A203 Pressure Vessel Steel Plate

ASTM A203 grades are: A, B, D, E, F. Boiler vessel plates are nickel alloy steel materials used in the manufacture of high temperature pressure vessels. The performance of ASTM A203 boiler vessel plates is based on their Ni composition. ASTM A203 Boiler Container Plates are available in five grades: Grade A, Grade B, Grade D, Grade E, and Grade F.

A204 Pressure Vessel Steel Plate

ASTM A204 boiler vessel plate is molybdenum alloy steel plate, mainly suitable for welding boilers and high temperature pressure vessels. According to the molybdenum content, ASTM A204 boiler container plate is divided into 3 grades: A, B, C. The thickness of ASTM A204 boiler vessel plates is limited only by the ability of the chemical composition to meet the specified mechanical property requirements.

A387 Pressure Vessel Steel Plate

ASTM A387 Boiler vessel plates are chrome-molybdenum alloy steel plates suitable for welding boilers and high temperature pressure vessels. ASTM A387 boiler container plate is divided into grade 5, grade 9, grade 11, grade 12, grade 22, grade 91 and other grades according to the alloy elements contained. Except for grades 21L, 22L, 91 and 911, each grade of ASTM A387 boiler vessel plate has two tensile strength categories according to its heat treatment: Class 1 and Class 2.

A515 Pressure Vessel Steel Plate

ASTM A515 is the same as ASME SA-515 and is the standard specification for welding carbon steel pressure vessel plates for high temperature service in boilers and other pressure vessels. A515/SA-515 plate can be divided into 3 grades according to its minimum tensile strength: grade 60, grade 65 and grade 70.

JIS G3103 P296GH/P355GH/P235GH Pressure Vessel Steel Plate

JIS G3103 Boiler Container Plate is a hot-rolled plate of carbon steel and molybdenum alloy steel for Chinese and high temperature boilers and pressure vessels. The main grades of JIS G3103 boiler vessel steel are: SB410, SB450, SB480,SB450M and SB480M.

DIN 17155 Pressure Vessel Steel Plate

DIN 17155 pressure vessel steel plate is boiler and pressure vessel steel. In addition to boilers and pressure vessels, DIN 17155 pressure vessel steel is also used to manufacture high-temperature liquid transportation pipelines.

A588 Alloy Structural Steel Plate

ASTM A588 steel is a high-strength low-alloy structural steel section, steel plate and bar used for welded, riveted or bolted structures. These steels are mainly used in welded bridges and buildings where weight reduction or increased durability is required. In most environments, the atmospheric corrosion resistance of this steel is significantly better than that of carbon structural steel with or without the addition of copper.

GB/T11251 1345 Alloy Structural Steel Plate

GB/T 11251 alloy steel is one of the common hot-rolled alloy structural steel plates. GB/T 11251 Hot rolled plate has high strength and wear resistance, high hardenability, moderate cold deformation plasticity, good cutting performance and good welding performance. During the heat treatment, the toughness of the steel decreases less. GB/T 11251 alloy steel can still maintain high toughness under water cooling conditions, but it has a tendency of overheating sensitivity, white spot sensitivity and temper brittleness.

EN 10083-3 4135/4140/4142/6150 Alloy Structural Steel Plate

EN 10083-3:2006 steel is an alloy steel used for quenching and tempering. This standard regulates the technical delivery conditions of alloy steels. Under the steel 50CrMo4, 51CrV4, 20MnB5, 34CrMo4, 42CrMo4, 27MnCrB5-2. EN 10083-3 steel plate has high strength, high toughness and good hardenability. The alloy requires high temperature preheating before welding to eliminate the stress after welding.
