- (rare) To convert iron into steel, or to coat with a layer of steel by converting only the surface of the iron.
- The success of an attempt to acierate iron will depend on the amount of nitrogen contained by the iron during carburation.
- As an economy measure, the manufacturer decided to use iron rather than steel, but to acierate the surface to limit oxidation.
- 1861 June 22, M. Fremy, “On the Chemical Composition of Cast Iron and Steel”, in The Chemical News and Journal of Industrial Science, volume 3, page 375:
- The effect of manganese, whose influence on acieration is known to all manufacturers, is probably due to its rapid oxidation, thus producing a metallic oxide capable of completing the fining of the iron, and this, by eliminating any foreign body, facilitates the acierating process.

- It was noted by Biringuccio in 1540, and described by Agricola in "De Re Metallica" 1561 — that a bar of wrought iron, kept immersed long in molten cast iron, became acierated by taking up the carbon of the cast iron.

- Activities: Production of stone crushers (capacity from 0.3 to 2.5 metric tonnes a batch), blasting machines (compression capacity of 160 tonnes), and steel-acierating machines.
