Abstract

The invention discloses a corrosion-resistant metal material and a production process thereof. The corrosion-resistant metal material comprises the following components in percentage by weight: 1-5% of carbon, 0.01-0.08% of silicon, 0.02-0.08% of manganese, 1.2-3% of nickel, 0.06-0.12% of zirconium, 0.02-0.23% of antimony, 0.12-0.18% of tin, and the balance of iron and inevitable impurities; the production process of the metal material comprises the following steps: melting in an electric furnace: fully and uniformly mixing the metal element components, refining in a converter, performing casting molding, carrying out heat treatment and tempering. According to the corrosion-resistant metal material and the production process thereof, the various metal elements and rare earth elements are added, the electrical conductivity and thermal conductivity are improved, the hardening capacity is reduced, the mechanical property is excellent, and therefore the corrosion-resistant metal material is suitable for kitchen or operating room knives.

Description

technical field [0001] The invention relates to the technical field of metal materials, in particular to a corrosion-resistant metal material and a production process thereof. Background technique [0002] Alloys are substances with metallic properties that are synthesized by two or more metals and metals or nonmetals by a certain method. It is generally obtained by melting into a homogeneous liquid and solidifying. According to the number of constituent elements, it can be divided into binary alloys, ternary alloys and multi-element alloys. Corrosion-resistant basic alloying elements include nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., to meet the requirements of various uses for corrosion-resistant structures and properties. Alloy materials are easily corroded by chloride ions, because chromium, nickel, and chlorine are isotopic elements, and isotopic elements will be exchanged and assimilated to form corrosion of stainless steel. However, conventional...
