A285 | Pressure Vessel Steel

A285 | Pressure Vessel Steel

A285 is a low to intermediate-tensile strength carbon steel mainly used for pressure vessels and boilers. It comes in three grades: A, B, and C. The “A” represents moderate strength, and “285” refers to the minimum yield strength. A285 has good weldability and moderate strength. Equivalent grades: EN10028-2 P235GH. It’s used for oil tanks, boilers, and heat exchangers.

Description

What is A285?

A285 is a low to intermediate tensile strength carbon steel for pressure vessel plates. It contains 0.17-0.27% carbon and 0.9-1.3% manganese, supplied as flat plates made by hot rolling. Available in three grades: A, B, and C, it offers good weldability and moderate strength, suitable for pressure vessels, boilers, oil tanks, and heat exchangers where high strength isn’t needed. It meets the ASTM A285 standard.

Why Choose A285 Pressure Vessel Steel?

Are you looking for dependable steel for pressure vessels, boilers, or oil tanks? A285 could be just what you need. At Steel Pro Group, we recommend A285 for its excellent weldability, making fabrication quicker and easier. Its moderate strength ensures safety without excess cost and is widely available, meaning faster delivery and less supply risk. What makes A285 stand out is its balance of strength and weldability. It’s easier to work with than higher-strength steels, saving time and labor. For applications where extreme strength isn’t needed, it’s a perfect, reliable choice. We also offer alternatives like A516 or P355GH for tougher requirements, which handle higher strength and temperatures. These options ensure we’ve got you covered for any project needs.
