Buy sheet and strip, made from structural alloy steels 20KH, 20Сг4, 20h, the company offers Electrocentury-steel. Supplier provided the best price from the manufacturer. Guaranteed prompt delivery of products to the address specified by the customer.
Low carbon alloy steel 20X, manufactured in Russia and the CIS countries in accordance with the technical requirements of GOST 4543, has the following composition:
|The percentage of steel||0,17…0,23||0,17…0,37||0,50…0,80||0,70 1,00…||Not more than 0.25||0.20|
Of non-metallic impurities in steel composition allowed the presence of phosphorus and sulfur, the percentage of which can not be more than 0,035%.
Steel 20KH has a number of foreign counterparts. For example, in Poland the steel with similar composition manufactured under the brand name 20h, and the countries of the European Union under the brand name 20Сг4. Technical requirements to the above listed steels correspond to the AISI 5120 standards and the European standards DIN 17210. The chemical composition of the analogues are almost identical Marche 20S.
To buy rolled metal sheet and strip obtained from structural steel stamps 20H, 20h 20Сг4 and doped with chromium, offers consumers a company Electrocentury-steel. Products are sold at cost-effective prices of the manufacturer. The supplier maintains the required minimum product mix and its operational delivery of products to the address set by the customer.
Properties and applications
Chromium alloy structural steel grades 20H, 20h 20Сг4 and can undergo various operations of heat treatment — annealing, vacation, hardening. After-school physical-mechanical characteristics of the considered steels are:
- The limit strength of 800 MPa;
- The yield strength is 650 MPa;
- Elongation — 11%;
- The relative narrowing of the cross section is not less than 40%;
- Brinell hardness number is no higher than 187 HB.
In most cases, pieces and parts from these steels provides for cementation. Cementation. After her rolled sheet is used to produce critical parts, the operation where the elevated contact stresses. Sheet and strip from the data of the steel lends itself well to the separation and formosanum operations cold forming (except for deep drawing), processed to metal cutting equipment. Weldability cemented products limited.
