Abstract
Plain carbon steel sheet or strip 0.0002 - 0.1 inch thick comprising 0.03 - 0.25% C, 0.20 - 0.60% Mn, 0.05% max. P, 0.034% max. S and balance Fe with residual impurities such as up to 0.014% Si, up to 0.08% Cu, up to 0.018% As and up to 0.03% Ni, is heated to a temperature at least above the A1 critical point to at least partially austenitize the steel, and uniformly quenched, e.g. in water, brine, oil or liquid nitrogen, to obtain a micro-structure consisting at least partially of martensite, so that the product has a tensile strength of at least 90,000 psi and an elongation in 2 inches of at least 1.5%. The cold or hot rolled steel sheet or strip may be heated above the A3 point (1525 - 2100 DEG F.) or between the A1 and A3 point (1330-1670 DEG F.) for partial austenitization, then rapidly quenched e.g. to 35-65 DEG F. preferably at a rate greater than the critical cooling rate to produce a tempered martensite structure; a mixed ferrite and martensite structure is produced on quenching at a rate slower than the critical cooling rate. The sheet or strip product may be subsequently tin plated, galvanized or aluminium coated.
