Composition

Steel brand KHN35VTJU (ЭИ787) is a high alloy high-temperature steel, which made parts designed for operation at temperatures up to 900−1000°C in a lightly loaded condition. This steel refers to partially welded, the welding is performed by heating to a temperature of 100−120°C with further heat treatment. Of about 1/3 of Nickel 14 — 16% chromium. Besides tungsten, titanium, aluminum, one percent silicon, a quarter of a percent of copper, hundredths parts of phosphorus and manganese.

The percentage composition of (GOST 5632−72)

Comparative characteristics

This steel belongs to ferrite-austenitic class. Compared to the austenitic type of steels they have better strength (almost twice), and high corrosion resistance intergranular type, as well as greater resistance to stress corrosion cracking in chloride and alkali environments. The application of ferritic and austenitic steels depends on the operating conditions. First able to withstand temperatures of about 600 °C. They can be classified as heat resistant steels. If the production reaches temperatures above 600 °C, austenitic steels are used. In accordance with GOST intensive education in the scale begins to occur at temperatures constituting approximately 1050 °C. Tube KHN35VTJU contain slightly less Nickel than other products from the same steel, resulting in increased strength of the material and increases its durability in a rich sulfur environment. Pipe brand KHN35VTJU can be changed to other, with a reduced amount of carbon without loss of strength advantages. This steel has a relatively balanced performance of heat resistance and heat resistance, so it is so popular.

Application

The use of reliable and durable pipes made of stainless steel saves time and money on maintenance and replacement of equipment. For example, there is no need in the color of the pipe or protective coating. The pipe can be made seamless — seamless type, and also by welding — welded tube. In accordance with the type poerhnosti pipe may be indicated in catalogues such as Matt, brushed, mirror, polished. Round KHN35VTJU can be used as forgings, ie intermediate preform for different products. Manufacturer of round steel of this brand is made by punching metal deformation under a predetermined shape.
