A553 Type 1, Type 2

ASTM A516 / SA516 plate material is the standard specification for pressure vessel fabrication.  ASTM A537 / SA537 plate material is heat-treated, carbon-manganese silicon steel.  ASTM A553 / SA553 plate material is used in the fabrication of cryogenic pressure vessels.

Thickness Size: 6mm – 150mm

Available to JIS, DIN, EN standards.

ASTM A516 Gr. 60, 65

A516 Grade 60, Grade 65 is high quality carbon steel plate material for pressure vessel fabrication with good weldability and notch toughness.  Excellent performance in moderate and lower temperature services.  Used extensively in the Oil & Gas, Petrochemical Industries, Sour Service and wet H2S applications.  All Plates are fully certified in accordance with EN10204 3.1 or EN10204 3.2

Gr.60:  JIS G3118 SGV410,  DIN 17155HII,  BS1501-161-430A,  EN10028 P265GH  Gr.65:  JIS G 3118 SGV450,  DIN 17155 17 MN 4,  BS1501-224-460A/B,  EN10028 P295GH

ASTM A516 Gr. 70

A516 Grade 70 plate material is suitable for low temperature application pressure vessels and industrial boilers. Grade 70 offers greater tensile and yield strength than grade 65 and can operate at even lower temperatures.  As Rolled or Normalised material available ex stock and can be processed and/or cut to size as required. This material is also used extensively for Pipe Shoes, Gussets and Base Plates etc.  Certification in accordance with EN10204 3.1 or EN10204 3.2.

JIS  G3124  SEV245,  BS1501-224-490A/B,  EN10028 P355GH

ASTM A537 Class 1

This grade is normalised, heat treated and displays greater yield and tensile strength than the more common ASTM A516 grades. Ideal for Pressure Vessels and Boilers in the Oil & Gas and Petrochemical Industries.

JIS G3124 SEV245,  EN10028 P355N

ASTM A537 Class 2

Exhibits higher yield and tensile strength. Commonly used in Pressure Vessels and Boilers. High strength Quenched & Tempered alloy steel – Alloys include manganese, silicon and carbon.

JIS G3115 SPV450,  EN10028 P460N

ASTM A553 Type 1

A553 Type 1 grade covers 9% nickel alloy steel plates that are used in the fabrication of cryogenic pressure vessels. A553 Type 1 is capable of operating at temperatures as low as -196°C, and has high levels of strength and weldability.
A martensitic steel when it is quenched or tempered up to 100mm thickness. Commonly used for containing or transporting cryogenic gases, such as nitrogen, oxygen, and argon.

JIS G3127 SL9N590,  DIN X7Ni9

ASTM A553 Type 1

A553 Type 2 grade covers 8% nickel alloy steel plates that are used in the fabrication of cryogenic pressure vessels. A553 Type 2 is capable of operating at temperatures as low as -170°C, and has high levels of strength and weldability.
A martensitic steel when it is quenched or tempered up to 100mm thickness. Commonly used for containing or transporting cryogenic gases, such as nitrogen, oxygen, and argon.
