0.05C Low Carbon Steel (var. 2)

This is a low-carbon iron-nickel-silicon alloy with trace additions of refractory and transition metals (V, Mo, Nb, Cr, Co), designed to balance strength and ductility while maintaining ferriticity. The composition—dominated by ~16.6% Ni and ~5% Si with minimal carbon—suggests a material engineered for corrosion resistance, thermal stability, or controlled phase behavior in demanding environments, likely representing a specialized research or niche industrial variant rather than a commodity steel grade.
