  ASTM A135 GR.A Electric-Resistance-Welded Steel Pipe/tube

ASTM A135 Standard Specification for Electric-Resistance-Welded Steel Pipe.

A135 Grade A steel pipe is intended for conveying gas, vapor, water or other liquid; only Grade A is adapted for flanging and bending.

Shanghai Katalor Enterprises, as a A135 grade A Welded Steel Pipe/tube Manufacturer, has advanced production equipment and a professional working team. We also have strict implementation of quality management system, so we can offer the A135 grade A Welded Steel Pipe/tube in high quality and best processing service.

A135 grade A chemical composition

Element Carbon Manganese Phosphorus Sulfur
Grade A 0.25 0.95 0.035 0.035

A135 grade A Welded Steel Pipe/tube mechanical properties

  Grade A
Tensile strength, min, ksi (MPa) 48 (331)
Yield strength, min, ksi (MPa) 30 (207)
Elongation in 2 in. (50 mm), min, %:  
For pipe having a specified wall thickness of5 ⁄16in. (7.9 mm) or more, if tested using a longitudinal strip test specimen 35
For pipe having a specified wall thickness of less than5 ⁄16 in. (7.9 mm), if tested using a longitudinal strip test specimen A
For pipe of any size, if tested using a full-size longitudinal test specimen 35

A The minimum elongation shall be determined by the following equation, with the calculated value rounded to the nearest percent:
E556t116.5
where:
E = elongation in 2 in. (50 mm), minimum, %, and
t = specified wall thickness, in
