Alloy 254SMO

UNS S31254

Description

Trust Us as Your Alloy 254 SMO Pipe Distributor

You want a reliable alloy for your pipe products. Come to James Duva Inc., where we provide durable 254 SMO stainless steel products. We include high contents of molybdenum, nitrogen, and chromium when making 254 SMO, which makes it perfect for high chloride environments. In fact, 254 SMO exceeds Alloy 825, Alloy 20, and Alloy 904L in chloride resistance.

This alloy is also compatible with other common austenitic stainless steels, which makes it ideal as a replacement. In cases where Type 317L or 316L fails from chloride stress, pitting, or crevice attacks, try 254 SMO. Not only is this alloy more technically adequate, but it is also a more affordable replacement for titanium and nickel-based alloys.

Typical Applications

If you’re unsure if 254SMO will fit your company application needs, check out these common applications:

  • Brackish water
  • Chemical processing equipment
  • High chloride process streams
  • Food processing equipment
  • Gas and oil production equipment
  • Pulp mill bleach plants
  • Desalination equipment
  • Tall oil distillation columns and equipment
  • Seawater handling equipment

Design Features

254 SMO is stronger than other common austenitic stainless steel grades. It also has high ductility and impact strength. Here are some other benefits from using 254 SMO.

  • High resistance to general corrosion, crevice, pitting, and chloride stress
  • Strength greater than 300-series austenitic steels by 50%
  • Endurance against intense impacts
  • Workability and weldability

Availability

  • Weld Pipe  3/4” – 24”
  • Butt-Weld Fittings 3/4” – 24”
  • Flanges 3/4″ – 24”
  • Bar 1″ – 8″

Specifications

  • ASTM A312, A403, A182
  • ASME SA312, SA403, SA182

Tensile Requirements

254SMO has incredible strength, including 94 (KSI) tensile strength and 44 (KSI) yield strength. You can transform the KSI measurements to Megapascal (MP) measurements by multiplying the KSI by 6.895.
