Stainless Steel 253MA Pipes & Tubes Supplier, Stockist & Exporter
Vivid Steel & Engineering Co. supplies Stainless Steel 253MA Pipes and Tubes for high-temperature, oxidation-resistant and creep-resistant applications. Also known as UNS S30815 / EN 1.4835, 253MA is an austenitic heat-resistant stainless steel alloyed with chromium, nickel, nitrogen and rare-earth elements.
253MA stainless steel is designed for demanding elevated-temperature service where oxidation resistance, creep strength, thermal cycling resistance and structural stability are important. The grade is used in applications such as radiant tubes, furnace components, heat-treatment equipment, rotary kilns, exhaust systems, power-generation equipment and other high-temperature industrial installations.
Vivid Steel & Engineering Co. can supply 253MA pipes in seamless and welded configurations, subject to size, specification, manufacturing route and project requirements.

PRODUCT TYPES — 253MA PIPES & TUBES
253MA Seamless Pipes
Manufactured without a longitudinal weld seam, seamless 253MA pipes are suitable for demanding applications where high-temperature performance and pressure-containing capability are required.
253MA Welded Pipes
Welded 253MA pipes are manufactured from stainless steel strip or plate and formed and welded according to the applicable manufacturing specification. They can be an economical option for larger diameters and fabricated systems where the applicable product standard permits welded construction.
253MA Tubes
253MA tubes are available for applications including: 1. Furnace tubes Radiant tubes Recuperator tubes Heat-treatment equipment Boiler and high-temperature equipment Industrial heating systems
253MA Round Pipes
Round 253MA pipes and tubes can be supplied in standard nominal pipe sizes or specified outside diameter × wall thickness dimensions.
253MA High-Temperature Tubes
Designed for equipment exposed to elevated temperatures, thermal cycling and oxidation.
