Toughness improvement of high carbon tungsten steel 1.2562

[Larrin]

A while back I reported on the toughness of a range of low alloy steels typically used by forging bladesmiths. Among those was 1.2562, a steel with about 1.45% carbon and 3% tungsten making it the highest wear resistance low alloy steel. Unfortunately, this steel had relatively low toughness because of the high carbon content. Knifemaker Marco Guldimann said he wanted to show that the toughness could be improved through specialized processing. Here are the results of that testing. https://knifesteelnerds.com/2020/05/18/toughness-improvement-of-high-carbon-tungsten-steel-1-2562/

Thank you Larrin, and Marco for all the work and presenting the paper.

Very interesting thank you larrin and marco

Not a steel I use, but this is all very interesting.

As a future article, is it possible to look at hamon processes and activity? I’m quite curious as to why 26c3 is so resistant to the initial etch, more so than W2, W1, Hitachi Blue, Hitachi White, and 1095. I’m not sure what is going on with the chemistry to make it so etch resistant.

That’s a good question. I don’t know if I’m the right person to write about hamons because so much of it is logistical and “how-to.” I’ve never even done one before. The metallurgy sides of it I can write about of course.

I’ll touch base with you next week and see if there are any experiments we can do. I have a strangely busy week this week.
