To by pipe, rod, round, made of medium carbon steel grades 38KHA or 37Cr4 (1.7034), aisi 5135 containing a higher percentage of chrome, the company offers Electrocentury-steel. Products are sold at factory price. The provider ensures strict compliance of product mix and the supply of hire, ensures their timely delivery to the point specified by the customer.

Chemical composition

Alloy structural steel brand 38KHA produced in Russia and CIS countries, respectively the technical requirements of GOST 4543. In the composition of the steel includes the following elements:

• Carbon — 0,35…0,42%;
• Silicon — 0,17…0,37%;
• Manganese — 0,50…0,80%;
• Chrome…0,80 1,10%.

Because the steel is included into the group of high-quality steels, GOST restricts content in the steel 38KHA non-metallic impurities — sulfur and phosphorus: their number should not exceed 0,025%.

Foreign analogue of the considered steel — steel grade 37Cr4 (1.7034), the production in Europe is carried out according to standards EN 10083−3, EN 10263−4, EN 10250−3. The composition of steel is given below:

• Carbon — …0,34 0,41%;
• Silicon is not more than 0.40%;
• Manganese — 0,60…0,90%;
• Chrome is 0.90…1.20 percent.

Limit phosphorus and sulfur for steel 37Cr4 (1.7034) is respectively 0,045% and 0.035%.

The company Electrocentury-steel offers to buy at factory price tube, rod, round, which are made of steel 38KHA, aisi 5135 and 37Cr4 (1.7034). Operates a cost-effective price from the manufacturer. The supplier guarantees compliance with the range of supply of rental services guarantee its timely delivery to the address set by the customer.

Property and application

Forgings, rolled products and tubes produced from steels 38KHA, aisi 5135 and 37Cr4 (1.7034) are used in the manufacture of parts of mechanical systems — shafts, gears, axles, bushings — in operation which requires the optimum combination of high surface hardness and tough core. Steel can be subjected to all types of hardening heat treatment operations and hot forming. Mechanical treatment is effective with the use of carbide cutting tools.

Main physico-mechanical characteristics of steels after quenching and tempering:

• The limit of temporary resistance, MPa — 1100;
• Yield strength, MPa — 850;
• Elongation, % of 12;
• The relative narrowing of the cross section % — 50;
• Brinell hardness number, HB — not above 255.

To buy bulk rolled round bar, circle, and pipes made of stainless steel with chromium structural steel 38KHA, aisi 5135 and 37Cr4 the company offers Electrocentury-steel. The price is from the manufacturer. The supplier provides timely delivery of rent at the address set by the user.
