ASTM A572 Gr.55/ A572 Grade 55 HSLA structure steel plates

ASTM A572 Gr.55/ A572 Grade 55 HSLA structure steel plates are American steel with ultimate tensile strength of 65,300 psi and a high tensile yield strength of 50,000 psi. The A572 Grade 55 HSLA structure steel is under ASTM A572/ A572M standard, same as A572 Gr.42 steel, A572 Gr.50 steel, A572 Gr.60 steel and A572 Gr.65 steel.

ASTM A572 Gr.55/ A572 Grade 55 HSLA structure steel plates have e higher yield strength and tensile strength than A572 Gr.42 steel plates and A572 Gr.50 steel plates. But for higher strength, A572 Gr60 and A572 Gr65 structure steel will be more suitable.

The main application of ASTM A572 Gr.55/ A572 Grade 55 HSLA structure steel plates are construction equipment, truck frames, buildings, transmission towers, bridges construction, etc. For more information, please contact BBN steel directly. We would like to give useful suggestions about material choose according to your specific project.
