ASTM A519 GRADE 1010 COLD FINISHED CARBON STEEL TUBING
OVERVIEW
Carbon steel seamless steel pipe is kind of long steel. Steel pipe has hollow section, which is widely used as pipeline for conveying fluids, such as oil, natural gas, gas, water and some solid materials. Compared with solid steel such as round steel, steel pipe is lighter in weight under the same bending and torsional strength. It is an economic section steel. It is widely used in manufacturing structural and mechanical parts, such as oil drill pipe, automobile transmission shaft, bicycle frame and steel scaffolding used in construction.
ASTM A519 GR. 1010 Cold Drawn Seamless Steel Tube is low Carbon Steel Tube, which is one of the most commonly used steel pipes for general purpose applications worldwide.
It has good weld ability and forming and extruding chrematistics. It also has exceptionally simple and robust mechanism, self-cleaning and non-clogging mechanism, power saving, maintenance free, big solid handling capability, and as well as the quality for enduring reliable longer life and performance. 1010 tubing is often used for general structural and automotive bodies.
APPLICATIONS
The low carbon steels, such as 1010, are used for applications such as cold headed fasteners and bolts.

Heat Treatment
This steel is generally used in the annealed or case hardened condition. It may be heat treated, quenched and tempered but the cost for so doing is generally not worth the result.
Forging
Forging may be done in the range of 2300 F down to 1800 F.
Hot Working
The alloy may be hot worked in the range of 900 F to 200 F.
Cold Working
1010 is easily cold worked by traditional means. Following severe cold working a stress relief, or full, anneal should be performed.
Annealing
A full anneal is done at 1600 to 1800 F followed by slow cooling in the furnace. A stress relief anneal may be done at 1000 F and slow cooled. In the full annealed condition 1010 steel has a tensile strength of about 45 ksi.
Tempering
Tempering may be done, after hardening, at 600 to 1100 F depending upon the strength level desired. Tempering at 1000 F will give a tensile strength on the order of 75 ksi.
