One such material specially crafted for such demanding conditions is the SA 387 GR 12 CL 2 plate. But what makes this steel grade so crucial for heavy-duty machinery, and why is it the go-to choice for industry professionals? In this comprehensive guide, we dive into the details of SA 387 Grade 12 Class 2 plates and their importance in various industrial applications.
Understanding SA 387 Steel Plate
Specifications
The “SA” in SA 387 stands for the American Society of Mechanical Engineers (ASME) designation for pressure vessel plates. Specifically, the SA 387 Grade 12 Class 2 is part of the standard specification for pressure vessel plates, alloy steel, and chromium-molybdenum.
The “387” indicates the specification’s identification number, while “Grade 12” signifies the steel’s grade, which dictates certain chemical and mechanical properties. “Class 2” refers to the grade’s class, which determines its heat-treatment process and corresponds to its tensile strength and resistance to impact.
