Rolled metal strip, sheet — made of alloy steels 20KHGNM, 20NiCrMo2−2, AISI 8620 offers to buy at an economical price from the manufacturer company Electrocentury-steel. Supplier guarantees the purchase of sheet metal at factory price, and ensured prompt delivery of rolled metal to a point which is specified by the customer.
Alloyed with chromium, manganese, Nickel and molybdenum steel 20 HGNM produced in Russia and in the CIS States, respectively, of technical requirements GOST 4543. The chemical composition of steel is given in table:
|The percentage of steel||0,18 0,23…||0,17…0,37||0,7…1,1||0,4…0,7||0,4…0,7||0,15…0,25||Not more than 0.3|
Allowable non-metallic impurities in the composition of the steel contains phosphorus and sulfur (not more than 0,035%).
The closest foreign analogues of steel 20 HGRM are: for Europe — steel 20NiCrMo2−2 (1.6523 parallel marking), which is produced according to standards EN 10084, US — steel AISI 8620, the composition of which must conform to the standards of ASTM A29. The chemical composition of steel AISI 8620 is as follows:
|The percentage of steel||0,18 0,23…||0,15…0,35||0,70…0,90||0,40…0,70||0,40…0,60||Of 0.15…0.25|
In steels 20NiCrMo2−2 8620 and AISI it is possible to have non-metallic impurities — sulfur and phosphorus, limited the sulphur 0,035%, and phosphorus 0,040%.
The company Electrocentury-steel offers to buy the sheet and strip produced from an alloy structural steel grades 20KHGNM, 20NiCrMo2−2 and AISI 8620. Supplier provided the best price from the manufacturer, guaranteed timely delivery of sheet metal, at the address provided by the customer.
Properties and applications
Steel 20KHGNM, 20NiCrMo2−2, AISI can be subjected to effective heat treatment processes — normalization, tempering, vacation. In the initial state data has the following physical-mechanical characteristics:
- Limit strength is 530 MPa.
- Yield strength is 385 MPa.
- Young’s Modulus — 190…210 GPa;
- Elongation — 15% ;
- Toughness — 119 kJ/m3;
- Hardness on the Brinell hardness is not greater than 149 NV.
The machinability of alloyed structural steels 20KHGNM, 20NiCrMo2−2, AISI 8620 on machine tools — average, but good sheet metal is deformed and welded under flux. Of these steels manufacture components whose operation leads to significant alternating load.
Sheet and strip, made from alloyed steel grades 20KHGNM, 20NiCrMo2−2, AISI 8620 offers at factory price company Electrocentury-steel. Supplier ensure timely delivery of products to the address indicated by the consumer.
