The ASTM A387 Grade 12 Plate is known for its excellent heat and pressure resistance and superior performance under conditions in which other types of steel would fail. The exceptional ability of A387 Grade 12 to withstand extreme heat and heat-related conditions, and to provide exceptional resistance to mechanical failure under extreme heat, makes A387 Grade 12 Alloy Steel our number one choice for critical pressure vessels. A387 Grade 12 is also one of the most commonly used materials in the oil and gas industry; chemical processing industry; and electric power generation industry.

What Is ASTM A387 Grade 12 Alloy Steel Sheets & Plates?


ASTM A387 Gr 12 Steel is a chromium-molybdenum alloy steel. It is a material crafted primarily for use in welded boilers and pressure vessels. These vessels operate in elevated temperature service. The key chemical elements are chromium (Cr) and molybdenum (Mo). Chromium boosts corrosion and oxidation resistance. Molybdenum adds strength at high temperatures. These sheets and plates offer superior strength, excellent durability, and high thermal resistance. They maintain their integrity even when exposed to intense heat and pressure over long periods. Unlike plain carbon steel, this alloy is built to perform reliably in harsh, demanding environments. This specialized composition is what sets it apart from other common alloy steels.
