Alloy structural steel
Evek GmbH offers rolled alloyed structural steels in any range of sizes, diameters and thicknesses. Economically advantageous price from the manufacturer is valid. The supplier provides timely delivery of rolled steel to the address set by the consumer.
Features of chemical composition
Structural steel produced in CIS countries is produced under technical norms
Peculiarities of chemical composition of structural alloy steels are:
- Percentage of carbon, which may not exceed 0,6...0,75%;
- Mandatory presence of silicon (in the amount of 0,15...0,40%);
- Manganese whose percentage varies over a wide range - from 0.5% to 2% - and depends on the degree of alloying and the desired set of mechanical properties;
- Sufficient amount of alloying elements - not less than 0.05% - determining the performance characteristics of the steel.
Evek GmbH offers to buy a wide range of rolled alloyed structural steels at producer's price. Rolled sheets (sheets, strips, bands, coils), sections (channels, I-beams, angles, various special profiles), as well as rolled sections - bars, wires. Upon customer's request, delivery of forgings from steel of certain grades is possible, both from domestic and foreign producers.
Effect of alloying elements on mechanical properties of alloyed structural steels
Most often alloyed structural steels are composed of:
- Chromium - increases the wear resistance of steels under conditions of higher pressures and operating temperatures;
- Tungsten increases heat resistance of steels;
- Titanium - increases resistance of steels under conditions of constantly acting alternating loads;
- Molybdenum, Vanadium - these elements contribute to the active formation of carbides and nitrides in the microstructure, which increases the hardness of steel;
- Nickel - improves the machinability of steel by cutting and pressure;
- Boron - improves hardenability during heat treatment.
Evek GmbH offers to buy structural alloy steels at producer price. The supplier can provide supplies of plates, bars, volume production, as well as pipes, special profiles and forgings. Timeliness of delivery of a batch of rolled products to the customer is guaranteed.
