Sheet, strip alloy 1.4923
Supplier — AvekGlob company — offers at reasonable prices from the manufacturer sheet and tape, which are made of steel grade 1.4923. A timely delivery of metal products to any address specified by the customer is guaranteed.
Steel grade 1.4923 belongs to the group of high-strength medium-carbon stainless steels of martensitic class, alloyed with chromium, vanadium and molybdenum. Steel is characterized by increased long-term creep resistance, including at elevated temperatures (up to 600… 650 0 С). A characteristic feature of the steel under consideration is high corrosion resistance in a vapor atmosphere. Cryogenic resistance of steel 1.4923 is relatively small, and does not exceed −10… −20 0 С.
Urgency of application
Products made from 1.4923 stainless steel are used in the manufacture of flue gas smoke pipes in an urban atmosphere that does not contain a high percentage of chlorides or vapors of hydrochloric acid salts. The steel in question is also used in production plants, power generating units of thermal power plants, as well as for corrosion-resistant assemblies of various industrial equipment: boilers, steam turbine blades and some aerospace parts that are not operated in chemically aggressive environments.
In accordance with the technical requirements of DIN EN 10302−2008, stainless steel 1.4923 includes the following components (numerical data — in percentages):
|0.18 — 0.24||Not more than 0.5||0.4 — 0.9||0.3 — 0.8||Not more than 0.025||Not more than 0.015||11 — 12.5||0.8 — 1.2||0.25 — 0.35|

Areas of application, technological features and assortment
Stainless steel 1.4923 is available in a variety of rolling profiles, as well as in forgings.
Steel is hardened during heat treatment. When complex shaping of sheet and bulk blanks in the cold state after deformation, annealing is necessary. Weldability of steel is satisfactory, the recommended technologies are manual electric welding by the WIG method or in an atmosphere of protective inert gases.
