    1.4021

    1.4021 (AISI 420) is used in the quenched and tempered condition in a host of constructional and fastener applications where moderate corrosion resistance is required. The knife blade variant of 1.4021 can be polished to high gloss finishes. Optimal corrosion resistance is also attained when the surface is finely ground or polished.
