Evek GmbH offers to buy sheets, strips, wires, which are made of structural steel 30X, AISI 5130, 30h, with high chromium content. Supplier guarantees economically advantageous price of the manufacturer, provides timely delivery of products to the customer.

Chemical composition

Alloy structural steel 30X with high chromium content is produced in accordance with the standards of GOST 4543. The steel composition includes:

• Carbon - 0,24...0,32%;
• Silicon - 0.17...0.37%;
• Manganese - 0,50 ... 0,80%;
• Chrome - 0,80 ... 1,10%.

GOST allows the presence in steel such metallurgical impurities as phosphorus and sulfur, their percentage content may not exceed 0,035% for each of the components.

The best known foreign equivalents of steel 30X are steel AISI 5130, (produced according to US standard ASTM A322) and produced in Poland steel 30h, which is almost exactly the same composition as given above for steel 30X.

The chemical composition of AISI 5130 is as follows:

• Carbon - 0.28...0.33%;
• Silicon - 0,15...0,30%;
• Manganese - 0.70...0.90%;
• Chromium - 0.80...1.10%.

According to ASTM A322 standard, the maximum percentage of non-metallic impurities - sulfur and phosphorus impurities is: for sulfur - 0.04%, phosphorus - 0.035%.

Buy at producer price sheet, wire ribbon of alloy steels 30Х, AISI 5130, 30h offers the company Evek GmbH. Supplier guarantees a favorable price for the rolled steel from its manufacturer, provides prompt delivery of products to the address set by the consumer.

Properties and application

Steels of 30X, AISI 5130, 30h grades are characterized by high strength and satisfactory heat resistance, which lasts up to temperatures of 300...⁴⁰⁰⁰ С. Steels can be subjected to all kinds of heat treatment, but they are not recommended for welded structures. Cold forming is possible with medium and small degrees of deformation.

After normalization, the main physical and mechanical parameters of the steel grades under consideration are in the following limits:

• Tensile strength - 1400 MPa;
• yield strength - 800 MPa;
• Young's modulus - 190...210 GPa;
• Brinell hardness - 180...240 NV (lower values correspond to the wire).

Company Evek GmbH offers to buy at producer price rolled sheets (sheets, strips) and also wire of alloy steels of 30Х, AISI 5130, 30h grades with high chrome content. The supplier guarantees the performance of the assortment range of deliveries, timely transportation of products to the point set by the customer.
