Chemical composition
In CIS countries medium-carbon alloyed steel of 40KhN2MA grade is produced in accordance with GOST 4543 specifications. The composition of steel includes the following elements:
| Element | Carbon | Silicon | Manganese | Chrome | Nickel | Molybdenum |
|---|---|---|---|---|---|---|
| Presence in steel, % | 0,37…0,44 | 0,17…0,37 | 0,50…0,80 | 0,60…0,90 | 1,25…1,65 | 0,15…0,25 |
As 40XHN2MA steel belongs to the steels of high quality, the percentage of metallurgical impurities — sulfur and phosphorus — is limited to 0,025%.
The best known foreign equivalents of 40XHN2MA steel are steel 34СrNiMo4 produced in Europe according to DIN 1.4731 norms and steel 36hnm produced according to Polish national standard. The chemical composition of 34CrNiMo4 is described below:
| Element | Carbon | Carbon | Carbon, silicon | Chrome | Nickel | Molybdenum |
|---|---|---|---|---|---|---|
| Presence in steel, % | 0,32…0,40 | Not more than 0.40 | 0,50…0,80 | 0,90…1,20 | 0,90…1,20 | 0,15…0,30 |
The percentage of impurities, such as sulfur and phosphorus, in 34CrNiMo4 steel should not exceed 0,035%.
Company Evek GmbH offers to buy pipes, bars, rounds of structural alloy steels 40KhN2MA, 34CrNiMo4 and 36hnm. The products are sold at economical producer price. Supplier provides timely delivery of products to the location specified by the customer.
Properties and application
Rolled tubes and pipes from chrome-nickel-molybdenum structural steel grades 40KhN2MA, 34CrNiMo4, 36hnm are used as forgings for further production of mechanical transmission parts (gears, shafts, gears, etc.), which are operated under high contact loads. Steels are well suited for all types of hardening heat treatments. Welding is possible by heating the products. Machining should be performed with carbide cutting tools.
Mechanical properties of steels after quenching and tempering:
- Tensile strength, MPa — 1100;
- yield strength, MPa — 950;
- Relative elongation, % — 12;
- Relative narrowing, % — 50…55;
- Impact toughness, kJ/m2 — 800… 1000.
Buy pipe, rod, rounds of alloy constructional steel 40XH2MA, 34CrNiMo4 and 36hnm at favorable prices from the manufacturer offers the company Evek GmbH. The supplier guarantees compliance with the assortment of rolled steel supplies, as well as prompt delivery of products to the location specified by the customer.
