The density and specific heat relaxation-resistant steel. Physical and mechanical properties.
Are you interested in the properties of heat-resistant and relaxation-resistant steels from the supplier — Electrovek-Steel? At us you will find only the checked up information on the given subject
The company Electrovek-steel offers to purchase at affordable prices manufacturers of heat-resistant and relaxation-resistant steels. The supplier provides guaranteed delivery of products to the address specified by the consumer.
Depending on the area of the particular application, the steel under consideration must meet the following conditions:
For heat-resistant steels — to function in a loaded condition at temperatures not higher than 600 ° C for a long time. These steels include carbonaceous, low-alloy and chromium steels of the ferritic class;
For heat-resistant steels — to work in a loaded condition at high temperatures for a certain time, while possessing sufficient heat resistance. These steels include austenitic grade steel with the presence of chromium, manganese, nickel and molybdenum in its composition.
For heat and relaxation-resistant (scale-resistant) steels — when operating in an unloaded or lightly loaded state at temperatures above 550 ° C, it is resistant to chemical destruction of the surface in chemically active gas media. Examples of such steels are martensitic chromium-silicon steels, chromium-nickel austenitic steels, and chromium and chromium-aluminum steels of the ferritic class.
Heat-resistant and relaxation-resistant steels can be produced by methods of plastic deformation (rolling, drawing, hot extrusion), as well as foundry technologies.
Buy in the range of heat-resistant and relaxation-resistant steels at a bargain price from the manufacturer offers the company Elektrovek-steel. The supplier guarantees the timely delivery of products to any point specified by the consumer.
Properties of heat-resistant and relaxation-resistant steels
GOST 5632−2014 states that the main requirements for these steels are:
The ability to withstand certain mechanical loads (both static and dynamic) with constant exposure to high temperatures, and with a certain type of loading;
Corrosion resistance of steels to the action of corrosive gas media and water vapors in gaseous media at operating temperatures;
- Sufficient technological plasticity at realization of various technologies of plastic deformation, including at temperatures exceeding 600… 700 ° С — for deformable steels, and high indicators of fluidity — for steels obtained by casting.
Company Electrovek steel offers to buy at economically advantageous prices rolled and castings, made of heat-resistant and relaxation-resistant steels of any brand. The supplier ensures timely delivery of products to any point set by the customer.
