Document Type and Number:
Japanese Patent JPH0753917
Kind Code:
B2
Abstract:
The invention provides a composition for addition to water to provide an aqueous solution that is effective for use in the physico-chemical refinement of magnetic stainless steel surfaces said composition comprising, in a major amount, an acid ingredient consisting at least predominantly of oxalic acid and, in a minor amount, an accelerating ingredient consisting essentially of a sulfur-containing compound such as a thiocyanate salt; and a nitrobenzene compound oxidising agent such as m-nitrobenzene sulfonic acid, said composition being at least substantially completely soluble in water at 20 DEG Centrigrade, in amounts of said composition of up to 10 percent by weight of water. Advantageously the compositions can contain a hydroxyalkylamine surfactant containing 2 to 4 carbon atoms and a poly(oxyethylene)alkyl alcohol surfactant. Also provided are solutions containing the said compositions and processes for refining magnetic stainless steel surfaces using such solutions.
