Evek GmbH offers pipes, bars, circles made of medium-carbon steel grades 38ХА or 37Cr4 (1.7034), aisi 5135, containing a high percentage of chromium. The products are sold at the manufacturer's price. Supplier provides strict compliance with the assortment of rolled products supply, guarantees its timely delivery to the point specified by the customer.

Chemical composition

Alloyed structural steel of 38ХА grade is produced in the CIS countries according to the technical requirements of GOST 4543. The steel consists of the following elements:

• Carbon 0.35...0.42%;
• Silicon 0.17...0.37%;
• Manganese - 0.50...0.80%;
• Chrome - 0.80...1.10%.

As this steel belongs to the group of high quality steels, GOST limits the content of non-metallic impurities in 38ХА steel - sulfur and phosphorus: their quantity must not exceed 0.025%.

Foreign analogues of the steel in question - steel grade 37Cr4 (1.7034), which is produced in Europe in accordance with standards EN 10083-3, EN 10263-4 and EN 10250-3. The composition of the steel is given below:

• Carbon - 0.34...0.41%;
• Silicon - no more than 0.40%;
• Manganese - 0.60...0.90%;
• Chromium - 0.90...1.20%.

Phosphorus and sulfur limits for steel 37Cr4 (1.7034) are 0.045% and 0.035% respectively.

Company Evek GmbH offers to buy at producer price pipes, bars, rounds, which are made of steel 38ХА, aisi 5135 and 37Cr4 (1.7034). The economically advantageous price from the manufacturer. Supplier guarantees compliance with the range of supply of rolled products, guarantees its timely delivery to the address specified by the customer.

Quality and application

Forgings, bars and tubes made from 38ХА, aisi 5135 and 37Cr4 (1.7034) steels are used in production of mechanical system parts - shafts, gears, axles, bushings - which require an optimal combination of high surface hardness and tough core. Steels can be subjected to all types of hardening heat treatments and hot forging operations. Mechanical processing is effective with the use of carbide metal-cutting tools.

The main physical and mechanical characteristics of steels after quenching and tempering:

• Tensile strength, MPa - 1100;
• yield strength, MPa - 850;
• Relative elongation, % - 12;
• Relative narrowing of cross-section, % - 50;
• Brinell hardness, NV - not above 255.

Evek GmbH offers to buy structural rolled products - bars, rounds and tubes made of chromium-alloyed construction steel 38ХА, aisi 5135 and 37Cr4. The price is from the manufacturer. Supplier provides timely delivery of rolled products to the address, which is set by the consumer.
