SA387Gr11CL1 is also known as ASTM A387 Grade 11 Class 1 steel plate. SA387Gr11CL1 is commonly used in boiler and pressure vessel manufacturing in petroleum, chemical, electric power and other industries.
SA387Gr11CL1 contains lower alloying elements, with the main components including chromium, molybdenum and manganese.
| A387 GR.11 | Carbon | Manganese | Phosphorus | Sulfur | Silicon | Chromium | Molybdenum |
| (Max. %) | |||||||
| Heat Analysis | 0.05-0.17 | 0.4-0.65 | 0.025 | 0.025 | 0.50-0.80 | 1.00-1.50 | 0.45-0.65 |
SA387Gr11CL1 has good tensile strength and yield strength, as well as good toughness. It can maintain good performance stability under high temperature and high pressure conditions.
Due to the presence of the alloying elements chromium and molybdenum, SA387Gr11CL1 has good corrosion resistance, especially for oxidizing and sulfiding media at high temperatures.
SA387Gr11CL1 has good welding performance and can generally be welded by conventional welding methods. However, for welds of high-pressure vessels, corresponding pre-heat and post-heat treatments may be required to ensure the performance and reliability of the welded joints.
SA387Gr11CL1 can perform a variety of processing operations, including cutting, welding, bending and forming. SA387Gr11CL1 processing method:
1. Cutting: Common cutting methods can be used, such as shearing, flame cutting or plasma cutting, etc., to cut the plate to length or shape according to specific requirements.
2. Welding: SA387Gr11CL1 has good welding performance and can use common welding methods, such as manual arc welding, submerged arc welding or gas shielded welding. During the welding process, attention should be paid to selecting appropriate welding materials and welding processes to ensure the quality and performance of the weld.
3. Bending: SA387Gr11CL1 can perform cold bending and hot bending operations, but attention should be paid to controlling the bending radius and temperature to prevent material deformation and cracks.
4. Processing and forming: SA387Gr11CL1 can be processed and formed through stamping, planing, hole making and other operations. The material can be processed and adjusted according to specific engineering needs and design requirements.
