Bisalloy 360 Cleaver?

[steamingutpiles]

I've been doing a little tinkering & making long handled meat cleavers usining Bisalloy 360. The material is about 10mm in thickness and the cleavers are about 600mm (2ft) long. My questions are: 1. Is it necessary to harden/anneal this steel for practical purposes. 2. If it is what procedure do you recommend? Thank you in anticipation.

I dont think I have ever heard of Bisalloy until you just told about it. most of what I'm seeing is all low carbon, at only .32% for Bisplate500 (here's my source http://www.bisalloy.com.au/files/Techman/Range of Grades.pdf )

I could not find any metalurgy info for Bisalloy360 so if you could provide that that would be great.

This is a Aussie steel company.With that large a cleaver you must be chopping very large 'roos. These steels are hardened at the mill and it wouldn't be a good idea to reHT them.The numbers represent Brinell hardness
500 HB = 52 HRc
360 HB = 39 HRc
You could grind them as is, they're soft enough
