What are 253 MA [S30815] Round Bar?

253 MA, UNS S30815, is an austenitic stainless steel alloy designed for high temperature applications in corrosive environments. Its round bar features the benefits of chrome, nickel, as well as nitrogen combined with the addition of rare earth metals, thus achieving excellent high temperature resistance as well as superior oxidation resistance. It is particularly ideal for uses that involve long service at high temperatures.

One of the main benefits of the 253 MA Round Bar is that it has high tensile and creep strengths, making it suitable for structural parts that come under severe conditions. It is highly weldable and can be fabricated easily with standard fabrication means, thereby broadening its applications in different fields of engineering and industry. Its high resistance towards oxidation allows it stability in oxidizing environments even at high temperatures under continuous load.

It is the combination of heat resistance and mechanical strength that makes the 253 MA Round Bar stand out. It has great mechanical properties up to 1150°C (2100°F) and provides excellent carburization, sulfidation, and oxidation resistance. Its fine structure and microstructure render it significantly resistant to thermal fatigue in relation to most other stainless steel grades, increasing efficiency in operation and lowering maintenance downtime.
