Evek GmbH offers to buy pipes, rounds, bars made of 30X, AISI 5130, 30h alloy steels, containing high percentage of chromium. Supplier guarantees the price from the manufacturer, provides prompt delivery of rolled metal products to the location specified by the consumer.
Chemical composition
Chrome structural steel 30X is produced in the CIS countries in accordance with the technical requirements
- 0.24...0.32% of carbon;
- 0,17...0,37% of silicon;
- 0.50 ... 0.80% of manganese;
- 0.80...1.10% of chromium.
The presence of such non-metallic impurities as sulfur and phosphorus (in the amount of up to 0.035% for each of the elements) is allowed.
Some of the well-known foreign analogues of this steel are AISI 5130, which is produced in accordance with the US ASTM A322 standard, and 30h steel produced in Poland, the composition of which is practically identical to 30X steel.
The chemical composition of AISI 5130 is given below:
- 0.28...0.33% carbon;
- 0.15...0.30% silicon;
- 0.70...0.90% of manganese;
- 0.80...1.10% of chromium.
The limiting percentage of impurities is set by ASTM A322 standard at 0.04% for sulfur and 0.035% for phosphorus.
Company Evek GmbH offers to buy at producer price pipes, rounds and bars made of alloy steels of 30Х, AISI 5130, 30h grades. Supplier provides favorable price of products from its manufacturer, as well as timely delivery of rolled products to the address specified by the customer.
Properties and application
The steels under review are notable for high strength properties and ability to keep their working condition at elevated temperatures up to300-4000 C. They lend themselves well to all kinds of heat treatment and are notable for satisfactory weldability. Parts of gears, shafts, moving parts of power plants are made of these steels.
The main physical and mechanical properties of 30X, AISI 5130, 30h steels after normalization are as follows:
- Ultimate strength, MPa - 1400;
- Ultimate ductility, MPa - 800;
- Modulus of elasticity, GPa - 190...210;
- Brinell hardness, HB - 180 ... 240 (smaller values correspond to samples from bar stock).
Buy at a price from the manufacturer of the profile and bulk rolled metal - pipes, rounds, bars of alloy steel grades 30X, AISI 5130, 30h offers the company Evek GmbH. Supplier guarantees compliance with the range of supply, provides prompt delivery of products to the address specified by the customer.
