The company Evek GmbH offers to buy pipes, rounds, bars, which are made of medium-carbon alloy steel of 30ХГС and 30hgs grades, which contain a high percentage of chromium, manganese and silicon. The rolled steel is sold at the manufacturer’s price. The supplier also provides product delivery to the address specified by the customer.
Chemical composition
Grade 30 CGS steel is produced in accordance with GOST 4543 requirements, and has the following composition:
| Element | Carbon | Silicon | Manganese | Chrome | Nickel | Copper |
|---|---|---|---|---|---|---|
| Content in steel | 0,28…0,34 | 0,90…1,20 | 0,80…1,10 | 0,80…1,10 | Up to 0.30 | Up to 0.30 |
Sulfur and phosphorus metallurgical impurities are allowed in the composition of 30ChGS steel in the amount not exceeding 0.025%.
The foreign analogue of this steel is 30hgs steel produced in Poland. The chemical composition of the steel meets the requirements of the national standard and is given below:
| Element | Carbon | Silicon | Manganese, chromium | Titanium, vanadium | Nickel | Copper | Tungsten |
|---|---|---|---|---|---|---|---|
| Content in steel, % | 0,28…0,35 | 0,90…1,20 | 0,80…1,10 | Up to 0.05 | Up to 0.30 | Up to 0.25 | Up to 0.20 |
The standard allows for traces of molybdenum in 30hgs steel, and the maximum sulfur and phosphorus content may reach 0.035%.
Evek GmbH offers to buy circles, tubes and bars made of 30ХГС and 30hgs alloy constructional steels at producer price. The supplier provides the performance of the range of supply, guarantees prompt delivery of products to the consumer.
Properties and application
Alloy steels with high content of manganese, chromium and silicon are used for production of pipes for pipelines working under increased internal pressure, as well as for parts of machines and mechanisms, which are exposed to increased contact loads during operation. Steels are highly refinable and therefore they are also used for components such as pushers, rods, flanges and gears.
Physical and mechanical parameters of 30KhGS and 30hgs steels after quenching and tempering:
- Ultimate strength, MPa — 880…1100;
- yield strength, MPa — 600…750;
- Relative elongation, % — 13…15;
- Impact viscosity, kJ/m2 — 58…59;
- Brinell hardness, NV — 215… 240.
Buy at producer price rounds, pipes, bars of alloy construction steel 30ХГС and 30hgs offers the company Evek GmbH. Supplier guarantees adherence to the range of delivery, as well as prompt transportation of rolled products to the point specified by the consumer.
