The staff with college degree or above accounted for more than 80%, and there were more than A283 grade B CS steel carbon plate 30 professional and technical personnel. The LSAW pipe production line can produce welded pipes with Φ350-1800mm, wall thickness 6-80mm, and length 2-12m.
ASTM A387 steel is the standard specification for pressure vessel plates, alloy steel, chromium-molybdenum. Plates under this standard Hebei Metals supplies include ASTM A387 Grades 2, A283 grade B CS steel carbon plate Grade 12, Grade 11, Grade 22, Grade 22L, Grade 21, Grade 21L, Grade 5, Grade 9, Grade 91. Each grade except Grades 21L, 22L, and 91 is available in two classes of tensile strength levels. These Cr-Mo A387 alloy steel is primarily manufactured for welded boilers and pressure vessels for elevated temperature service.
40Cr steel belongs to alloy structural steel. A283 grade B CS steel carbon plate, 40Cr steel has good comprehensive properties, low temperature impact toughness and low notch sensitivity after quenching and tempering on the basis of high-quality carbon structural steel No. 40. 40Cr steel mechanical properties: tensile strength: ≥ 980mpa, yield strength: ≥ 785MPa, elongation after fracture: ≥ 9%, elongation after fracture: ≥ 45%, impact absorption energy: ≥ 47J. 40Cr steel chemical composition: C: 0.37-0.44, Si: 0.17-0.37, Mn: 0.50-0.80, Cr: 0.80-1.10.
Vanadium element (V element) can refine grains in ordinary low carbon alloy steel, improve the strength and yield ratio and low temperature characteristics after normalizing, and improve the welding performance of steel, A283 grade B CS steel carbon plate included. Vanadium element (V element) is often used in combination with manganese, chromium, molybdenum, tungsten and other elements in structural steel because of its low hardenability under general heat treatment conditions. Vanadium in quenched and tempered steel is mainly to improve the strength and yield ratio of steel, refine the grain size, and pick up the overheating sensitivity.
S355J2 steel plate belongs to European standard low alloy steel, the executive standard is EN10025-2. Delivery status: normalizing, hot rolling or control rolling. S355J2 corresponds to the Chinese Q345D, but the executive standard is different, the chemical composition is slightly different, but their mechanical properties are the same. S355J2 low alloy steel plate tensile strength (MPA): 450-680, impact value: - 20 ℃: ≥ 27J. A283 grade B CS steel carbon plate, S355J2 low alloy steel plate is widely used in bridges, vehicles, ships, buildings, steel structures, etc.
