The company Electrocentury-steel offers to buy bulk rolling — circle, bar and forgings made of low carbon alloy steels 18KH2N4MA, Х19NiCrMo4 and 1.6657. The provider guarantees cost-effective price from the manufacturer. Delivery of products vypolnyaetsya at any point, which is defined by the customer.
Structural steel 18KH2N4MA is characterized by a high content of molybdenum and Nickel. It is produced in Russia and CIS according to GOST 4543, and has the following chemical composition:
|The content in steel, %||0,14…0,20||0.17 0,37…||Of 0.25 to 0.55||1,55 1,65…||4,0…4,4||Of 0.30…0,40|
The number of non-metallic impurities in the steel of sulfur and phosphorus — limited of 0.025…0,030%.
The closest European analogues of this steel are brand Х19NiCrMo4 and 1.6657, which are produced in accordance with the technical requirements of SAE-AISI 9310 and DIN 17210. The composition of these steels is somewhat different from 18KH2N4MA. For example, for steel 1.6657 he following:
|The content in steel, %||0,11 0,17…||To 0.40||0,30…0,60||0,80 1,15…||3,0…3,5||0,10…0,25|
Limiting the sulfur and phosphorous content is limited to 0,035%.
The company Electrocentury-steel offers to buy the bar, round, forgings of alloyed structural steels 18KH2N4MA, Х19NiCrMo4 and 1.6657. Price from the manufacturer. The supplier guarantees the compliance of the supply range and prompt transportation of goods to the point specified by the user.
Properties and applications
Forgings of the considered steel grades can be supplied in the annealed or normalized conditions. Initial physical-mechanical characteristics of materials are the following:
- Tensile strength, MPa 820 910…;
- The plastic limit, MPa — 450…570;
- Elongation % — 17…19;
- Rockwell hardness, HRB — 240…270;
- Impact strength, MJ/m3 — 120…130.
As a result of increased strength and toughness data of steel used in the manufacture of hull parts of ships, vehicles, aerospace, Railways, vessels, working under pressure, etc. of Steel 18KH2N4MA, Х19NiCrMo4 and 1.6657 are well-suited for hot volumetric stamping.
The company Electrocentury-steel offers to buy the bar, round, forgings of alloyed structural steels 18KH2N4MA, Х19NiCrMo4 and 1.6657. The price is from the manufacturer. The supplier provides the required product minimum and will deliver products to any place specified by the client.
