Seamless 253MA Stainless Steel Pipe ,also known as UNS S30815 seamless stainless steel Pipe too, is a high-temperature alloy that combines excellent service properties with ease of fabrication. Let’s explore its applications across various industries:
Remember that 253MA is a versatile material, offering oxidation resistance, creep strength, and toughness.
Despite its lean nickel content, 253MA offers an outstanding combination of creep strength and high resistance to oxidation, sulphidation and erosion/abrasion at extremely high temperatures. This makes the alloy more economical than most heat resistant alloys.
The high heat resistant properties of 253MA are obtained by the tight control of micro alloy additions. Whilst the benefit of creep rupture strength is down to the combination of nitrogen, carbon and cerium, its superior oxidation resistance is a result of the combination of cerium and silicon.
Its strength at these temperatures is higher than that of alternatives such as Grade 310.
TP310MOLN/S31050 Seamless Stainless Steel Pipe ,310MoLN stainless steel, also known as UNS S31050, is a fully austenitic stainless steel with optimized properties for specific applications. Let’s explore its characteristics and where it finds use in various industries:Urea Plants:310MoLN is specifically designed for applications in urea plants.It provides improved corrosion resistance in urea carbamate environments, such as high-pressure strippers.The nitrogen content in its chemical composition helps stabilize and strengthen the austenitic phase.Chemical Processing:Due to its excellent corrosion resistance, 310MoLN is used in chemical processing equipment.It performs well in aggressive chemical environments, including acids and chlorides.High-Temperature Applications:310MoLN is suitable for high-temperature environments.It finds use in furnace components, such as burners, retorts, and conveyor belts.Petrochemical Industry:In petrochemical plants, 310MoLN is employed for tube hangers.Its resistance to oxidation and high-temperature strength are advantageous.Mineral Equipment and Cement Production:Used in mineral processing equipment and cement production due to its high strength at elevated temperatures.Remember that 310MoLN stainless steel offers a unique combination of properties, making it valuable in critical applications.① STANDARD: ASTM A312/ ASTM A249/ ASTM A269/ EN10216-5/GOST 9940 /GOST 9941...② OD RANGE : 6-812MM③ THICKNESS RANGE: 1-65 MM
