Key Features of ASME SA387 Grade 12 Plate
- Superior Strength: Compared to ASME SA387 Grade 11, ASME SA387 Grade 12 Plate offers enhanced tensile strength and better heat resistance, making it ideal for applications that experience higher thermal stress.
- Corrosion Resistance: Improved molybdenum composition offers enhanced corrosion resistance, ensuring that ASME SA 387 GRADE 12 Class 1 is tougher than ASME SA387 Grade 5 in corrosive-prone environments.
- High Temperature Performance: It excels in maintaining strength at elevated temperatures, outperforming other grades like ASME SA387 Grade 22, which is more prone to degradation under similar conditions.
- Versatility: With its excellent formability and weldability, the Grade 12 Plate can be used in a variety of critical applications, from pressure vessels to heat exchangers, making it more versatile compared to other grades.
Compositions and Properties of ASME SA387 Grade 12 Plate
Our ASME SA387 Grade 12 Plate contains a balance of chromium and molybdenum, making it highly resistant to oxidation and corrosion at elevated temperatures. The alloy contains about 2.25% molybdenum and 1% chromium, which give the plate the capacity to withstand heat without compromising tensile strength and toughness. These components improve the steel’s capacity to resist deforming in structures that are subjected to high pressure and heat. With such unique composition, it is the perfect material for applications demanding superior resistance to thermal fatigue, corrosion, and creep.
Uses of ASME SA387 Grade 12 Plate
The superior characteristics of ASME SA387 Grade 12 Plate, make it the material of first choice in most applications. It is widely employed in the manufacture of pressure vessels, heat exchangers, and boilers where high strength, resistance to oxidation, and longevity at elevated temperatures are essential. Its corrosion resistance also makes it ideal for harsh chemical environments, such as in the petrochemical sector. The plate is also used in the production of parts for power plants and refineries, providing the durability and efficiency of equipment under harsh conditions. These attributes make SA 387 GR.12 CL.2 Plate vital in industries demanding strong performance from their materials.
