afnor nf a54-301 Threaded Bar, DIN 1.3981 Bright and Square Bars Suppliers

Nilo Alloy K Round Bar is a nickel iron cobalt controlled expansion alloy made up mostly nickel. [Company Name] is a leading manufacturer and supplier of these products in various dimensions, sizes and shapes. The material has 29% nickel, 17% cobalt, 53% iron, carbon, manganese, titanium, silicon, chromium, copper and molybdenum in the composition.

The ASTM F15 UNS K94610 Rod comes under different dimensions according to the DIN, ASTM, ASME, AISI and other international standards. The round bars can come in black, bright polished, rough turned, no.4 finished, matt finish and BA finish types. There are round bars, square bars, hex bars, rectangular bars, billets, ingots and forgings. The Kovar Hex bar is used for the high strength and corrosion resistance. The application of this material is mostly seen in metal to glass seal applications. The material is highly resistant to thermal shock.

Due to this reason the Nf A54-301 flat Bar is used with high power transmitting valves. The other applications include chemical processing applications, food processing applications, petrochemical applications, pollution control applications, pulp and paper applications and in oil refineries. The bars are available in cold drawn pulished and cold drawn centreless ground and polished types. Please feel free to contact us for more information on the different types of DIN 1.3981 Square bar products and others with the pricing.

Nilo alloy k Round bar Heat Treatment

Heat Treatment of Finished Parts
The Nilo alloys are usually supplied and used in the annealed condition (residual cold work distorts the coefficients of thermal expansion).
Annealing times may vary due to section thickness.
Oxidizing time and temperature to be selected depending on required oxide thickness.

850 – 1000
1560 – 1830
Air or water
To prepare for glass to metal sealing
900 – 1050
1650 – 1920
Air or water
If a metal oxide interface is required
(time and temperature depend on required oxide thickness)
