ASME SA656 is a series of high-strength low-alloy steel plates. This type of steel plate can improve its weldability, formability, and notch toughness in the rolled condition.
ASME SA656 is a type of high-strength low-alloy steel plate, with its main characteristics reflected in the following aspects:
High strength: It has excellent strength characteristics, making it perform exceptionally well in various applications that require high loads to be borne.
Good weldability: It exhibits good welding performance in the rolled state, making it easy to connect with other components during the manufacturing process, thus improving work efficiency.
Excellent formability: With good formability, it can adapt to various complex shape designs and meet diverse manufacturing needs.
Excellent notch toughness: A has excellent notch toughness, which means it can resist fracture when subjected to impact or stress concentration, improving the overall stability and safety of the structure.
The chemical composition of ASME SA656 mainly includes carbon (C), manganese (Mn), phosphorus (P), sulfur (S), silicon (Si), vanadium (V), nitrogen (N), and niobium (Nb).
The specific chemical composition percentages of ASME SA656 Grade 3 and Grade 7 steel plates have the same upper limits for carbon, manganese, phosphorus, sulfur, and silicon, which are C≤0.18%, Mn≤1.65%, P≤0.025%, S≤0.035%, and Si≤0.60% respectively. However, the content of vanadium and nitrogen is slightly different. In Grade 3 steel plates, the content of V is 0.08% and N is 0.020%; while in Grade 7 steel plates, the content of V is 0.15% and N remains at 0.020%.
Construction equipment: Its high strength and good weldability make it perform well in building large structures and equipment.
Crane lifting beam: It has excellent formability and notch toughness, so it is often used in the manufacturing of lifting beams for cranes. When lifting heavy objects, this type of steel plate can withstand high loads and maintain the stability of the structure.
Car chassis: widely used in the field of car manufacturing, especially for making car chassis. Its high strength and good formability enable the chassis to withstand various stresses and impacts during vehicle operation.
General manufacturing: In addition to the specific applications mentioned above, ASME SA656 steel plates are also suitable for general manufacturing industries, such as machinery manufacturing, equipment manufacturing, etc.
In addition, ASME SA656 steel plates are also suitable for low-temperature environments, allowing them to perform well in certain working conditions, such as cold regions or refrigeration equipment.
The delivery condition of ASME SA656 steel plate is usually hot rolled or controlled rolled. In this condition, the steel plate has
