What's the difference between the A516 Gr.70 steel plate and the A516 GR.60 steel plate?

Steel grades A516 GR.70 steel plate and A516 GR.60 steel plate are both in steel specification ASTM A516/A516M (This standard specification for pressure vessel plates, carbon steel, for moderate and low-temperature service)

Chemical composition comparison: A516 grade 60 VS grade 70 steel

In chemical composition, the A516 gr.70 steel plate has a greater range in Carbon content than the A516 gr.60 steel plate. So A516 gr.70 steel plate?owned a higher strength in steel property.

Mechanical property?comparison: A516 grade 60 VS grade 70 steel

In mechanical properties, the A516 GR.70 steel plate is most commonly used in moderate and low-temperature boilers. It owned a higher tensile strength within 485-620Mpa and yield strength above 260Mpa.

However, steel grade A516 GR.60 had lower tensile strength than A516 Grr.70 within 415-550Mpa and minimum yield strength at 220Mpa.

Equivalent steel grades comparison: A516 grade 60 VS grade 70 steel

From the above A516 grade 60 VS grade 70 steel?in properties and equivalents, we can clearly understand the difference between A516 grade 60 and A516 grade 70?steel. The strength of A516 grade 70?steel is higher than that of A516 grade 60 steel, so the A516 grade 70 steel price is also theoretically higher.

BBN Steel supplies ASTM A516 pressure vessel steel plates with full steel grade levels and sizes. Among those A516 steel grades, A516 grade 60 and A516 grade 70?are used most.
