Inconel 718 / 2.4668 / KhN45MVTYuBR
Stainless steels such as Inconel 718 are unique in their kind. In addition to traditional nickel and chromium, they also contain niobium, as well as molybdenum, iron, titanium and aluminum.
These heat-resistant materials are designed for the operation of alloy-based products in the widest temperature range ( -250°С …+700°С). In the Inconel family of alloys, this grade is considered the most popular and widespread. For the first time, the material of this brand was introduced back in the early 60s of the last century in the USA.
Features and application
Inconel stainless steel metal 718 is:
highest strength and rigidity;
ease of processing;
Possibility to create structures of the most complex shapes;
· protection of the welding zone from cracking.
Initially, the material was created for military purposes and was intended for the construction of supersonic aircraft (sheathing sheets). It has the highest tensile strength among analogues at temperatures below seven hundred degrees Celsius.
Nowadays it is used in the production of such equipment as:
Launch vehicle engines;
Also used for the needs of the gas, oil and chemical industries.
Main types rolled metal products – wire, sheets, strips, strips, pipes
