|Designation GOST Latin||05X18AH6M2FL|
|By chemical elements||05Cr18NН6Mo2V|
05Х18АН6М2ФЛ steel is used: for the manufacture of the 1st, 2nd and 3rd groups casting parts of valves and actuators to it, not subjected to welding, surfacing and operating in aggressive environments at temperatures of the working medium from -100 to +300 °C without limitation of the rated working pressure.
Steel 05Х18АН6М2ФЛ is a substitute for steel 12H18N12M3TL corrosive environments of increased aggressiveness.

According to CT CKBA 014-2004, a carbon content of up to 0.10% is allowed in the absence of test requirements for resistance to intergranular corrosion. When steel is smelted in electric furnaces with acid lining, the mass fraction of silicon is allowed up to 2.00% in the absence of the requirements for resistance to intergranular corrosion. The calcium content is introduced by calculation and is not an obligatory delivery characteristic.
