1.7362, A194 Grade 3, Type 501, UNS S50100
1.7362, X12CrMo5 is a heat-resistant grade also classified as Boiler Steel(ASTM A387/A387M, SA387, Gr.5, Grade 5, F5) 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.
1.7362 grade and replacements are delivered, among others: Hot-Rolled pipe, bars and F5 sheets or Coils in Annealed condition.
Delivery condition: +NT1, +NT2, +QT.
