1.4944 - 286 alloy pipe, wire, circle

1.4944 - 286 alloy pipe, wire, circle

Supplier — AvekGlob Company — offers a pipe, wire and a round at a reasonable price from the manufacturer, which are made of steel 1.4944 (alloy A-286). It is guaranteed timely delivery of metal products to any address specified by the consumer /

Technical specifications

Steel grade 1.4944 (also called alloy A-286) belongs to the group of stainless steels alloyed with chromium and nickel. The steel is manufactured according to the North American standard AISI / SAE 660 and UNS specification S66286.

Steel 1.4944 (alloy A-286) is characterized by high corrosion resistance at elevated temperatures. In particular, for a short time products made from this steel can be used without the risk of surface damage at temperatures reaching 750 0 C (in dry air — up to 820 0 C). The strength of steel is significantly increased after its heat treatment. High values of the mechanical strength of steel are also preserved at cryogenic temperatures. Thus, stainless steel 1.4944 (alloy A-286) is a material whose operation is controlled solely by changing the duration and temperature of its heating.

Urgency of application

Products that are made of stainless steel 1.4944 (alloy A-286), are characterized by high strength and good corrosion resistance at high temperatures. Steel is well hardened by heat treatment, and therefore suitable for the production of high-temperature fasteners and other high-temperature static applications. Typical products are jet engines, chargers, chargers of increased durability, high-temperature burners for heating gas furnaces.

Chemical composition

In accordance with the technical requirements of ASTM A453, stainless steel 1.4944 (alloy A-286) includes the following elements:

  • Ni — 24… 27%
  • Cr — 13.5… 16%
  • Ti — 1.90… 2.30%
  • Fe — base
  • Al — no more than 0.35%
  • V is 0.10… 0.50%
  • Si — no more than 1%
  • C — not more than 0.8%

The composition of steel allowed the presence of boron (0.003… 0.01%), copper (no more than 0.5%), cobalt (not more than 1.0%) and lead (not more than 0.005%). The amount of metallurgical impurities — sulfur and phosphorus — should not exceed 0.015% and 0.02%, respectively.

Physical and mechanical properties:

Density, kg / m 3 — 7940;

The coefficient of thermal expansion in the temperature range of 20… 100 0 С, μm / degree — 16,4;

Coefficient of thermal conductivity, W / megade — 12,7;

Modulus of elasticity, GPa — 205;

The limit of temporary resistance, MPa — 930… 1180;

Yield strength, MPa — 635;

Relative narrowing of the cross-sectional area,% — 40 ;;

Relative elongation at a stretching,%, not less than — 12.

Areas of application, technological features and assortment

Stainless steel 1.4923 is available in a variety of rolling profiles, as well as in forgings. The main forms of supply are hot-rolled steel with annealing, cold rolling with annealing, drawing, rolling with polished rollers, forgings.

Supplier — AvekGlob Company — offers to buy a pipe, wire or a circle made of stainless steel 1.4944 (alloy A-286) 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.
