Heat-resistant steel A387 F5, Grade 5, Gr 5, 501, X12CrMo15, X11CrMo5, 12CrMo19-5, UNS S50200 for work at elevated temperatures for pressure applications, cracking, chromium-molybdenum according to EN 10216-2, EN 10222, ASTM A387, A182, A335, A213 etc.

A387 F5, Gr.5, Grade 5, 501, A182 F5, 1.7362, X12CrMo5 - Introduction and Application

Heat-resistant steel A387 F5, Grade 5, Gr 5, 501, X12CrMo15, X11CrMo5, 12CrMo19-5, UNS S50200 is an alloy chromium molybdenum pressure vessel steel plate designed for use in boilers, pressure vessels and heat exchangers at high temperatures. 

ASTM A387 Grade 5 is defined by the ASTM/ASME A387/A387M standard differs from the other grades covered by the standard in the chromium and molybdenum content of the steel.

Main use A387 Grade 5 in heat exchangers, boilers and pressure vessels and in a wide variety of ancillary uses such as pipes, flanges and fittings.

X12CrMo15 is a heat-resistant grade also classified as boiler steel for pressure applications and operation at elevated temperatures. It exhibits good strength properties at elevated temperatures and resistance to hydrogen under pressure.The grade is used for work with load and pressure up to 100 atm, at temperatures 450 - 600 ℃. It is mainly used in the form of pipes, sheets and hot-rolled bars in the production of oil cracking equipment in refineries, containing 0.75% Sulfur medium. Higher alloy grades with 7-9%. chromium content are selected for higher concentration of SulfurIn addition to the basic purpose, steel is also used in the manufacture of apparatus for hydrogenation of coal, ammonia synthesis equipment, superheaters and air heaters, parts of steam boilers, screws or bolts operating in aggressive conditions, turbine blades, pump parts, covers or springs of manometers.In the F5 or Grade 5 grade and replacements are delivered, among others: hot-rolled pipes, bars and sheets in annealed condition. The applied treatment is usually chosen due to the fine grain size of the structure. The delivery condition is also +NT1 and +NT2 (+QT). In addition to pipes, hot-rolled sheets and bars are also produced. The welding process requires preheating heating and maintaining the temperature of the welded place, and after welding the re-annealing.
