Sheet, strip alloy 1.4922

Sheet, strip alloy 1.4922

Supplier — AvekGlob company — offers at reasonable prices from the manufacturer sheet and tape, which are made of steel grade 1.4922. A timely delivery of metal products to any address specified by the customer is guaranteed.

Technical specifications

Steel grade 1.4922 belongs to the group of high-strength medium-carbon stainless steels of martensitic class, which, in addition to chromium, are also alloyed with molybdenum. Due to the relatively low percentage of chromium, the corrosion resistance of this steel is limited. At the same time, this steel is highly corrosive in a vapor atmosphere, which remains at a temperature of 800 0 C and operates in the region of moderately negative temperatures.

Urgency of application

Products made from 1.4922 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 certain aerospace parts.

Chemical composition

In accordance with the technical requirements of DIN EN 10088, 1.4922 stainless steel includes the following components (numerical data — in percentages):

Element Minimal content Maximum Content
C 0.17 0.23

Areas of application, technological features and assortment

Stainless steel 1.4922 is available in a variety of rolling profiles, as well as in forgings.

Steel is hardened during heat treatment. When complex shaping of sheet blanks in the cold state after deformation, annealing is advisable. Weldability of steel is satisfactory, the recommended technologies are manual electric welding by the WIG method or in an atmosphere of protective inert gases.

Supplier — AvekGlob Company — offers to purchase a pipe, wire or a circle made of stainless steel 1.4922 at a price formed on the basis of European and world standards of production. Buy these products can be wholesale and retail. For regular customers, there is a flexible system of discounts.
