Outokumpu typical values apply for the product listed. Cold and hot rolled strip values are generally higher than plate and bar. EN/ASTM values: Mainly for hot rolled plate, transverse direction, from EN 10088, EN 10095, EN 10028-7, ASTM A 240, A 176 and ASME Code Cases. Also values from EN 10269 and ASTM A 473.
EN min. values for cold rolled strip are 10 – 20 MPa higher. Hot rolled strip may on request be certified to the higher level.
Conversion from EN to ASTM, ASME:
1 MPa = 0.1450 ksi 1 J = 0.7376 ft·lbf
°C = 5/9 x (°F – 32) °F = 9/5 °C + 32

Ferritic stainless steels have good corrosion resistance, in particular regarding stres corrosion cracking. Lower carbon and nitrogen contents improve both weldability and toughness which otherwise can be limited.
These stainless steels are characterized by high strength and high wear resistance. Corrosion resistance is limited and weldability degrades with increasing strength, i.e. increasing carbon content.
Duplex stainless steels have high strength, good toughness and very good corrosion resistance, in particular regarding stress corrosion cracking and corrosion fatigue. These steels also have good weldability and reasonable formability.
Good to excellent corrosion resistance combined with very good weldability and formability characterise the austenitic stainless steels. The austenitic structure has good creep resistance and good oxidation resistance that makes them useful at elevated temperatures. Austenitic steel can also be used in cryogenic applications and is, in the annealed condition, the only non-magnetic steel group.
| Schaeffler diagram and microstructures |
The Schaeffler diagram, here a version modified by Outokumpu, is traditionally used to predict delta ferrite content in weld metal from chemical composition. It may also be used to characterise stainless steel microstructures (ferritic, martensitic, austenitic), and to compare the structural balance in similar grades or casts with the same processing history.
One common way to calculate the ferrite number, FNA, is by using the below formulas, where
F = 1.55Si + Cr + Mo + 2Ti + 0.5Nb
A = 30(C + N) + 0.5 Mn + Ni + 0.5(Cu + Co)
FNA = 3.34F – 2.46A – 28.6 for FNA = max. 5.9
FNA = 4.44F – 3.39A – 38.4 for FNA = 6.0 to 11.9
FNA = 4.06F – 3.23A – 32.2 for FNA = min. 12
