A515Gr.70 carbon steel plate 

Durable hot-rolled carbon steel plate manufactured to ASTM A515 Grade 70 specification, designed for intermediate- and higher-temperature service where elevated strength and good weldability are required. Plates are produced with killed steel practice and coarse austenitic grain size control; chemical and mechanical properties are verified by tension testing to meet the standard requirements.

Key features
