What Materials Are Used in Pressure Vessels?
Pressure vessels need materials that won’t crack, corrode, or deform under high pressure and temperature swings. Common choices are titanium, nickel alloys (incl. Hastelloy), stainless steel, carbon steel, and aluminum each a tradeoff between corrosion resistance, strength at temperature, fabrication complexity, and cost. Understanding What Materials Are Used in Pressure Vessels When you need to handle gas or liquid under high pressure, it’s natural to ask what materials are used in pressure vessels, especially if you’re evaluating a trusted pressure
