Alloy Steel Plate 387 GR 16MO3 refers to a specific type of steel plate made from a high-strength, low-alloy (HSLA) steel. Here's a breakdown of what that means: - "Alloy Steel" indicates that the steel contains additional elements beyond just iron and carbon, which improves its strength and durability. - "Plate 387" likely refers to the ASTM A387 standard, which covers chromium-molybdenum alloy steel plates for pressure vessels and boilers. - "GR 16MO3" is the grade designation, which tells us the specific composition and properties of the steel. In this case: - "16" indicates the carbon content (0.16% in this case). - "MO3" indicates the molybdenum content (approximately 0.3% in this case). So, Alloy Steel Plate 387 GR 16MO3 is a high-strength, low-alloy steel plate with a specific composition and properties, suitable for use in pressure vessels, boilers, and other applications where strength, durability, and resistance to corrosion are critical.
