TOPIC: Resistance Heating Wire

Resistance Heating Wire 9 months 1 week ago #2716

Hi Venerable Scientists,

Is there any one who interested in production of resistance heating wire?
What is the process in order to manufacture resistance heating wire which is Resistohm-145 quality.

I wonder that Is it possible to produce by just wire drawing which cold?
Is the heating resistance wire shaped in a different way from cold drawing?

Thanks in advance.

Kanthal (Alloy 875/815), a ferromagnetic alloy, is a family of iron-chromium-aluminum (Fe-Cr-Al) alloys used in a wide range of resistance and high-temperature applications they are also used in the form of resistance wires.

Please see www.steelgrade.org/Steel-grades/High-all...stohm-alloy-145.html for mechanical properties and chemical composition. It is 70% iron, 24% chromium and 5.9% aluminum.

We suggest you discuss your drawing requirements with a well experienced manufacturer of ferrous wire drawing machinery to learn the details of the latest technology in drawing/ rolling Resistohm alloy 145 steel alloy.

Dear Mr.Stewart-Hay

Primarily, thank you for your interest.
- Is tempering necessarily required after cold rolling?
- Is bright annealing necessarily due to problems of oxidation?

Best Regards

Hello again,

I'm sorry but I am not an expert in the ferrous side of the wire and cable industry. The gentleman who moderates this Technical Division however is a true expert and hopefully he will be able to give you answers to your questions.

I initially replied because you erroneously left a copy of your message in the Electrical Division. Then I moved it over to the Ferrous Division.where it belongs.
