Abstract

For the provision of durable and easily legible inscriptions by jet spraying on steel ingots when they are at an elevated temperature, a nickel or iron metal powder having a largest particle dimension not in excess of 0.075 mm and a zirconium oxide powder or aluminum oxide powder having a largest particle dimension not in excess of 0.075 mm and used in an amount that is not in the excess of 10% by weight of the metal powder are jointly sprayed onto the surface of the steel ingots to form dots or lines thereon.
