A516 Gr70 and A516 GR60

A516 Gr.70 and A516 GR.60 Steel grades A516 GR.70 and A516 GR.60 are both in steel specification ASTM A516/A516M (This standard specification for pressure vessel plates,carbon steel,for moderate and low temperature service) In mechanical property,steel plate grade A516 GR.70 is most common 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 owned a lower tensile strength than A516 Grr.70 within 415-550Mpa and minimum yield strength at 220Mpa. In chemical composition,A516 gr.70 steel has a more range in Carbon contains than A516 gr.60 steel.So A516 gr.70 owned a higher strength in steel property. General additional requirements for steel grades A516Gr70 and A516Gr60 shall be conform to ASTM specification A20/A20M. ------------------- A516 Gr.70 and A516 GR.65 techincals Under ASTM A516/A516M specification for pressure vessel plates,carbon steel,for moderate and low temperature service,according to steel strength,there are four different boiler steel grades,A516 Grade 70,A516 Grade 65,A516 Grade 60 and A516 Grade 55.Among these grades,the higher tensile strength steel grades A516Gr70 and A516Gr65 are mainly used for boiler building end users.   Mechnical property for A516 Grade 65 and A516 Grade 70 pressure vessel steel Grade Yield strength (Mpa) Tensile strength (Mpa) A516-70 260 485-620 A516-65 240 450-585  Find more techincals for boiler steel grades A516Gr.70 and A516Gr.65,contact freely.
