Composition and properties

30Cr3MF steel is produced in CIS countries according to GOST 4543 technical specifications and is distinguished by the following composition:

Element	C	Si	Мp	Cr	Mo	V
Percentage content in 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 30CrMoV9 has as an analogue steel 31CrMoV9, and in the USA - steel 1.8519. The chemical composition of these steels differs from the above, which is confirmed by the following table:

Element	С	Si	Mn	Cr	Mo	V
Percentage steel content	Not more than 0.30	Not more than 0.40	Not more than 0.50	Not more than 2.50	Not more than 0.20	Not more than 0.15

The European EN and DIN standards do not apply to 31CrMoV9 and 1.8519 steel grades.

These steels are subjected to all heat treatment regimes. After softening annealing they have the following mechanical properties:

• Tensile strength - 1000 MPa ;
• Yield strength - 850 MPa;
• Relative elongation - 12%;
• Relative narrowing of the cross section - 50%;
• Impact toughness - 1000 ^kJ/m2;

Application

Structural alloy steels 30Cr3MF, 31CrMoV9, 1.8519 can be subjected to hot forging, which is carried out at temperatures of 850 ... ¹⁰⁵⁰⁰ C. The specified steel grades are not high capable of machining, so the metal-cutting tools made of high-speed steels are used. For production of welded structures these steels are used on a limited scale, using welding fluxes or under a layer of inert gas. Rolled sheet steel is used in the manufacture of tanks and vessels operating at high pressures, and the wire is made by cold heading technology highly resistant fasteners.

Buy rounds, wires, ribbons of alloy steels grades 30Kh3MF, 31CrMoV9, 1.8519 offers the supplier - company Evek GmbH. The price is from the manufacturer. Timely delivery of products to the location specified by the customer is provided
