Evek GmbH offers to buy at a price from the manufacturer rolled sheets - sheets, strips and wires, which are made of structural chromium-nickel steel 20XH3A, 20hn3a and AISI 4320. Delivery of rolled products is carried out as soon as possible, the delivery of purchased products is carried out directly to the customer.
Chemical composition
One of the most demanded grades of chromium-nickel constructional steel - 20KhN3A steel - is produced in the CIS countries according to technical norms and requirements
| Component | C | Si | Мn | Cr | Ni |
|---|---|---|---|---|---|
| Percentage content in steel | 0,17...0,24 | 0,17...0,37 | 0,30...0,60 | 0,60...0,90 | 2,75...3,15 |
GOST allows the presence of metallurgical impurities in steel such as phosphorus and sulfur. Their content in the finished product should not be higher than 0.025%.
A number of foreign analogues of 20XHN3A steel is known. In particular, steel grade 20hn3a is produced by Polish metallurgical companies, and by its composition fully corresponds to grade 20KhN3A. Also known is AISI 4320 steel, which is melted in the USA according to ASTM A569 standards. The composition of this steel is given below:
| Component | C | Si | Mn | Cr | Ni | Mo |
|---|---|---|---|---|---|---|
| Percentage content in steel | 0,17...0,22 | 0,15...0,30 | 0,45...0,65 | 0,40...0,60 | 1,65...2,00 | 0,20...0,30 |
ASTM A569 specifies that the phosphorus and sulfur content limits may not exceed 0.035% and 0.040%, respectively.
Company Evek GmbH offers to buy at producer price rolled sheets - sheets, strips and wires, which are made of chromium-nickel constructional steel of 20XN3A, 20hn3a and AISI 4320 grades. Supplier provides favorable price from the manufacturer, guaranteed adherence to the range of supply and prompt transport of products to the client.
Properties and application
Steels 20XHN3A, 20hn3a and AISI 4320 are well machinable by cutting and in all operations of cold forging. The steels are characterized by high strength, are well amenable to all heat treatment operations and are well welded. The steels are used to produce critical general machinery items such as flat levers, bodies of large tanks operating at high pressures, as well as high-strength fasteners.
After annealing, the steels are characterized by the following physical and mechanical properties:
- Tensile strength - 580 MPa;
- yield strength - 425 MPa;
- Young's modulus - 190...210 GPa;
- Relative elongation - 29%;
- Relative narrowing of cross-section - 58%;
- Brinell hardness - not above 165 NV.
