Heat-resistant, relaxation-resistant steel

The company Evek GmbH offers to buy heat-resistant relaxation-resistant steel. The price is from the manufacturer. You can buy this steel in any assortment, delivery of products is carried out by the supplier

Company Evek GmbH offers to buy heat-resistant relaxation-resistant steel in any assortment of profiles. The price is from the manufacturer. The supplier guarantees strict adherence to the assortment of rolled products with delivery of products to any location specified by the consumer.

Composition and properties

The group of specified steels includes several grades of high-alloyed medium-carbon steels. Carbon content in them ranges from 0.2 to 0.4%. Common for these materials is high content of chromium, molybdenum and vanadium, some steels contain tungsten, titanium and boron. The steels are not allowed to contain bound nitrogen, and minimization of nonmetallic inclusions is achieved by increased aluminum content used for complete deoxidation.

Heat-resistant relaxation-resistant steels are produced under specifications of enterprises, but some of them are included in the list of alloy steels, melting of which is made according to the specifications of GOST 4543.

The mechanical and metallographic properties of heat-resistant relaxation-resistant steels are characterized by:

  1. Increased scale resistance, preserving up to 800...9000 C.
  2. The presence of pearlite in the microstructure.
  3. Stability of indicators of surface hardness and strength up to temperatures not lower than 450...5000 С.
  4. Low value of thermal expansion coefficient.

Company Evek GmbH offers to buy at prices from the manufacturer of sheet and section products made of heat-resistant relaxation steels. Quality assortment and prompt delivery to the address specified by the customer is guaranteed.

Application

Steels of this group are used:

  • For the manufacture of parts of turbines and other thermal power plants;
  • In the manufacture of heat-resistant fasteners;
  • For parts of reactors for chemical plants, as well as the relevant connecting fittings:
  • In the manufacture of spring assemblies for power generation facilities;
  • In the manufacture of moving parts of mechanisms that operate at high operating temperatures.

Evek GmbH offers to buy heat-resistant heat-resistant relaxation-resistant steel plates and bars at the manufacturer's price. The supplier ensures strict adherence to delivery dates and compliance of the product range with the terms of the contract.
