Families
| Family | Grades | Nickel | Key alloying elements | HS heading |
|---|---|---|---|---|
| Duplex and 254 SMO stainless scrap | 5 | 6–38% | Cr, Mo | 7204.21 |
| Ni-Resist scrap | 3 | 16–35% | Cu, Cr, Si | 7204.10 |

Why They Are Kept Separate
| Material | Base metal | Density, g/cm³ | Quick check |
|---|---|---|---|
| Titanium | Titanium | 4.4–4.5 | Light for its size; XRF shows Ti |
| Duplex stainless | Iron | 7.8 | Magnetic; XRF shows Fe base |
| 254 SMO | Iron | 8.0 | Non-magnetic; 6% Mo, 18% Ni |
| Ni-Resist | Iron (cast) | 7.3–7.6 | Castings; OES shows carbon |

Mipra Steel imports and buys exotic alloy scrap in India and exports it: see exotic alloy scrap importer and buyer and exotic alloy scrap exporter from India. Lots are sorted and prepared before dispatch: how we sort and prepare scrap lots. Much of what we buy comes from South India, and our head office is in Khetwadi, Mumbai.

FAQ
Why keep exotic alloys apart from nickel alloy scrap?
Each has its own melting route, HS heading and value drivers. Mixing titanium, duplex or Ni-Resist into a nickel alloy lot lowers the value of both.
Does Mipra Steel buy titanium and tungsten carbide scrap?
Yes. Titanium, tungsten carbide, duplex, 254 SMO and Ni-Resist scrap are all bought, each as its own lot and apart from nickel alloys.
Is duplex stainless steel a nickel alloy?
No. Duplex and super-austenitic grades are iron-base stainless steels with about 5 to 18% nickel, so their scrap is sold apart from nickel alloy scrap.
Does Mipra Steel buy exotic alloy scrap in India?
Yes. Mipra Steel buys exotic and special alloy scrap from sellers across India, much of it from South India.
