Stainless Steel SA 253 MA Fitttings have many excellent characteristics, so these fittings are used in various applications. These Fitttings are manufactured at Navgraha Steel & Engg Company as per industrial, national and international standards. This grade of Stainless Steel is mostly used because it fabricates easily and is also easily machined to form a pipe fitting. Customers can get these Fitttings in various specifications, types, sizes, and lengths as per their needs. This grade is very flexible and mostly used grade. These Fitttings show good weldability and formability. We use only the best quality raw materials to design these Fitttings. These Fitttings are safe to use. These products maintain their stability in various critical applications.
Stainless-Steel SA 253 MA composition and characteristics:
These Stainless-Steel SA 253 MA Fitttings contain various elements. These chemical elements are as follows:
• Chromium
• Silicon
• Manganese
• Nickel
• Molybdenum
• Phosphorous
Due to these elements, our Fitttings are very suitable to use in various applications. These Stainless-steel SA 253 Ma Fitttings have many properties, such as:
• Superior oxidation endurance to 2000°F
• Eminent creep-rupture strength
Features of SA 253 MA Fitttings:
They have high tensile strength, excellent resistance to oxidation at high temperatures, and high creep rupture strength. Thus, these Fitttings offer a good combination of the creep strength and high resistance to oxidation, sulfidation, and erosion at exceptionally high temperatures.
• Durability
• weldability
• Anti-oxidation Strength
• Higher thermal range
Stainless Steel SA 253 MA Fitttings offer strong resistance to isothermal and, in particular, cyclic oxidation, outstanding resistance to combustion gases, superior structural stability at elevated temperatures, and good weldability. These Fitttings have a significant strength at elevated temperatures and are often used for structural and pressure-containing applications as well as at elevated temperatures. In addition, these Fitttings have mechanical properties like strength at high pressure and hardness.
Applications of these Fitttings in various industries:
• Energy Industry
• Chemical Industry
• Power Plant Industry
• Aerospace Industry
• Oil and Gas industry
These fittings are also utilized in different applications such as Burners, Boiler Nozzles, Heat Exchangers, Expansion Below, Combustion Chambers, etc.
