ASTM A618 High-Strength Low-Alloy Steel Tubing Specification
Seamless square pipe:12*12*0.8mm-280*280*18mmWelded rectangular pipe: 10*5*0.8mm-400*200*14mm
ASTM A618 Standard Specification for Hot-Formed Welded and Seamless High-Strength Low-Alloy Structural Tubing covers grades of hot-formed welded and seamless high-strength low-alloy square, rectangular, round, or special shape structural tubing for welded, riveted, or bolted construction of bridges and buildings and for general structural purposes. These grades are: Grade Ia and Ib; Grade II; and Grade III. When ASTM A618 tubing is used in welded construction, the welding procedure shall be suitable for the steel and the intended service.
ASTM A618 high-strength low-alloy steel tubing shall be made by the seamless, furnace-buttwelded (continuous-welded), or hot-stretch-reduced electric-resistance-welded process.If the results of the mechanical tests representing any heat do not conform to a requirement, retests shall be made.
What are the advantages of ASTM A618 Ia high-strength low-alloy steel tubing in relation to the open sections?
- better static characteristics- lighter construction (about 30% less weight)
- smaller surface (it is necessary to protect about 40% less surface area)
- less resistance to air and liquids
- usable interior space (concrete, cables, wires, pipes ...)
- better visual effect
