ASTM A203 Nickel-Alloy Steel Plates

ASTM A203/ A203, is the standard specification covers nickel-alloy steel paltes intended primarily for welded pressure vessels. These nickel alloy steels are mainly used for moderate- or low-temperature services. The nickel content added imparts significant improvements in fracture toughness and fatigue resistance of the steel. Plates under this specification are available with four strength levels and two nickel compositions:  Grade …

ASTM A537 Heat-Treated Plates

ASTM A537/ A537, is the standard specification covers heat-treated carbon-manganese-silicon steel plates. Carbon steel plates made in accordance with ASTM A537 are primarily intended for fusion welded pressure vessels and structures. Steel plates under this specification are available in three classes classified according to the different heat treatment: Class 1 (normalized), Class 2 (quenched and tempered) and Class 3 (quenched …

ASTM A516 Pressure Vessel Plates

ASTM A516/ A516, identical with ASME SA-516/ SA-516M, is the standard specification for carbon steel pressure vessel plates for moderate- and lower-temperature services. Carbon steel plates made in accordance with ASTM A516 are primarily intended for service in welded pressure vessels where improved notch toughness is important. They can also be used for the manufacture of electric-fusion-welded steel pipes in …

ASTM A515 Pressure Vessel Plates

ASTM A515/ A515M, identical with ASME SA-515/ SA-515M, is the standard specification for carbon-silicon steel plates primarily used for intermediate- and higher-temperature service in welded boilers and other pressure vessels. Hence, plates manufactured in accordance with ASTM A515, are also called as “intermediate-temperature pressure vessel plates” or “higher-temperature pressure vessel plates”. Plates under this specification are classified into three grades …

ASTM A36 Carbon Structural Steel

ASTM A36/A36M, identical with ASME SA-36/SA-36M, is the standard specification for carbon structural steel. This specification covers carbon steel shapes, plates, and bars of structural quality for use in riveted, bolted, or welded construction of bridges and buildings, and for general structural purposes. Structural products furnished under this specification shall conform to the general requirements of ASTM A6/A6M. When the …
