Property range for tensile and 1026.

Property range for tensile and 1026.

Property range for tensile and 1026.

(OP)
Alot of sources are reporting just a minimum range for the tensile strength of 1026. Do you know any source to find a suggested range for tensile and yield, instead of just a minimum.

I have searched alot of sources, including Mil handbook and Metals Handbook. They all appear to report the minimum tensile of 1026 and not a range.

RE: Property range for tensile and 1026.

As you already know, strength depends on thermomechanical processing, chemistry, etc.  Some additional data to the minimums that you already have:

Hot-rolled wire from electric arc furnace
two cooling rates-- fast & slow

Fast - yield = 43 ksi (295 MPa), tensile = 74 ksi (510 MPa), elongation = 30%

Slow - yield = 45 ksi (310 MPa), tensile = 80 ksi (550 MPa), elongation = 25%

This data is from a U.S. domestic steel mill, listed as typical.  Most 1026 is used for tubing or bars, this data may not be of much value if you require properties for cold-drawn bars.

RE: Property range for tensile and 1026.

dont have 1026 in my Guide to Engineered Materials.... (AMP December 2001)

But I do have 1022 and 1030:

           SAE 1022:         SAE 1030:
As Rolled (hot rolled):
UTS:          73ksi             80ksi
Yeild:        52ksi             50ksi
Elong:        35%               32%
Area Reduc:   67%               57%
Brinnel Hard: 149               179
Izod Impact:  60ft*lbf          55ft*lbf

Normalized at 1700F:
UTS:          70ksi             76ksi
Yeild:        52ksi             50ksi
Elong:        34%               32%
Area Reduc:   68%               61%
Brinnel Hard: 143               149
Izod Impact:  87ft*lbf          69ft*lbf

Annealed at 1600F:
UTS:          65ksi             67ksi
Yeild:        46ksi             50ksi
Elong:        35%               31.2%
Area Reduc:   64%               58%
Brinnel Hard: 137               126
Izod Impact:  89ft*lbf          51ft*lbf


I think that several of the values above are wrong:
yeild for 1030 all coditions. (shouldn't this be higher than 1022?)
Izod Impact for 130 annealed condition. (shouldnt the impact energy absortion increase for annealed steel?)

Hope this Helps!

I love materials science!
