X6 CrNiTi 18-10
 
  Oxidizing / neutral.
  Base alloy for low temperatures
1.4828   309 X15 CrNiSi 20-12     Oxidizing / neutral.  
  Alloy for mediun temperatures, no "Sigma" phase
1.4835 2363 S30815   253 MA   Oxidizing / neutral.  Very good mechanical caracterization up to
  1100C and late "Sigma" phase compared to alloys 25/20.
1.4841   314 X15 CrNiSi 25-20      Oxidizing / neutral.
  Good hot characterization
1.4845 2361  310S X8 CrNi 25-21      Oxidizing / neutral
  Good hot characterization
1.4862   330 X8 CrNiSi 38-18 Alloy DS   Carburizing
  Good characterization in carburizing processes
1.4864   330 X12 CrNiSi 36-16 Alloy DS   Carburizing
  Good characterization in carburizing processes
2.4633   N06025 NiCr 25 Fe AlY
 Alloy 602
  Dry oxidizing / neutral / Other.  Very good restance to scaling thanks to
  Al and Y content and high mechanical caracterization
2.4733   N06230 NiCr 22 W 14 Mo Haynes 230
  Vacuum / Oxidizing / N2/H2
  Best mechanical caracterization with temperatures exidinh 1150C
2.4816   N06600 NiCr 15 Fe Alloy 600   Carburizing / Vacuum
  Avoids sticking in Vacuum processes
2.4851   N06601 NiCr 23 FeAl Alloy 601   Oxidixing - presence of S.    Presence of Al improves resistance against
  S and better mechanical caracterization than 2.4816
2.4854   N08020 NiCr 25 FeN Haynes 120   Carburizing
  Good mechanical caracterization up to 1050C
2.4856   N0665 NiCr 22 Mo 9 Nb Alloy 625
  Carburizing / oxidizing
  Resistance to salt corrosion and carburizing
