roidsteel: The worst metal in space.
Roidsteel is spacefarer’s pot metal, refined using crude field techniques from sideritic asteroids. (The term roidsteel derives from the largely nickel-iron composition of such bodies.) The “classic”, if such a term applies, refinement of roidsteel calls for melting the body using a solar mirror, while spinning it to concentrate and rake off stony slag, and finally forming it into ingots or sheets by thrust-forging. In practice, the production method varies widely, since roidsteel is a staple of field repairs carried out with inadequate equipment.
The properties of roidsteel cannot be given exactly, since the composition of each sideritic asteroid differs, and the production of roidsteel rarely makes any attempt to control its composition beyond basically nickel-iron; substantial quantities of various impurities – often valuable metals in their own right – are always present. Thus unreliable, the accepted uses of roidsteel are cobbling together an emergency hull patch, armor plate, or spar to enable one to limp to a nearby cageworks, at which point the roidsteel can be sold at average-density value to a refiner and a proper repair be implemented.
Should someone attempt to sell you goods made from roidsteel, take your leave and don’t look back.

The logical next step is to make a Hariven entirely out of roidsteel.
When life gives you roidsteel, make Harivens?
