A515Gr70 steel plate  Introduction

There are three steel grades A515 Grade 60 boiler steel plate,A515 Grade 65 boiler steel plate and A515 Grade 70 boiler steel plate owning to different yield strength and tensile strength.Pressure vessel steel plate A515Gr70 owned tensile strength within 485-620 Mpa,and the minimum yield strength shall be above 260 Mpa.The steel grade A515 Grade 70 contains a higher carbon contains comparing with A515 Grade 60 and A515 Grade 65.

A515Gr70 Steel plate Application

A515gr.70 steel plate has good toughness and low effectiveness of the tendency in the use of bending, curling, deformation processing such as cold, after more prolonged storage and use remains a good toughness,A515gr.70 steel plate also has good weldability and resistance to intergranular corrosion. For the manufacture of boiler drum, beams and wall panels. 

ASTM A515 standard specification for pressure vessel plates, carbon steel, for intermediate-and higher-temperature service.
