SA 387 Gr 11 Plates are chromium molybdenum alloy steel plates used to construct pressure vessels and boilers. The physical properties of these plates make them highly suitable for various applications such as oil and gas production, petrochemical plants, power generation plants, refineries, etc. These plates offer high tensile strength, excellent corrosion and high-temperature resistance, making them popular among industries requiring reliable structural materials.

Additionally, they boast toughness at low temperatures and great ductility & weldability characteristics, further enhancing their suitability for various uses. These features make SA387 Gr 11 Plates an ideal choice for industrial applications.

Composition：

SA 387 Gr 11 plates are made of chromium-molybdenum alloy steel designed for pressure vessels, industrial boilers, and heat exchangers. The combination of elements in the alloy provides improved high-temperature properties compared to other similar-grade stainless steels. This allows for excellent corrosion resistance and strength at high temperatures.

The composition includes 2% – 2¼% chrome, 0¼% – ½ % molybdenum, 0½ – 1% nickel and small amounts of manganese, silicon and nitrogen as possible trace elements. Physical properties include tensile strengths ranging from 65 – 85ksi (450 – 585MPa); yield strengths of 60ksi (415 MPa); hardness up to 19HRc; ductility; impact toughness testing at room temperature with minimum values from 20J to 100J based on plate thickness; and elongation are also important considerations when selecting this material type for any application.

Properties:

SA 387 Gr 11 Plates are made from a combination of chromium and molybdenum, which provides outstanding corrosion resistance and high-temperature strength at elevated temperatures. These plates offer excellent protection from oxidation, pitting, erosion, and wear and tear, even in the most demanding environments. They have good ductility and weldability with or without filler materials, making them highly suitable for welding applications.

Their physical properties, such as tensile strength (minimum 515N/mm2), yield strength (minimum 520N/mm2), elongation (%) minimum 20%, and Brinell Hardness maximum 217HB are some of the best available among alloy steel plates offering superior performance on any application.

Applications:

SA 387 Gr 11 Plates are widely used in various industrial applications, such as oil and gas, power generation, chemical processing, and petrochemical industries. These plates are primarily used in pressure vessels, boilers, heat exchangers, and storage tanks. They are also used in fabricating tanks, hoppers, chutes, and other equipment that require high-temperature resistance and maximum strength.

Advantages:

SA 387 Gr 11 Plates offer several advantages over other types of steel plates. These plates have high-strength-to-weight ratios, excellent weldability, high-temperature resistance, and outstanding corrosion resistance. They are relatively low-cost compared to other high-strength steel alloys, making them an affordable solution for many industrial applications.
