ASTM A403 254 SMO Reducing Tee Useful info

Alloys 254 / 254 SMO / 6 Mo is an austenitic stainless steel with a high molybdenum content. Coupled with Nickel and Copper this gives the alloy a good resistance to pitting and crevice corrosion, especially in environments containing halide ions, e.g. chloride, bromide and fluoride solutions.

254 SMO (UNS S31254) may offer a cost effective solution to Nickel and Titanium alloys in these environments.

254 SMO is a high-alloy austenitic stainless steel developed for use in seawater and other aggressive chloride-bearing media. The steel is characterized by the following properties:

  • Excellent resistance to pitting and crevice corrosion
  • High resistance to general corrosion
  • High resistance to stress corrosion cracking
  • Higher strength than conventional austenitic stainless steels
  • Good weldability

Standards

  • UNS S31254
  • EN number 1.4547
  • EN name X1CrNiMoCuN20-18-7
  • W.Nr. 1.4529**
  • SS 2378*
  • AFNOR Z1 CNDU 20.18.06AZ*

* Obsolete. Replaced by EN.

** Nearest equivalent grade.

Fabrication

Avoid abrasion against copper/copper alloys or other similar metals which, if present in metallic form, can cause cracks during subsequent welding, hot processing or heat treatment.

Bending

The excellent formability of 254 SMO permits cold bending to very tight bending radii. Annealing is not normally necessary after cold bending.

Corrosion Resistance

  • Excellent resistance to pitting and crevice corrosion due to its high chromium, molybdenum, and nitrogen content
  • Has a very low carbon content, which means there is very little risk of carbide precipitation during heating
  • Possesses very good resistance in water containing chlorides, therefore, it is suitable for use in seawater as it can be exposed to it for prolonged periods without suffering from crevice corrosion

Machinability

  • High work hardening rate combined with a lack of sulfur makes it very difficult to machine
  • Slow speeds, sharp tools, positive feeds, over-powered machine tools, and ample lubrication offer the best results
