Characteristics of ASME SA387 Grade 11 Plate:
- Better Thermal Resistance: While Grade 5 is effective for only medium temperatures, ASME SA387 Grade 11 Plate is effective even in severe heat conditions, and is thus more acceptable for use in pressure vessels and heat exchangers.
- Corrosion Protection is Superior: Grade 11 has a higher content of chromium and molybdenum therefore, it exhibits better resistance to oxidation, sulfidation and several other types of corrosion, especially in harsh environments.
- Higher Strength and Toughness: Grade 11 exhibits significantly better mechanical strength and impact resistance than Grade 5, thus providing reliability in highly stressed situations.
- Excellent Weldability & Fabrication: While both grades are weldable, ASME Sa387 Grade 11 Plate offers easier machinability and forming properties by making it more convenient for fabrication.
- Extended Service Life: It has a longer lifespan compared to Grade 5, reducing maintenance costs in industrial applications.
Compositions and Properties of ASME Sa387 Grade 11 Plate
The strength and durability of the ASME SA387 Grade 11 Plate are well-balanced composition. The chromium content is in the range of 1.00-1.50% which makes the plate resistant to oxidation, while the molybdenum content of 0.45-0.65% gives the plate excellent performance at high temperatures. The carbon content ranges from 0.05-0.17%, which helps to give outstanding tensile strength, whereas toughness is increased by manganese( 0.40-0.65%). These chemical properties make the plate highly reliable in extreme thermal and pressure conditions ensuring longevity and durability in demanding environments.
Applications of ASME Sa387 Grade 11 Plate
Our ASME Sa387 Grade 11 Plates are used in highly elevated temperature and pressure conditions. It is extensively used in the production of boilers, heat exchangers and pressure vessels, and hence it is essential in industries such as petrochemicals, power generation and refineries. Its superior mechanical properties also make it useful for offshore platforms and marine engineering, where resistance to extreme conditions is vital. Additionally, this plate is also used for structural purposes in thermal power plants and process piping systems because of its superior durability and reliability.
Packaging, Testing, and Delivery
We emphasize quality control through rigorous testing and safe packaging. Each UNS K11789 Plate is ultrasonically tested and mechanical properties are tested before despatch. We pack in with a proper wooden box, waterproof wrapping and clear labeling to prevent transit damage. Being a trusted ASTM A387 GR.11 CL.2 Steel Plates Supplier in India, we assure timely delivery in domestic and international markets.
