SAE 1566 Material 1

[Dobe]

I would like to know what is the shearing strength and carbon content of SAE1566 material?

 

[WKTaylor]

Just-to-be sure...

1566 = UNS G15660?

NO calls for SAE 1566

Yes, he does mean G15660, he just doesn't know it.

Dobe, what is the material specification? All that 1566 tells us is composition and nothing else.

Print says: SAE J403 SAE 1020 THRU 1080 OR SAE 4130 THRU SAE 4145 OR SAE 1536 THRU SAE 1566
HARDNESS rB 84 MIN.

I am looking for a shear strength or carbon to calculate tonnage for punch press.

J403 is just a list of steel grades and chemistries.
Do you have any other final part specs that you are supposed to meet?
Are there any requirement on heat treat condition (annealed, normalized and tempered, and so on)?
Otherwise this could be a huge range in properties.

the only other note listed is a stress relieve at 454°C to 510°C for 2 hours min.

It is not the material, but the required hardness of 84 HRB minimum you have to use. That translates to an approximate minimum tensile strength of 81 ksi (from ASTM A370). Shear strength is approximately 75% of tensile strength for steels, so you are looking at an approximate minimum shear strength of 61 ksi.

Carbon is specified as 0.60 - 0.71.

Thank you for the info. I did find the certs from the steel manudavturing and it does say carbon at .7

 

[EdStainless]

But since there is no max hardness you could be dealing with material at 1.5 times that strength. You need to check the specifics of the material that you have.
