Abstract

Maraging steel sheet production comprises surface hardening of the maraged sheet at below the martensite to austenite transformation temperature. Production of a sheet of a maraging steel, especially of composition ≤ 0.03% C, ≤ 0.1% Si, ≤ 0.1% Mn, ≤ 0.01% P, ≤ 0.01% S, 0.05-0.15% Al, 17.0-19.0% Ni, 7.0-16.0% Co, 4.0-6.5% Mo, 0.5-2% Ti, optionally one or more of ≤ 0.5% Cr, ≤ 0.5% Cu, ≤ 0.2% Nb, ≤ 0.2% V, ≤ 0.2% Zr and ≤ 0.2% W, balance Fe and impurities, comprises age hardening by heating the sheet, especially after cutting and shaping, to a temperature below the martensite to austenite transformation temperature, the sheet then being additionally surface hardened at below the martensite to austenite transformation temperature. Preferred Features: Surface hardening is carried out by plasma nitriding, hard chromium plating or coating with a hard material.
