Evek GmbH offers to buy bulk rolled metal products and forgings made of chromium structural steel grades 40Kh, 41Cr4 and 40h. The supplier guarantees the price from the manufacturer, as well as timely delivery of products to any location specified by the consumer.
Chemical composition
Medium-carbon structural steel of grade 40Kh is produced in accordance with the specifications
| Element | Carbon | Silicon | Manganese | Chrome | Nickel | Copper |
|---|---|---|---|---|---|---|
| Percentage content in steel, % | 0,36...0,44 | 0,17...0,37 | 0,50...0,80 | 0,80...1,10 | Up to 0.30 | Up to 0,25 |
The content of metallurgical impurities - phosphorus and sulfur - is limited to 0.035%.
The closest European counterparts of this steel are 41Cr4 (produced according to European Union standards EN 10262-4 for volumetric rolling and EN 10250-3 for forgings) and 40h steel (produced according to Polish standard PNH 84030). Their chemical composition practically does not differ from the above, except for nickel and copper at trace level.
Evek GmbH offers to buy circles, bars, forgings of chromium steel grades 40Kh, 41Cr4 and 40h. Supplier guarantees an economically attractive price from the manufacturer, and provides timely delivery of purchased products.
Properties
In delivery condition (after heat treatment) the steels under review have the following physical-mechanical properties:
- Tensile strength, MPa - 100;
- The limit of plasticity, MPa - 80;
- Relative elongation, % - 10;
- Impact toughness, kJ/m2 - 6.
Forgings, rounds and bars of chromium constructional steel grades 40Kh, 41Cr4 and 40h are used for the manufacture of shafts, axles, rods, gears, couplings, pins and laths of critical mechanisms that must have high surface hardness. Steels can be subjected to various types of heat treatment - hardening, normalization, tempering.
Evek GmbH offers to buy bars, rounds, forgings of quality structural steels with high chrome content. The price from the manufacturer. Supplier guarantees strict adherence to delivery terms and range of products required by the customer.
