11H11N2V2MF co-Tube circle
Steel 11H11N2V2MF-w (EI962-sh) — nickel-chromium alloy. It consists of about 11% chromium, 1.5−2% nickel, and tungsten, up to 1% molybdenum and vanadium, and 0.11% carbon, hundredths of a percent phosphorus and sulfur. This relates to a heat resistant grade high alloys which are used for the manufacture of parts operating in the unloaded state at high temperature 900−1000 degrees.

Mark 11H11N2V2MF co-relates to the austenitic-feritnomu class. This class, when compared to austenitic steels — has a high reliability, resistance to intergranular corrosion, as well as greater resistance to stress corrosion cracking in chloride environments, and alkalis. This steel has a limitation welding, ie. e. Welding is performed after heating t ° 100−120 ° C with a mandatory final heat treatment. The use of austenitic and ferritic steels depends on operating conditions. The former can for a long time to temperatures of about 600 degrees. They can be classified as heat-resistant steel. If the operation temperature readings exceeds 600 degrees, are used austenitic steel.

Pipes brand 11H11N2V2MF-w have a lower nickel content in comparison with similar products — this strengthens the material and increases its stability in an environment saturated with sulfur. If necessary 11H11N2V2MF br-stamp may be replaced by a similar, with reduced carbon percentage, to preserve the mechanical properties. This steel has a balanced performance for high-temperature strength and heat resistance, so is widely used.
Seamless pipes produce a seamless manner. When using the welding — welding prepared pipe type. Depending on the type of coating pipes can have a matte or polished (mirror) surface. Pipes vary in relation to the diameter of the wall thickness. With a thickness of about 0.3−6 mm Ø 5−250 mm pipes are called extra thin-walled. A thin-walled tube has a thickness of 0,6−20 mm and the same diameter. Thick-walled tube has a wall thickness of 1,6−24 mm and Ø 6−250 mm. Especially pipes made from thick-wall thickness 2.12 mm, Ø 6−70 mm.
