ASME SA738 Grade A Hot Rolled Boiler Plate

ASME SA738 Grade A Hot Rolled Boiler Plate

Product:ASME SA738 Grade A is a kind of C-Mn-Si steel plates material used to fabric middle or low temperature pressure vessels. Obviously, SA738 is divided into three grades or levels :SA738 Gr. A, SA738 Gr. B, SA738 Gr. C . In order to meet the property requirement of ASME SA-738/SA-738M standard, this material must be done heat-treatment.

Key words:SA738 Grade A,ASME SA738 Grade A,SA738 Grade A high strength low alloy steel plates,SA738 Grade A for fabric pressure vessels,SA738 Grade A high strength low alloy steel plates for pressure vessels
