AISI 501 | EN 1.7362 | DIN X11CrMo5 15Х5М - martensitic «*stainless steel grade» is resistant to corrosion, provides heat resistance and good mechanical properties at high temperatures. Magnetic in any condition. Almost always annealed when used.
AISI 501 | EN 1.7362 is a heat-resistant grade, which is also classified as boiler steel. It is suitable for work under pressure and at elevated temperatures. It has good strength properties at elevated temperatures and resistance to hydrogen under pressure. It is used to work with a load and pressure of up to 100 atm, at a temperature of 450 ℃ - 600 ℃.
It is mainly used in the form of pipes, sheets and hot rolled rods in the production of equipment for cracking crude oil in oil refineries containing 0.75% sulfur medium.
Variants (analogues) of the grade with 7-9% chromium content are selected for use at higher sulfur concentrations. In addition to its main purpose, the steel is also used in the manufacture of coal hydrogenation apparatus, ammonia synthesis equipment, superheaters and air heaters, steam boiler parts, screws or bolts operating in aggressive conditions, turbine blades, pump parts, manometer covers or springs.
