ISO 21988:2006 defines the grades of abrasion-resistant white cast irons. It specifies the grades in terms of chemical composition and hardness. The types of abrasion-resistant white cast irons covered are unalloyed or low alloy cast irons, nickel-chromium cast irons and high chromium cast irons.
Abstract
Overview
ISO 21988:2006 - Abrasion-resistant cast irons - Classification defines grades of by and . The standard covers three main types: unalloyed or low-alloy cast irons, specific (4% Ni/2% Cr and 9% Cr/5% Ni), and with chromium content ranges from >11% up to 40%. ISO 21988:2006 sets designation rules, order information, manufacturing and heat‑treatment guidance, sampling and testing procedures, and requirements for microstructure and retesting.
