General characteristics

Pipe HN77TYUR of corrosion-resistant special steel is classified as stainless steel pipes. It is intended to produce parts which are operated at high temperature (not higher 850ºС) in aggressive chemical environments. Due to the high content of Nickel, chromium, mechanisms and parts made from this alloy have high corrosion resistance, providing increased reliability of the equipment. Due to its cold resistance and the ability to hardening, brand HN77TYUR used in the manufacture of pipes of the suction type large thickness. However, despite its corrosion resistance, these pipes still unstable in the atmosphere of sulfur compounds and sulfur. Because of the content in the composition of the alloy of Nickel and titanium tubes are more expensive but are more reliable. Their cost kompensiruet durability and strength of the material.

Quality brand HN77TYUR at t° 20°C:

— The ultimate short-term strength = 950 MPa;

— yield strength of 620 MPa.;

max. elongation at break — 20%;

— max. contraction is no higher than 15%;

— hardness after hardening Brinell — 255 — 321 MPa.

Mechanical properties at t°100°C:

the linear expansion coefficient of 12.67x10^-6/°C;

— density of 8.18 g/cm3;

— heat capacity of 13.9 W/(m·deg);

the resistivity of 1,247, Mhmm²/m.

Use

Due to its strength, high corrosion resistance and durability of the pipe Yarki HN77TYUR used in very harsh conditions in the form of containers for transportation of chemical active substances, This pipe is not always the end product. It is often used as a workpiece for punching, cutting, pressing in the manufacture of separators, bearings and other parts of rolling. Pipe brand HN77TYUR is also used in the manufacture of parts installations in the oil and gas industry, which operate at high temperatures (above 600°C), in metallurgy and mechanical engineering. The process of production of these tubes requires strict control of compliance with the international, domestic standards of quality and safety, which allows further without any restrictions to their use in construction, chemical, food industry, medical industry and mechanical engineering.
