The company Electrocentury-steel offers economical price manufacturer of tubular and profile rolling of high-temperature, relaxation resistant steel 35KHM, 34СгМо4, 1.7230, AISI 4135. The provider provides the implementation of the range of supply and delivery of production to any point specified by the user.
Composition
Structural alloy steel 35 UM with a high content of molybdenum and chromium in Russia and CIS countries is made according to technical requirements GOST 4543. The chemical composition was the following:
| Component | Carbon | Manganese | Silicon | Nickel | Chrome | Molybdenum | Copper |
|---|---|---|---|---|---|---|---|
| The content in steel, % | 0,32 0,40… | 0,40…0,70 | 0,17…0,37 | To 0.30 | 0,80 1,10… | 0,15…0,25 | To 0.30 |
The composition of the steel, the slight content of metallurgical impurities — sulfur and phosphorus. Their percentage may not exceed 0,035% for each element.
Well-known foreign analogues of this steel. In the European Union is — steel 34СгМо4 (according EN standards), and steel 1.7230 (produced according to German DIN standard). In North America analog steel 35 HMM is steel AISI 4135. Their composition differs slightly from that given above. For example, steel 34СгМо4 includes:
| Component | Carbon | Manganese | Silicon | Nickel | Chrome | Molybdenum |
|---|---|---|---|---|---|---|
| The content in steel, % | 0,33 0,38… | 0,70…0,90 | 0,15…0,35 | To 0.30 | 0,80 1,10… | 0,15…0,25 |
Several high — to 0.040% is the permissible content of phosphorus.
The company Electrocentury-steel offers to buy rod, circle, pipe of medium carbon alloy steel grades 35KHM, 34СгМо4, 1.7230, AISI 4135. The vendor guarantees the price from the manufacturer, as well as prompt delivery of the products at the address specified by the customer.
Properties and applications
Physico-mechanical characteristics of the materials meet the following values:
- The modulus of elasticity of 190…210 GPA;
- Ultimate strength — 1400 MPa;
- The plastic limit is 800 MPa;
- Hardness Brinell (annealed and cold drawn steel) — 187…229 NV;
- Thermal conductivity: 42.7 W/MK.
Steel has a reduced ability to machining in cold condition, however, lends itself well to hot forging and stamping. Increased heat resistance to determine the manufacturer of the materials of forgings, gears, gear wheels, rods flanges, valves, steam lines, which are operated with higher loads, and at temperatures of up to 480…5100 C.
To buy a round, pipe, rod of heat-resistant relaxation resistant steel, the company offers Electrocentury-steel. The price is from the manufacturer. The supplier provides timely delivery of the products to the address specified by the consumer.
