A36 product introduction

ASTM A36 is the Ameriacan Standard for carbon structural plates, implemented in accordance with ASTM A36/ A36M-03A for riveted, bolted and welded structures for Bridges and buildings, as well as general purpose structural steel quality carbon steel sections, plates and rods.

Chinese: ASTM 36

Executive standard: ASTM A36/ A36M-03A

Component: C, Si, Mn, etc

Type: American standard carbon structural board

A36 chemical composition

C: ≤0.25, Si≤0.40, Mn: ≤0.80-1.20, P≤0.04, S: ≤0.05, Cu≥0.20 (when specifying copper containing steel).

A36 mechanical properties

Yield strength: ≥250.

A36 steel plate use

This standard applies to riveted, bolted and welded structures used in Bridges and buildings, as well as general purpose structural steel quality carbon steel sections, plates and rods. The yield of A36 steel plate is about 240MP, and the yield value will decrease with the increase of the thickness of the material. Because of the moderate carbon content, the comprehensive performance is better, and the strength, plasticity and welding performance are better matched, and the most widely used.

Impact test of A36 steel plate

Charpy V notch specimens were used in the impact toughness test. The impact toughness index is Akv. For grade B, C and D steel, Akv≥27J is required under different temperature requirements. At different impact temperatures, ASTMA36 is American standard carbon structural plate, according to ASTMA36 / a36m-03a standard. The tensile strength of A36 is 58~80 Ksi (about 400~550MPa) and the yield strength is 36 Ksi (about 250MPa).

Tensile strength: 400-550.

Elongation: ≥20.
