What is the composition of ASTM A387 Grade 22?
Composition: ASTM A387 Grade 22 typically contains around 2.25% molybdenum and 1% chromium, enhancing its strength and resistance to oxidation at high temperatures. Mechanical Properties: This grade offers excellent mechanical properties, making it suitable for use in environments subject to high stress and pressure.
What is the temperature range for ASTM A387?
ASTM A387 steel plate are typically applied in the temperature range from 316℃ to 593℃.
What is the difference between SA387 Grade 11 Class 1 and Class 2?
The difference between SA 387 Grade 11 Class 1 and Class 2 Plate lies in their mechanical properties. However, they both have the same chemical composition. The tensile strength and yield strength of class 2 material is higher than that of class 1, whereas the elongation for class 1 is higher compared to class 2.
What is A387 grade 11 material?
ASTM A387 GR 11 CL 2 Plates is designed with the composition of chemicals such as carbon, silicon, phosphorous, chromium, sulfur, molybdenum, and manganese.
What is A387 GR 5 material?
The ASTM A387 GR. 5 CL. 2 has a molybdenum and chromium alloy, and this grade is most widely used in industrial boilers and pressure vessels. Because of the high molybdenum and chromium, the grade product has a high heat resistance and anti-corrosion properties.
What is SA387 grade 12 material?
Engineered for use in elevated temperature service, ASME SA387 Grade 12 is a chrome molybdenum carbon alloy steel for use in weldable pressure vessels and industrial boilers.
What is the hardness of sa387?
Tensile Strength: 75 ksi - 100 ksi (515 MPa - 690 MPa) Yield Strength: 40 ksi (275 MPa) minimum. Elongation: 20% minimum in 2 inches. Hardness: Typically between 130 and 170 HB.
