#For LPG service, storage tanks are made with SA 516 Gr. 60 as this grade is a boiler quality plate.
#SA 516 Gr. 60 is a material standard accepted all over the globe for steel plates.
Full standard is : ASTM A 516 GR 60
# ASTM A 516 or ASME SA 516 :
ASTM A 516 or ASME SA 516 grade is one of the most popular steel grades.
It is primarily intended for use in welded pressure vessels where notch toughness is important. These grades cover a range of tensile strengths from 55 - 90 MPa and this versatility explains much of the specifications popularity.
For plates thinner than 40mm normally supply as rolled. Plates above 40mm thick are normalised.
[For A 516 grade 70, which is one of most popular steels, the ASME standard composition is as follows (dependent on grade):
Carbon 0.27 - 0.31%
Manganese 0.79 - 1.3%
Phosphorous 0.035% max
Sulphur 0.035% max
Silicon 0.13 - 0.45% ]
#What is the carbon content allowed in SA-516 Gr 60 with respect to plate thickness?
For thicknesses < 12.5 mm C < 0.21%, for thicknesses > 12.5 mm C < 0.23%
[The ASME equivalent of P355NH grade is SA516 Gr.60.]
