Composition and properties
Steel 30KH3MF produced in Russia and CIS according to technical regulations, GOST 4543, along with the following composition:
|The percentage of steel||0,27 0,34…||0,17…0,37||0,30…0,60||2,30 2,70…||0,20…0,30||0,06…0,12|
Steel 30KH3MF as an analogue is the steel grade 31CrMoV9, and in the US — steel 1.8519. The chemical composition of these steels differs from the above, as evidenced by the following table:
|The percentage of steel||Not more than 0.30||Not more than 0.40||Not more than 0,50||Not greater than 2.50||0.20||Not more than 0.15|
European standards and EN standards steel grades DINна 1.8519 31CrMoV9 and do not apply.

Structural alloy steels 30KH3MF, 31CrMoV9, 1.8519 can be subjected to hot forging, which is performed at temperatures of 850…10500 C. These grades of steel do not have a high capacity for machining, so used cutting tools made of high speed steels. For the production of welded structures the data used to a limited extent, with the use of welding fluxes or under an inert gas. Flat products of steels used in the manufacture of tanks and vessels operating at elevated pressures, and wire produced by cold heading technology highly resistant fasteners.To buy a circle, a wire, a strip of alloyed steel grades 30KH3MF, 31CrMoV9, 1.8519 a supplier company Electrocentury-steel.
