ASTM A403 254 SMO Reducer Specification

Standards:

  • ASTM/ASME: UNS S31254
  • EURONORM: FeMi35Cr20Cu4Mo2
  • DIN: 2.4660

Product Name: ASTM A403 254 SMO Reducer

254 SMO

UNS S31254 F44/ 1.4547 / 2378

reducers eccentric

The wide range of Reducers offered by us is available in two different forms, one is concentric and another is eccentric types. These are developed using quality steel and other alloys and find usage in sugar mills & distilleries, pumps & petrochemicals cement & construction industries and steel plants. Our ASTM A403 254 SMO Reducer range is available in various sizes, schedules and flange configurations as per the requirements of the clients. The ASTM A403 254 SMO Reducer offered by us have inlet and outlet ends and they align to a common center line.

Function of both types of reducer is to reduce the line from a larger to a smaller pipe size, this obviously results in an increased flow pressure. With the eccentric reducer the smaller outlet end is off centre to the larger end enabling it to line up with one side of the inlet and with the other.

The concentric reducer is so manufactured that both inlet and outlet ends are on a common centre line. The concentric type is easier and less expensive to produce but does not allow quite the same versatility as the eccentric reducer. The lengths of both types are fixed by manufacturing standards.

We offer the international quality pipe reducers made up of steel and other alloys. Steel Pipe Reducers available are of concentric and eccentric types. The pipe reducers are suitable components in pipelines that reduce pipe size from large to small bores. The inlet and outlet ends of the steel pipe reducers and alloy pipe reducers align to a common center line.

ASTM A403 254 SMO Reducer 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

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
