A537CL1 A537CL2 A537CL3 Asme Sa516

ASME SA516 is a steel plate used in the production of pressure vessels and boilers. It is usually composed of carbon, manganese, silicon, sulfur, phosphorus, aluminum and other elements. A516 is classified according to different strength levels (such as 55, 60, 65 and 70), and the most common one is SA516-70.

Advantages

1. Chemical composition control
The manganese content of asme sa516 with a thickness of up to 40mm is controlled between 0.70% and 1.35%, while the manganese content of thicker steel plates is 1.00% to 1.60%. This helps to optimize the strength and toughness of the steel; the nickel content is limited to a maximum of 0.5%, which helps prevent the steel from being too brittle; the carbon equivalent (CE) is kept below 0.57%, which can control the hardenability of the steel and reduce the risk of cracking during its welding process. The lower the CE value, the better the welding performance of the steel is generally.

2. Good tensile strength
The tensile strength of asme sa516 with a thickness of ≤65mm ranges from 485 to 620 MPa. The tensile strength of thicker steel plates (up to 100mm thick) is between 450 and 585 MPa. The tensile strength of steel plates with a thickness of more than 100mm is maintained between 485 and 620 MPa.

3. High Sectional Shrinkage
The section shrinkage of asme sa516 with a thickness not exceeding 65 mm is 18%. The higher the shrinkage, the better the ductility of the steel when stretched.

4. Good Weldability
A537CL1 A537CL2 A537CL3 asme sa516 has good welding performance. Due to the low carbon content and reasonable alloy element ratio, the steel is not prone to defects such as cracks, pores and slag inclusions during welding, making it suitable for the manufacture of boilers and pressure vessels.
