253 MA Pipes and Tubes | Modified Alloyed 253 Manufacturer

KVN Steels 253 MA Pipes & Tubes are engineered to deliver high performance in demanding environments where heat resistance and structural stability are paramount. Manufactured from high-temperature austenitic stainless steel containing chromium, nickel, nitrogen, and rare earth metals, these pipes exhibit excellent oxidation resistance and superior mechanical strength. They are available in seamless, welded, and fabricated forms and are offered in a variety of shapes and finishes to suit the needs of complex industrial systems. Our supply capabilities span across India, the United Arab Emirates (UAE), the Kingdom of Saudi Arabia (KSA), Kuwait, Qatar, the Sultanate of Oman, Iran, and Iraq, ensuring prompt delivery and adherence to quality standards globally.

Technical Overview

Classified under UNS S30815 and DIN 1.4835, 253 MA is a specialized stainless steel alloy known for maintaining strength at elevated temperatures ranging from 850°C to 1100°C. Its composition, which includes rare earth elements, enhances its resistance to oxidation and creep deformation. This makes it ideal for thermal cycling and long-term service in high-heat environments. The alloy conforms to specifications such as ASTM A312, ASTM A358, and ASME SA312, ensuring dimensional accuracy, clean internal surfaces, and consistent wall thickness. These pipes and tubes also demonstrate exceptional resistance to sulphur-bearing atmospheres and cyanide melts, making them a top choice for critical heat applications.

Applications & Industry Use

253 MA Pipes & Tubes are extensively utilized in industries requiring robust thermal resistance and corrosion protection. Typical applications include heat treatment furnaces, waste heat recovery units, radiant tubes, and recuperators. They are also commonly employed in petrochemical processing, cement kilns, incinerators, styrene reactor tubes, and ethylene cracking furnaces. Due to their ability to withstand extreme operating temperatures and harsh chemical exposure, these pipes and tubes are trusted components in power generation, metallurgical operations, pharmaceutical industry and chemical processing plants. Prior to dispatch, every batch undergoes thorough quality checks including radiographic inspection, pitting resistance tests, and mechanical evaluations to ensure compliance with international performance benchmarks.
