A53 Carbon steel round bar
Classification :
PRODUCT DETAILS
A53 is an ASTM standard specification for welded and seamless steel pipe. It is not a standard grade for "round bar". Round bars of similar composition are typically supplied under standards such as ASTM A36 for structural shapes or ASTM A29 for hot-rolled carbon steel bars.
|
Material |
Carbon Steel (for pipe application). Note: "A53" is a standard for welded and seamless steel pipe, not a plate/round bar material designation. |
|
Thickness |
For Pipe Wall Thickness: Commonly corresponds to schedules (e.g., Sch. 40, 80) or specified wall. The stated range (0.1mm-300mm) is incorrect for this product standard. |
|
Standard |
ASTM A53 / ASME SA53 (Type F, E, or S; Grade A or B) |
|
Technique |
Welded (ERW, Furnace Butt-Welded) or Seamless (for steel pipe). "Hot rolled, cold rolled" is incorrect for ASTM A53 pipe manufacturing. |
|
Surface Treatment |
Clean, blasting and painting according to customer requirement. (Note: Standard finish is bare/as-manufactured; galvanized coating is a common option.) |
|
Thickness tolerance |
Per ASTM A53, wall thickness tolerance for seamless pipe is typically +20%, -12.5% of nominal wall; for welded pipe, it varies by process and size. The stated ±0.1mm is incorrect. |
|
Application |
General service steel pipe for conveying fluid (water, gas, air, steam) and structural applications. The description related to automotive structural parts is not the primary application for ASTM A53 pipe. |
|
Shipment time |
Within 7-15 workdays after receiving deposit or L/C |
|
Export packing |
Waterproof paper, and steel strip packed. Standard Export Seaworthy Package.Suit for all kinds of transport,or as required |
|
Capacity |
250,000 tons/year |
Round steel belongs to carbon structural steel for construction and machinery, while square steel belongs to carbon structural
steel for machinery. Both of them are simple section steel, and their section shapes are respectively round and square. Low carbon is mainly used for
drawing wire, forging rivets, bolts, nuts and other metal products of raw materials. Medium carbon round steel and square steel
are generally used to make mechanical structural parts.
