11KH11N2V2MF - эи962 sheet, round, wire
Steel 11KH11N2V2MF-sh (ЕИ962-W) — chrome-Nickel alloy. It consists of about 11% chromium, 1.5−2% of tungsten and Nickel, up to 1% molybdenum and vanadium as well as carbon 0.11 percent, hundredths of a percent of phosphorus and sulfur. This high-temperature grade applies to highly alloyed alloys, which are used to manufacture parts operating in an unloaded state at high temperatures 900−1000 degrees.
Percentage composition GOST 5632−72
Brand 11KH11N2V2MF-sh relates to austenitic-peritomy class. This class, when compared with austenitic steel has higher reliability and resistance to intergranular corrosion and greater resistance to stress corrosion cracking in alkaline and chloride environments. This steel has limitations for welding, i.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 the operating conditions. First can for long time to temperatures of about 600 degrees. They can be classified as heat resistant steel. If the operation temperature exceeds 600 degrees, the use of austenitic steel.

Pipe brand 11KH11N2V2MF-sh have a lower Nickel content compared to similar products — this strengthens the material and increases its stability in environments saturated with sulfur. If necessary, mark 11KH11N2V2MF-sh may be replaced by a similar, with a reduced percentage of carbon, to preserve the mechanical properties. This steel has a balanced performance of heat resistance and heat resistance, so is widely used.
Seamless pipes are produced in a seamless way. When using weld — receive tube, welding type. Depending on the type of coating a pipe can have a matte or polished (mirror) surface. The pipes vary in ratio of wall thickness to diameter. At a thickness of about 0.3−6 mm and Ø 5−250 mm pipe referred to as extremely thin-walled. Thin-walled tube has a thickness of 0,6−20 mm with the same diameter. Thick-walled pipe has a wall thickness of 1,6−24 mm and Ø 6−250 mm. Particularly thick-walled pipe is made with a wall thickness of 2−12 mm, Ø 6−70 mm.
