Key Product Advantages for UNS S30815
 

• Exceptional High-Temperature Performance:​ The UNS S30815 (253MA) grade is micro-alloyed with nitrogen and rare earth elements (Cerium), providing superior oxidation resistance and high creep strength in temperatures ranging from 850°C to 1100°C. This makes it ideal for furnace components, radiant tubes, and heat exchangers operating under severe thermal stress.
• Excellent Mechanical Properties:​ This austenitic stainless steel offers a minimum tensile strength of 600 MPa and a minimum yield strength of 310 MPa, ensuring structural integrity and durability under high-pressure, high-temperature conditions, outperforming standard grades like 304 and 310.
• Good Fabricability:​ The tube features good weldability and formability, allowing for easier fabrication and installation into complex high-temperature systems using common welding methods, which helps reduce overall project complexity and cost.
• Cost-Effective Solution for Demanding Applications:​ By offering a performance level that can approach more expensive nickel-based alloys in many high-temperature scenarios, ASTM A312 S30815 provides an excellent balance of performance and cost-effectiveness for industries such as power generation, petrochemical processing, and mineral processing
