A516Gr70 usual request normalized if thickness above 40mm, if not , BBN Steel usual delivery in hot rolled or control rolled station. A516 Gr.70+N or A516gr70N mean that steel grade must be normalized in any thickness.
Compare with the A516Gr60, A516Gr65, and A516Gr55, the A516Gr70 steel grade have better property in tensile and yield strength.BBN Steel also supply the Ultrasonic test in thickness in A 435/A435M, A 577/577M and A 578/A578M to promise the perfect quality in long cooperation.
Our plates including A516Gr70 come with mill certificate in accordance with EN 10204 3.1 or EN 10204 3.2. We welcome any third party or customer inspection if required.
