Borrowed this info from a post originally done by "choppersuey" on another Chop site.
All good info when thinking of using the "round stuff" for frame construction....
"Tube Type: ERW - Hot Rolled
Grade: C1010
Specification and Finish: ASTM A513 Type 1, As Welded, Hot Rolled
Description: Hot Rolled Electric-Resistance Welded (ERW) Carbon Steel Mechanical Tubing Good forming quality tubing. A513 Type 1 can be purchased with ID weld flash-in, flash controlled, or flash removed. Available in surface finishes of hot rolled or hot rolled pickled and oiled.
Typical Applications: Automotive and truck components, frames, racks, railings, roller sleeves and industrial machinery.
Typical Mechanical Properties:
Tensile Stregth: 45,000 PSI
Yeild: 32,000 PSI
Elongation: 15% min.
Hardness: 55 Rockwell B
Fabrication Characteristics:
Weld-Ability: Good
Machine-Ability: Good
Tube Type: ERW - Cold Rolled
Grade: C1010
Specification and Finish: ASTM A513 Type 2, As Wleded, Cold Rolled
Description: Cold Rolled Electric-Resistance Welded (ERW) Carbon Steel Mechanical Tubing. Excellent forming quality tubing. A513 Type 2 can be purchased with ID weld flash-in, flash controlled, or flash removed. It is produced from cold rolled steel in commercial quality or plating quality and is slightly more expensive than hot rolled as-welded.
Typical Applications: Good for use in light structural applications, frames and furniture.Suitable for painting or plating, where surfacefinish is important.
Typical Mechanical Properties:
Tensile Stregth: 45,000 PSI
Yeild: 32,000 PSI
Elongation: 15% min.
Hardness: 55 Rockwell B
Fabrication Characteristics:
Weld-Ability: Good
Machine-Ability: Good
Tube Type: DOM
Grade: C1010
Specification and Finish: ASTM A513 Type 5, Drawn Over Mandrel (DOM)
Description: DOM is cold drawn through a die and over a mandrel resulting in improved surface finish, excellent concentricity and dimensional accuracy. Lower costalternative to CDS with equal or superior physical properties.
Typical Applications: Can be used formachined parts, rollers, shafts, sleeves and is most readily adaptable in cylinder applications.
Typical Mechanical Properties:
Tensile Stregth: 60,000 PSI
Yeild: 50,000 PSI
Elongation: 10%
Hardness: 73 Rockwell B
Fabrication Characteristics:
Weld-Ability: Good to Excellent
Machine-Ability: Good
Tube Type: Cold-Drawn Buttweld
Grade: C1010
Specification and Finish: ASTM A512, Cold-Drawn Buttweld Carbon Steel Mechanical Tubing
Description: Buttweld mechanical tubing is made from buttwelded or continuous welded tube hollows, drawn to size with a mandrel. The tubing is cold drawn for the purpose of obtaining dimensional accuracy and improved mechanical properties. Excellent surface finish and machinability. Produced to closer tolerances than ERW, A513 Type 1 & 2. A512 is considered an acceptable low cost substitute for DOM and cold drawn seamless in non-pressure applications.
Typical Applications: Can be used for structural applications, bushings, spacers, sleeves, or for many upsetting, flaring, and bending applications including axles, truck and railroad parts, and many more where weight-to-strength ratio and tolerances are important.
Typical Mechanical Properties:
Grade C1010
Tensile Stregth: 63,000 PSI
Yeild: 58,000 PSI
Elongation: 15%
Hardness: 70 Rockwell B
All "Tube" Weight Per Foot:
1" OD x .834" (.083" Wall) = .81 lbs.
1" OD x .810" (.095" Wall) = .92 lbs.
1" OD x .782" (.109" Wall) = 1.04 lbs.
1" OD x .760 (.120" Wall) = 1.13 lbs.
Tube Type: Pipe
Grade: B (.30 Max Carbon)
Specification and Finish: A53 Welded or Seamless, "Scheduled" Pipe
Description: Hollows produced to ID dimension with schedules denoting wall thick-ness. Generally used for conveying liquid and gases. Used predominantly in long lengths coupled together.Available in pipe sizes and mechanical tube sizes.
Typical Applications: Rolls, machined parts, and pipe lines for conveyance of liquids or gases
Typical Mechanical Properties:
Grade B:
Tensile Stregth: 60,000 PSI
Yeild: 35,000 PSI
Elongation: 20%
Grade A: (.25 Max Carbon)
Tensile Stregth: 48,000 PSI
Yeild: 30,000 PSI
Elongation: 20%
Fabrication Characteristics:
Weld-Ability: Good
Machine-Ability: Good
Weight Per Foot: 3/4" Pipe Size (OD = 1.050, Wall = .133") = 1.68 lbs.
Conclusions:
My non-professional opinion/summary based on specs and pricing would lead me towards using Hot-Rolled ERW. Here's why:
1) Weighs less than Schedule 40 pipe
2) Similar strength as Schedule 40 pipe (a bit "harder")
3) Not much more expensive than Schedule 40 pipe
4) Same stuff the entire XS650 frame is made of!!!!!!
5) Not as expensive as DOM Tube
6) Easier to find than DOM tube (especially in the scrap yards, at least more identifiable...)
7) Same stuff the existing frame is made of!!!!!! - not a duplicate/typo, listed again for effect...
Some drawbacks to the ERW:
- not as strong as DOM but then again neither would the rest of the frame be.
- a bit harder to find than Schedule 40 pipe, it would be nice if Home Depot carried ERW!!!
Again, this info is for REFERENCE ONLY and is not intended on recommending any specific type. It seems that, other than DOM being harder/stronger as we all new, the other choices may be viable options based on individual circumstances. (wow what a bs/politically corect load!!!) "
