw materials manufacturers ( Such as, ore, Wieland, etc. ) , mould steel, Hitachi, big equivalent) And powder metallurgy factory establish good interactive relationship, to ensure the shrapnel terminal materials authentic, can provide its core is tasted stamping parts with quality assurance. A, stainless steel, 1) Stainless steel, stainless steel small knowledge is short for stainless acid-resistant steel, including stainless steel, acid steel two kinds. Steel is stainless steel for corrosion resistance in the air, and in the acid, alkali, salt and other corrosive medium and its solution can resist the corrosion of steel acid-resistant steel. According to the characteristic of this kind of steel is divided into austenite size, the austenitic grain size of iron, iron grain size and martensite size as five kinds of precipitation hardening. Austenite size: mainly for chromium and nickel alloy element, the second with titanium, niobium, molybdenum, nitrogen, manganese, etc. This kind of steel is heated without phase change, without ferromagnetic, high toughness, low brittle transition temperature, good corrosion resistance and high temperature strength. This kind of steel grade common are: 301, 304, 316, etc. For chromium ferritic steel: the main alloy element, its content is usually equal to more than 13%, do not contain nickel, some steel also add molybdenum, titanium, sulfur, etc. Heating is no phase change, can change by heating method. This kind of steel has good oxidation resistance of medium corrosion ability, has the good workability. Common steel grade are: 430, 409, etc. Markov shape steel, chromium is the main element, its content is more than 13%, the carbon content is higher, you have phase change heat treatment, heat treatment method can be used to strengthen. High hardenability steel quenching tempering in the state of use has high strength, hardness and wear resistance. Common steel grade are: 410, 420, 420, 420 j1, j2, etc. New section nickel stainless steel: belong to austenite stainless steel body, replace 18 - with manganese and nitrogen 8 parts nickel in steel, so as to get good mechanical properties and corrosion resistance, the room temperature strength than 18 8 stainless steel high, under 800 degrees has good oxidation resistance and strength of medium temperature. Common steel grade: 202 mn content: 7. 5% ~ 10. 00%, the nitrogen content is less than or equal to 0. Another type of nickel 25% stainless steel in the 17th - 7 increase of manganese content in the stainless steel is 5. 5 to 7. 5, nitrogen with the above, such as steel grade: 201, has magnetic after cold working. Precision, professional design and manufacture of precision metal molds and metal stamping parts of ODM/OEM manufacturer. Stamping processing metal stamping parts mainly used in: micro-motor, acoustic components, sensors, relays, connectors, diodes, such as IC shrapnel is tasted. Apply to: automobile electronic, new energy battery, medical electronics, intelligent household, consumer electronics and IC packaging and other industries. Precision contact: wish you a prosperous business, everything goes well, if you want to learn more dynamic, can scan the qr code, pay attention to the public. , is committed to precision stamping processing factory of the world's most professional electronic components
