Evek GmbH offers to buy sheets and strips of low-carbon structural steel grades 18X2H4MA, X19NiCrMo4 and 1.6657. The supplier guarantees an attractive price from the manufacturer. Delivery of sheet metal products is carried out promptly, and to any point set by the consumer.

Chemical composition

Alloy steel of 18X2H4MA grade is produced in the CIS according to the requirements of GOST 4543. It features an increased percentage of molybdenum and nickel, which follows from the table below:

Component C Si Mn Cr Ni Mo
Percentage content 0,14...0,20 0.17...0,37 0,25...0,55 1,55...1,65 4,0...4,4 0,30...0,40

The presence of metallurgical impurities - sulfur and phosphorus is allowed in the steel, the percentage content of which is limited to 0.025...0.030%.

The European and North American analogues of 18Cr2Ni4MA steel are X19NiCrMo4 and 1.6657. They are produced in accordance with DIN 17210 (for Europe) and SAE-AISI 9310 (for the US) specifications. The composition of these steels is somewhat different from their domestic counterparts. For example, steel 1.6657 has the following chemical composition:

Component C Si Mn Cr Ni Mo
Percentage content 0,11...0,17 Up to 0.40 0,30...0,60 0,80...1,15 3,0...3,5 0,10...0,25

The presence of sulfur and phosphorus in an amount not exceeding 0.035% is omitted in the steels.

Buy rolled sheets of alloy constructional steel grades 18H2H4MA, X19NiCrMo4 and 1.6657 offers the company Evek GmbH. The products have an economically advantageous price of the manufacturer. Supplier provides compliance with the range of supply, as well as prompt transport of products to the point set by the customer.

Properties and application

Rolled sheets of the steels in question can be supplied in annealed and normalized condition. The physical and mechanical properties of 18X2H4MA, X19NiCrMo4 and 1.6657 steels are as follows:

  • Tensile strength - 820...910 MPa;
  • yield strength - 450...570 MPa;
  • Tensile strain - 17...19%;
  • Rockwell hardness - not above 240...270 HRB;
  • Impact toughness - not less than 120...130 MJ/m3.

18Cr2H4MA, Cr19NiCrMo4 and 1.6657 steels have increased values of their strength and impact toughness, and are therefore used in manufacture of critical steel structures and hull parts in shipbuilding, transport machine building, aircraft industry, etc. These steels are also used to manufacture pressure vessel bodies. Rolled sheets of 18X2H4MA, X19NiCrMo4 and 1.6657 are well processed by technology of plastic deformation.
