Embodiment Construction

[0024] The specific embodiments of the ferritic antibacterial stainless steel for low-chromium copper-containing tableware and the manufacturing method thereof will be described in detail below with reference to the examples, but the specific embodiments of the ferritic antibacterial stainless steel for low-chromium copper-containing tableware and the manufacturing method thereof are not limited. in the following examples.

[0025] Example 1 of ferritic antibacterial stainless steel for low-chromium copper-containing tableware

[0026] The components (wt%) of this example are:

[0027] C 0.015 Si 0.30 Mn 0.51 Cr 13.15 Ni 0.030

[0028] Cu 2.05 N 0.015 Nb 0.250 The rest are Fe and inevitable impurities.

[0029] After the hot-rolled annealing and cold-rolled annealing of the ferritic antibacterial stainless steel for low-chromium copper-containing tableware in this embodiment, copper-rich precipitates with a particle size of 0.1-0.5 μm are dispersed in the matrix and the surfac...

Abstract

Disclosed is a ferrite antibacterial stainless steel for low-chrome copper-containing dishware and manufacturing method, wherein the stainless steel matrix comprises (by wt%) Cr 12.0-14.0%, Cu 0.70-2.20%, C <=0.08-0.15, the preparing process comprises pre-processing melted iron, passing through composite revolving furnace, vacuum oxygen decarbonization furnace, refined-smelting ladle furnace, continuous plate blank casting, casting blank annealing, tandem rolling, and annealing in a bell-type furnace.

Description

technical field [0001] The invention relates to a ferritic antibacterial stainless steel for low-chromium copper-containing tableware and a manufacturing method thereof. Background technique [0002] With the development of the economy and the improvement of people's living standards, people's health awareness is gradually strengthened, and they pay more attention to the living environment and quality of life. There are stricter requirements for kitchen utensils that are directly related to human food hygiene and safety. After experiencing "SARS" and "bird flu", the domestic market demand for antibacterial materials and antibacterial products has rapidly increased, and consumers have begun to recognize and accept "antibacterial" products. Due to the good rigidity, corrosion resistance, rust resistance and beautiful appearance quality of stainless steel, stainless steel has been widely used in the food industry, catering service industry and family life. Will have broad mar...
