PRODUCTS & QUALITY
Iron to your spec. Shipping from Houston.
High-purity iron and primary iron units, made in one furnace and verified in our own lab before they ship. For specialty alloys, magnets, forgings and EAF steelmaking. Trial quantities available now.
HEAT 01
Where clean iron goes.
From AI data centers to jet engines, it starts with clean iron.
- High-purity iron
Specialty alloys and superalloys
Clean, low-residual charge iron for vacuum induction melting (VIM) of superalloys and specialty steels.
- High-purity iron
Rare earth magnets
NdFeB magnets are about 70% iron. Domestic high-purity iron for EV motors, wind, drones and defense.
- Steel-grade iron
Data centers and the grid
AI runs on power. The transformers and cooling motors behind it depend on electrical steel and magnets, and both start with clean iron.
- High-purity iron
Aerospace and defense forgings
Consistent, clean iron units for forging-quality and defense steels.
- Steel-grade iron
Powder and additive manufacturing
Low-impurity iron feedstock for powder metallurgy and 3D-printed parts.
- Steel-grade iron
Advanced steelmaking
Low-residual primary iron units for EAF melt shops making advanced grades.
- In development
Electrical steel
Low-residual iron is where electrical steel starts. Our furnace makes the clean chemistry these grades need. Partner with us on development.
HEAT 02
Two grades, and everything in between.
These are our standard grades. The same furnace can be tuned to the purity, chemistry and form you need. Looking for something else? Send us your spec.

Product 01 · For specialty alloys and magnets
High-purity iron
High-purity iron for vacuum induction melting (VIM) of specialty alloys and superalloys, and for NdFeB magnets. Most of the world’s high-purity iron comes from a single country. Hertha gives U.S. buyers an independent, domestic source.

Grade SG · EAF
● Trial heats available
EAF-ready
Typical values are for reference, not a mill certificate. Every shipment is certified against the buyer's specification.
HEAT 03
Your spec. Verified before tap.
01
You set the spec
Target chemistry and impurity limits, down to parts per million.
02
Tuned while it runs
The furnace runs continuously, so chemistry is adjusted during the campaign, not between heats
03
Checked before tap
Bath samples run on OES and LECO confirm the metal meets spec while it’s still in the furnace.
04
Certified as delivered
