SA516Gr70 pressure vessel steel plate Detailed introduction
First, SA516Gr70 pressure vessel steel plate is a common low-temperature low-alloy steel material, commonly used in the manufacture of various pressure vessels and boilers, such as shells, heads and tube plates and other components. The steel has good corrosion resistance, low temperature toughness and high strength, etc. It has good toughness and plasticity in low temperature environment and can withstand higher pressure and temperature.
Second, the characteristics of SA516Gr70 pressure vessel steel plate are as follows
1. good weldability and workability;
2. high strength and ductility;
3. good corrosion resistance;
4. suitable for use in high and low temperature environments.
The parameters of SA516Gr70 pressure vessel steel plate are as follows
1. thickness range: 5-200mm;
2. width range: 1500-4020mm;
3. length range: 3000-27000mm;
4. Standard: ASTM A516/A516M.
Common problems that may occur in the use of SA516Gr70 pressure vessel steel plate include
1. hydrogen cracks may occur during the welding process;
2. brittle fracture may occur under high temperature conditions;
3. stress corrosion cracking may occur in the process of use.
