Why Steel Grade Matters in Pressure Vessels
Think of a pressure vessel like a balloon—but one that holds gas or liquid under high pressure. You definitely don’t want it popping. That’s why the steel you use has to meet strict performance standards. The right grade ensures the vessel can withstand extreme pressure, temperature changes, and corrosion—without cracking under stress.
Common Steel Grades for Pressure Vessels
Here’s where things get real. For pressure vessel applications, you’ll often see steel grades like SA516, SA387, or Q345R. These are known for:
-
High tensile strength
-
Excellent weldability
-
Good impact resistance (even in cold weather)
TAIGANG STEEL manufactures a range of pressure vessel-grade steels that check all these boxes. Whether it’s carbon steel for general use or alloy steel for high-temperature environments, they’ve got you covered.
Matching the Grade to the Application
It’s not one-size-fits-all. For example:
-
SA516 Grade 70 is perfect for oil and gas tanks.
-
SA387 Grade 11 works well for high-temp boilers.
-
Q345R is widely used in Chinese pressure vessel designs.
No matter what industry you’re in—chemical, petrochemical, or energy—TAIGANG STEEL offers materials tailored to your exact needs.
