ASME-SA516-Grade-70-SA516-Grade-60-Steel-Plate



ASTM/ASME SA516 Carbon Steel Plate for Pressure Vessels:

ASTM/ASME SA516 specification covers carbon steel plates produced mainly for application in welded pressure vessels where improved notch toughness is important. Tensile strength range is from 55 - 90 MPa and its versatility makes this specifications very popular in application.

ASME SA516 grade introduction:
SA516 grade 55, SA516 grade 60, SA516 grade 65, SA516 grade 70. These 4 grades are mainly defined by their different tensile and yield strength range, which is influenced by content of Carbon. For example sa 516 grade 70 has the highest tensile and yield strength range due to the highest Carbon content(up to0.28%). For higher grade like sa516 gr-70 steel plate, preheating might be needed for metal arc welding process, especialy with thick steel plate.

Delivery State:
SA516-70n reffers to normalized steel plate product, for steel plate and sheet thinner than 40mm we normally supply them as rolled-steel coil. Plates with thickness above 40mm  are supplied normalized. SA516 grade 70 steel plate density is 0.284 cu/in3 (7861 kg/m3).

Mild test:
ASME SA 516-carbon steel plates are manufactured with mill certification following EN10204 3.1 or EN10204 3.2 standard version.
Inspection: MOODY SGS BV GL DNV ABS LIOYD’S Test: X-ray, UT, magnetic particle, inspection.
