Abstract

The invention discloses a corrosion-resistant stainless steel kettle material used for zinc-aluminum alloy hot dipping and a processing process thereof. An alloy includes 1.0 wt.%-1.2 wt.% of Li, 0.2wt.%-0.3 wt.% of Mo, 0.1 wt.%-0.2 wt.% of Ca, 8.0 wt.%-9.5 wt.% of Cr, 6.2 wt.%-7.5 wt.% of Ni, 4.0 wt.%-8.0 wt.% of Si, 1.5 wt.%-1.8 wt.% of Co, 0.2 wt.%-0.5 wt.% of B and the balance iron. By meansof development and industrialization of the material, a solution of material science is provided for the current situation that an existing iron kettle in hot-dip galvanizing zinc-aluminum alloy production is extremely short in service life and reloading is not convenient. Implementation and industrialization of the material have important significance in solving the current industry situation ofChina and improving the international competitiveness of products of the metallurgical industry in China.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to a zinc alloy. Background technique [0002] The ocean covers about 71% of the earth's surface, and the marine industry has become an important pillar of the world's economic development. The salt concentration in seawater is high, oxygen-rich, and there are a large number of marine microorganisms and macrobiotics. Coupled with the impact of waves and sunlight, the marine corrosion environment is relatively harsh. Corrosion in the marine environment has become the most important factor affecting the safety, service life and reliability of facilities, and has attracted great attention from governments and industries around the world. [0003] After the steel is galvanized, the corrosion resistance is greatly improved, which can save materials and resources, and exert better economic and environmental benefits. During the use of steel, the coating is partially damaged, and the expo...
