Steel pipe brand 45KH14N14V2M (ЭИ69) is made of heat-resistant complex alloyed chromium-Nickel alloy. In its composition according to GOST 5632−72 from 13 to 15% chromium and Nickel. The average content of these elements is reflected in the alphanumeric designation of the steel — Х14Н14… the Number 45 represents the average carbon content in hundredths of a percent: 0,40 — 0,5%. 2−2 in the alloy, 8% tungsten, up to 0.4% Mo, 0.7% Mn, 0.8% Si, as well as sulfur and phosphorus, respectively, and 0.02 and 0.035%. The balance is iron. To the initial charge added elements that dramatically affect the quality of the finished product. This steel get in an open induction furnace method of electroslag remelting when the conductive slag electric current. This technique significantly increases the quality of the metal. The temperature of forging semi-finished products of about 1160 °C initially and about 850 °C at the end of the process. Alloy quenched in air or in water at temperatures up to 1100 — 1200 °C.
Percentage composition GOST 5632−72
This alloy is heat-resistant and heat-resistant but fragile in an environment containing sulfur. Pipe of this alloy is designed for continuous operation at t° 650 °C, but able to withstand a temperature increase to 850 °C, above which begins the formation of scale. Weldability is limited, the necessary pre-heating the parts up to 200 °C and a final heat treatment.
Such steel is used for the production of parts afterburner — an additional combustion chamber in the turbojet engine, increasing the thrust (she works at a temperature of 600−700°C and minimum load), for various mechanisms and parts of the pipeline systems, which also imposed a minimum load. In addition, for the manufacture of heating elements and welding wire for welding details, welding of metal structures in mechanical engineering. Pipe from this steel is used for vodootvedeniya, and also for removal of hot industrial gases. When heated, chromium and Nickel are active in forming the surface oxide film which increases the material resistance to aggressive environments. Circle and bars of this steel used as a template for products structural shapes: angle, beams, profile special purpose channel, which are used when performing construction works of any complexity. In the engineering industry circles are used for the production of tappets, axles, shafts.
