Stainless Steel Alloys

Stainless steel centrifugal castings using Johnson Centrifugal Technology are a cost efficient method to produce stainless steel alloys where high yield can reduce expensive machining costs, and are a cost-effective alternative to stainless steel forgings.

Common applications for stainless steel centrifugals include:

  • Medical imaging components: Components for heart and body imaging systems such as CT, PET and MRI.
  • Food processing equipment: Components for separators and centrifuges, mixing and heating systems, and filtration components are produced in 304 and 316 stainless steel, as well as in higher strength alloys such as 17-4ph and Duplex alloys. Centrifugally made Food Industry components also include Cooling Jackets and Water Jackets.
  • Valve components: Butterfly valve housings and discs, balls for ball valves and seal and seat rings are frequently formed in standard 304 or 316 alloys. In highly abrasive applications alloys such as 410, CD4MCu and others can be selected.
  • Power generation components: Seal ring and vane carrier rings are typically formed from stainless steel 17-4ph, 347 or 321.
  • Hydroelectric facilities components: Stainless and bronze are used where high wear resistance and anti-galling are required. Alloys such as 316 and the Nitronic® alloys are often chosen. Turbine seal rings and bearings are also centrifugally cast regularly at JCT.
  • Petrochemical and heat treatment parts: Reducing cones, sleeves and trunnions cones are cast from heat resistant alloys such as HH, HK 40, HP and others in the ASTM A297 family.
  • Custom blended stainless: 20-32Nb, HP and any custom blended stainless needed; one-of-a-kind alloying is commonplace at JCT.

Tight controls of chemistry, foundry process and machining process ensure your requirements are met or exceeded. Computerized spectrographic analysis is used to check every heat lot the JCT produces.
