Product Introduction

253MA stainless steel (UNS S30815) represents a technological breakthrough in heat-resistant austenitic stainless steel in extreme high temperature environments. It solves the industry problem of high-temperature strength and corrosion resistance through the innovative design of nitrogen alloying and rare earth cerium (Ce) microalloying, and becomes an irreplaceable key material in the fields of energy, chemical industry and metallurgy.

S30815 steel pipe Chemical composition

ss253ma High chromium and high silicon

The chromium content (20.0-22.0%) forms a dense Cr₂O₃ oxide film to resist gas corrosion below 1150°C, and silicon (1.4-2.0%) further enhances the antioxidant ability, especially in sulfur-containing atmospheres.

 

253ma stainless steel pipe Nitrogen alloying core

Adding 0.14-0.20% nitrogen significantly improves the high-temperature creep strength through solid solution strengthening while maintaining the stability of the austenite structure.

 

s30815 tube Rare earth cerium microalloying

0.03-0.08% cerium element not only reduces the number of inclusions, but also spheroidizes the residual inclusions, improving the high-temperature ductility and fatigue resistance of the material.

 

Stainless Steel S30815 Pipes Mechanical and Physical Properties

Element SS 253MA
Density 8 g/cm3

UNS S30815 pipe Creep resistance

Under continuous load above 600℃, the creep rupture strength of 253MA exceeds that of 310S stainless steel by more than 2 times. Experiments show that under 700℃/100MPa stress, the second stage of creep of 253MA can last for more than 3000 hours. Its mechanism is:

  • Nitrogen and dislocation interaction
  • Rare earth grain boundary segregation

Material Testing of ss253ma pipe

  • Hardness Test
  • Chemical Analysis – Spectro Analysis
  • Positive Material Identification – PMI Testing
  • Flattening Test
  • Micro and MacroTest
  • Pitting Resistance Test
  • Flaring Test
  • Intergranular Corrosion (IGC) Test

alloy S30815 253 pipe Corrosion resistance

ss253ma pipe Oxidation resistance

In the 1150℃ cyclic oxidation test, the weight gain rate is ≤0.5 g/m²·h, and the oxide scale is dense and firmly attached.

.

stainless steel 253ma pipe Resistance to reducing media

In an H₂S oil and gas environment, the annual corrosion rate is <0.1mm, the tolerance temperature to 70% sulfuric acid is 50℃, which is better than 316L stainless steel.

 

Application of 253ma stainless steel pipe

Oil and gas: submarine pipelines, downhole tools for acid gas wells.

Chemical equipment: sulfuric acid reactors, phosphoric acid evaporators, pickling equipment.

Nuclear industry: containers and pipelines for nuclear waste treatment systems.

Marine engineering: seawater desalination devices, heat exchangers.

Environmental protection: key components of flue gas desulfurization (FGD) systems.
