Material hardness in raw state

[Brian AbbottParticipant @brianabbott67793]

Hi all.

A little off topic but does anyone know a material which in its raw supplied state is around the 52 – 54 Rc mark ?

Thanks in advance.

Plenty of carbon, alloy and stainless steels can meet the requirement after hardening and tempering, but I'm not aware of any sold in a prehardened state. Those that are, like EN16T and EN24T aren't hard enough. There may be some ceramics that meet the requirements, but I haven't looked.

What form do you need the material in? Piano wire is only just below that and easily available in small diameters.

[HOWARDTParticipant @howardt]

Any flame hardening steel will achieve this to some depth, or do you require a through hardened steel. In which case look at the tool steels used for mould making. If its commercial Carrs Steel over Birmingham way are very good at giving you a good selection so long as you can furnish them with correct answers to the questions.

Thanks guys for taking the time to repy.

It was something for work, i needed some 25mm thick plate, customer calls for it to be hardened to 52-54, just had something in the back of my mind that there was something available, otherwise i need to heat treat which risks bending the plates.

Not to worry, thanks anyway..

… Just curious, Brian … Was my reference to 420 irrelevant to your requirement ?

Hi Brian what is it for and what sizes do you need. I have a few different steels

CMS 420 x 35mm dia. P20 x25mm dia. And D2 x 20mm dia.

If any are suitable let me know.

Seems pretty clear to me?

I have used TOOLOX 33 and 44, if I remember rightly that came in at around 420, was used for swaging dies in presses.

In the US we have AR500. It is an abrasion resisting plate with a Brinell hardness around 500. Nasty stuff to machine.
