ASTM A36 American Standard Carbon Steel

Table of Contents

American standard carbon structural steel ASTM A36 conforms to the standards of the American Society for Testing and Materials, and is produced according to ASME standards. It is an ordinary carbon steel pipe, equivalent to China’s Q235 material, and belongs to the American standard ordinary carbon steel plate.

ASTM A36 is suitable for riveting, bolting and welding structures used in bridges and buildings, and is often used in machinery manufacturing. ASTM A36 has good cutting and welding performance. In terms of cutting processing, it has stable performance, small cutting deformation and is easy to weld. It is widely used in manufacturing industries such as heavy equipment spare parts manufacturing, metallurgy and chemical industry, and flanges.

The executive standard of ASTM A36: ASTM A36/A36M-03a.
Chemical elements and composition of ASTM A36:

1. Elements: C (carbon), Si (silicon), Mn (manganese), P (phosphorus), S (sulfur), Cu (copper)
2. Composition: C: ≤0.25, Si≤0.40, Mn: ≤0.80-1.20, P≤0.04, S: ≤0.05, Cu≥0.20. (in the case of copper-containing steel)
ASTM A36 technical requirements: flaw detection, Z15Z35 thickness direction performance requirements, high strength, high toughness and other requirements.

Mechanical properties of ASTM A36:

Yield strength——≥250MPa
Tensile strength——400MPa-550MPa
Elongation after break——≥20% (without impact)

Delivery status of ASTM A36:

There are no defects such as cracks, bubbles, and scars on the surface. The delivery status of the steel plate is hot-rolled, and it can be delivered according to technical requirements such as normalizing, tempering, and controlled rolling; flaw detection can be done as 1 probe, 2 probe, and 3 probe; Thickness extension can do z15, z25, z35.

Common specifications of ASTM-A36 steel plates: (thickness*width*length)

ASTM A36: This type of steel can be smelted by oxygen converter, open hearth furnace or electric furnace, and is generally hot rolled into steel plates, steel strips, profiles and bars.

Tips: ASTM A53 covers seamless pipe and welded steel pipe with nominal wall thickness. The surface condition is usually black and hot-dipped galvanized. ASTM A53 is produced mainly for pressure and mechanical applications, and is also used for transport of steam, water, gas line pipes.
