Composition and properties
In Russia and the CIS medium-alloyed structural steel 30KHM produced according to the norms of GOST 4543 and has the following chemical composition:
| Item | Carbon | Silicon | Manganese | Chrome | Molybdenum |
|---|---|---|---|---|---|
| The percentage | 0,26 0,34… | 0,17…0,37 | 0,40…0,70 | 0,80 1,10… | 0,15…0,25 |
GOST permits the presence of metallurgical impurities — phosphorous and sulfur, the number of which should not exceed the value of 0.025…0,030%.
The closest foreign analogues of this material — and steel 25CrMo4 1.7218. By composition they are slightly different from brand 30KHM:
| Item | Carbon | Silicon | Manganese | Chrome | Molybdenum |
|---|---|---|---|---|---|
| The percentage | 0,22 0,29… | To 0.40 | 0,60…0,90 | 0,90 1,20… | 0,15 0,30… |
In addition, European standards allowed the presence in these steels of copper (0.3%), Nickel (up to 0.4%) and aluminium (up to 0.04%).
The mechanical properties of the examined steels after annealing the following:
- Tensile strength, MPa — 950;
- The plastic limit, MPa — 750;
- Elongation, percent — 11;
- The relative narrowing, % — 50;
- Impact strength, kJ/m2 — 900.
The company Electrocentury-steel offers to buy a round, rod, pipe from steel 30KHM, and 25CrMo4 1.7218. The price is from the manufacturer. Supplier will deliver products to any destination specified by the customer.
Application
These steels respond well to all types of heat-treated and plastically formoizmeneniya with significant degrees of deformation. Therefore of them it is possible to produce quite complex three-dimensional parts such as shafts, flanges, sredneshirotnykh gears and gear wheels. Steels have good weldability, so a tubular rental of the described materials used for laying of pipelines.
The company Electrocentury-steel offers to buy the rolled medium-carbon alloy steels 30KHM, and 25CrMo4 1.7218 at factory price. The supplier provides timely and fast deliveries.
