A516, PVQ 516-70 Steel Plate
A516 steel plate, also known as PVQ 516-70 steel plate, is carbon steel plate with specifications for pressure vessel plates and moderate or lower temperature service. A516 steel plate is intended primarily for service in welded pressure vessels where improved notch toughness is important. Plates 1.50” and under in thickness are normally supplied in the as-rolled condition. The plates may be ordered normalized or stress relieved, or both. Plates over 1.50” in thickness shall be normalized.
Chemical Requirements:
- Carbon range is .18 to .31 depending on grade & thickness
- Manganese range is .60 to 1.30 depending on grade & thickness
- Phosphorous maximum is .035
- Sulfur maximum is .035
- Silicon can range from .15 to .40
Mechanical Requirements:
- Grade 55 – 30,000psi yield strength, 55,000psi to 75,000psi tensile strength, 23% elongation in 8” test, 27% elongation in 2” test. Maximum thickness is 12”.
- Grade 60 – 32,000psi yield strength, 60,000psi to 80,000psi tensile strength, 21% elongation in 8” test, 25% elongation in 2” test. Maximum thickness is 8”.
- Grade 65 – 35,000psi yield strength, 65,000psi to 85,000psi tensile strength, 19% elongation in 8” test, 23% elongation in 2” test. Maximum thickness is 8”.
- Grade 70 – 38,000psi yield strength, 70,000psi to 90,000psi tensile strength, 17% elongation in 8” test, 21% elongation in 2” test.
Note: Mechanical requirements are minimums unless there is a range listed.
