Table 6. Compositions and mechanical properties of the cast steel compared with wrought steel in literature.

Nickel-free austenitic stainless steels for medical applications

“…Currently, high-nitrogen steels are usually produced by pressured electroslag remelting, counter-pressure casting, plasma arc melting and powder metallurgy [74][75][76]. In the development and production of high-nitrogen nickel-free stainless steels, Mn is also added to further enhance the nitrogen content; Mn is also a nickel substituting alloy element.…”

Some Theoretical Aspects on Designing Nickel Free High Nitrogen Austenitic Stainless Steels.

“…If S and O are to be removed subsequently simple ESR processing as done by Balachandran et al would be adequate. 22) Nitrogen solubility is reported to be more in arc melting compared to induction melting due to N getting absorbed in the arc plasma. 15) Nitrogen alloying in commercial processes is carried out predominantly with the use of additions of nitrided ferro-alloys to the molten metal bath such as in Pressure ESR, 23) air induction melting, 24) and Electric arc furnace.…”

Influences of the Transverse Static Magnetic Field on the Droplet Evolution Behaviors during the Low Frequency Electroslag Remelting Process

“…To settle the problem of nonmetallic inclusions damaging the mechanical properties of steels, electroslag remelting (ESR) technology [1][2][3][4][5][6] was developed for its excellent purification efficiency. Nowadays, the ESR process has become more and more important for the increasingly high requirements of the steels in areas such as electricity, aviation, metallurgy, machinery and so on.…”
