Help looking for solid info. 1

[DJKeng]

Where can i find published minimum yield and tensile for
A513 Tube
A569 HR Sheet

I'm having a hard time finding consistant values. Please keep in mind i'm looking for minimum i.e. lowest grade.

Please site your source and intenet link if possible.

thanks so much

These are ASTM grades. Try Matweb as a start.

MatWeb doesn't help much with these specifications. Both include multiple alloys in various conditions, so Grades, Classes, Types, etc. need to be specified.

ASTM A513-07, 'Standard Specification for Electric-Resistance-Welded Carbon and Alloy Steel Mechanical Tubing' gives a wide range of alloys from 1008 to 8630 in a number of conditions (as-welded from hot rolled stock, as-welded from cold-rolled, mandrel drawn, etc.).

Strength requirements are supplemental in this spec. (negotiable when ordering). Table S5.1 gives minimums for round tubing in various conditions: normalized, stress relieved, mandrel-drawn, etc. The lowest minimum strengths are for normalized 1008 steel:
YS 23 ksi (159 Mpa), UTS 38 ksi (262 Mpa), elongation 30%.
Values go as high as UTS 110 ksi for mandrel-drawn 4140.

ASTM A569/A569M-98 Standard Specification for Steel, Carbon (0.15 Maximum, Percent), Hot-Rolled Sheet and Strip Commercial (Withdrawn 2000), replaced by
ASTM A1011/A1011M-06b Standard Specification for Steel, Sheet and Strip, Hot-Rolled, Carbon, Structural, High-Strength Low-Alloy, High-Strength Low-Alloy with Improved Formability, and Ultra-High Strength

http://www.astm.org/cgi-bin/SoftCar...A1011A1011M.htm?L+mystore+faub2290+1188434924

The lowest minimum strengths in A1011/A1011M (from 2002 version, possibly 2006 differs) are:
Hot-rolled low carbon steels:
CS Types A, B & C: YS 30-50 ksi (205-340 Mpa], elongation >25%, and
DS Types A & B: YS 30-45 ksi (205-310 Mpa), elongation >28%.

For SS (structural steel), the lowest strength is
Grade 30 [205]: YS 30 ksi (205 MPa), UTS 49 ksi (340 MPa), elongation 19.0-25.0% depending upon thickness.
HSLA grades have higher strengths.
Note: tensile properties are typical for CS & DS, mandatory for SS & HSLAs.
