Characteristic |
DSH400F |
Hardness is higher than SUS303.
Permeability at Hv400 is μ≦1.01, and it is machinable.
Corrosion resistance is equivalent to SUS303. |
DSN6 |
Hardness Hv500 is achieved by cold working. Hardness becomes higher by precipitation hardening treatment.
Permeability at Hv480〜500 is μ≦1.01.
Corrosion resistance is better than SUS304. |
DSN9 |
Proof strength is almost equivalent to duplex stainless steel (SUS329J1). It is available in the sea due to excellent seawater resistance. Hardness Hv500 is achieved by cold working. Hardness becomes higher by precipitation hardening treatment.
Even 80% of cold working, permeability is low at μ≦1.01.
Heat resistance is equivalent to SUH660, better than SUS310. |
