Abstract

The invention discloses an anti-vibration W-In-containing stainless steel kettle material for hot dip aluminum plating. The anti-vibration W-In-containing stainless steel kettle material comprises, byweight, 0.3-0.5 wt.% of Rb, 0.5-0.8 wt.% of W, 6.0-8.0 wt.% of Cr, 5.0-6.0 wt.% of Al, 1.5-3.0 wt.% of Co, 1.0-1.5 wt.% of In, 0.1-0.2 wt.% of S, and the balance Fe. According to the anti-vibration W-In-containing stainless steel kettle material for hot dip aluminum plating, the current situation that at present, technologies of materials for iron kettles in the hot dip aluminum plating field inChina is changed, through innovation and optimization of the material science, the development bottleneck of the production technology and equipment for hot dip aluminum plating steel plates in the high-end field in China is broken through, and in the near future, the iron kettle material is widely applied to the greatest extent.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to an iron alloy. Background technique [0002] Metal materials are damaged by the physical and chemical action of the surrounding medium, which is called metal corrosion. Metal rusting is the most common form of corrosion. During corrosion, a chemical or electrochemical heterogeneous reaction occurs at the interface of the metal, which turns the metal into an oxidized (ionic) state. This will significantly reduce the mechanical properties of metal materials such as strength, plasticity, and toughness, destroy the geometry of metal components, increase wear between parts, deteriorate electrical and optical physical properties, shorten the service life of equipment, and even cause disasters such as fire and explosion. sex accident. According to statistics, the annual loss of steel due to metal corrosion accounts for about 10-20% of the steel output of the year. The indirect losses ...
