Morphology
oil-hardened + steel
The noun phrase is transparently compositional: it denotes steel that has been hardened by oil, combining 'oil' with 'hardened' (the past-participle adjective of 'harden'). Although the term is somewhat technical, the modifier–noun pattern and meanings of the constituents allow a B1 learner who knows the words to infer the overall meaning.
Etymology
The compound noun oil-hardened steel comes from a simple metal-making process: hot steel is cooled quickly in oil, which makes the metal hard. So, oil-hardened steel means steel that has been 'hardened' by oil to give extra strength for tools and blades.
