Steel Grade

[pressbrake1]

Hello does anyone recognise this steel grade.
After four years my princess sister has given me access to my fathers workshop and there’s some steel there.
I had a piece checked by friendly scrap yard

If you add up the percentages, they do not reach 100. Does that mean the remaining is carbon? Do you know details of the machine used? That might give us access to the instruction manual which could tell us how to interpret the results on the screen.

The line at the top seems to be the machine's suggestion of grade.

The left hand one seems to be saying 8620 and finding an online spec. seems to be within the realms of possibility (https://www.astmsteel.com/product/aisi-8620-steel-alloy/) but if we assume that all the remaining is carbon, it is not within spec.

By the same logic, the right hand one looks like it is suggesting plain carbon steel.

Looking through some steel specs. (https://www.steeldata.info/hard/demo/html/carbon_steels.html), it is difficult to find anything with manganese that does not also have silicon in it. I do not know if that just means the machine cannot detect silicon or if looking around for steels that specifically do not have silicon but do have manganese would help.

I have tried to use one of these (quite expensive ) machines down at my local scrapyard and I think they just use them, all of them, to differentiate between "steel" "brass" "copper" "Ally" and the actual grade remains a mystery to them, but they don't care because that is the business they are in.

The local metal yard to us does know the machine as can tell the difference between stainless with them.
Boss bought alot of stainless (apparently 316) well it turned out to be mainly 309 with some 304 in there also.

All comes back to the operator using it.

Normal machines cannot detect carbon so we assume remainder is carbon so old en8 would read different to the modern ****e
It’s not a normal scrapyard , they deal in engineering materials
Guns are very accurate, the harder part is reading the data as it’s almost too sensitive
Common grades it will identify like en24 etc

Data means nothing if you don’t understand it!

Looking at the picture of the gun, I think it is a Thermo Scientific XL3t. Colour, button layout and the two rectangles above the screen match. It is difficult to be more specific (there is a 980 and an 800 on eBay).

What's the significance of knowing the gun?

Clive's after equivalent en spec for the steel

To determine what calibre of gunmetal it is. ….

As he said himself, "Data means nothing if you don’t understand it!". If we are able to interpret/understand the display on the machine, we know what spec. the machine thinks the material is. We can then look for the EN equivalent. It is hard to find an equivalent if you do not know to what you want it to be equivalent in the first place. I do not think you will find 'LEC' in any EN spec. as it is specific to the way the machine in question displays its results.

A Haynes manual for a Ford Escort might be some help in doing the tappets on a Vauxhall Cavalier, but a Vauxhall factory book of lies will be better.

Gun doesn’t matter
The composition is there, I only posted in case there’s a metallurgist lurking on here who can interpret the data into how the material will behave

Sadly TechnicAl does not lurk here anymore..

I've got his contact details if you need them.

I used the XRF gun at our scrap dealer (Bengleet Scrap) to identify some bronze. Turned out to be leaded gunmetal.

The 0.5Mn is a nice soft steel like they used to use for pipes. Just a low carbon/manganese steel.

This can be quite usefull to help id a material: https://www.matweb.com/search/CompositionSearch.aspx

I actually read what it was saying on the machine, it’s 8620

The one on the right is cooking mild steel - it's about what our PMI at work shows.

Shame my godmothers husband passed last year he was a true metallurgist and had been all his life so very little he didn't know. Great loss as he was very handy for odd questions.

Clive if you want to send me a small sample up I can put it through our indentation plastometer and give you a true stress and strain curve for the material
That along with the chemical analysis should narrow it down ?
