ASTM A516 Gr.70 / ASME SA516 Grade 70 Properties

Product: Boiler Plate
Kategori: High Tensile Steel Plate
Grades : A-516 Gr.70
Standard: ASTM/ ASME



Characteristic
Beyond-steel Indonesia provide high tensile carbon steel plate according to ASTM A516 Grade 70 and ASME SA516 Grade 70 for boiler and pressure vessel fabrication of the oil, gas and petrochemical industry.
ASTM A-516 standard is primarily used in welded pressure vessels where improved notch toughness is required. The steel plates allow four different strength levels 55, 60, 65, 70 and the most common is grade 70. This grade is made to a fine grain particle size to meet the requirement of varied industry applications.
ASTM A-516 Gr.70 steel plates are HIC tested, made from carbon-manganese steels and are suitable for the fabrication of welded pressure vessels designed for moderate and lower-temperature service requiring excellent notch toughness.
ASTM A516 and ASME SA516 normalized steel plate products are produced to pressure vessel quality (PVQ) standards as delineated in ASTM A20/ASME SA20.


Equivalent
ASTM A285, ASME SA285, ASTM A516, ASME SA516, ASTM A537, ASME SA537, EN 10028, BS 1501, DIN 17155, Cryogenic Steel

Weldability

Each of the A516/SA516 normalized products can be welded using a low-hydrogen electrode and Shielded Metal Arc Welding (SMAW), Gas Metal Arc Welding (GMAW) or Submerged Arc Welding (SAW) processes. When weldability is a concern, Beyond-steel offers more restrictive CE limits of 0.45 and 0.43. It is recommended that welding be conducted in accordance with the applicable ASME/AWS codes.


Formability

Because the normalizing process results in a homogenous, fine-grained ferritic microstructure, plates produced by this process exhibit excellent formability. Nevertheless, it is recommended that the cold bending guidelines of A20 Appendix X4 be followed.
