Embodiment Construction

[0046] The specific implementations of the chromium-containing copper-containing ferrite antibacterial and anti-wrinkle stainless steel cold-rolled strip and its manufacturing method will be described in detail below in conjunction with the examples. The specific implementation mode is not limited to the following examples.

[0047] Example 1 of medium chromium copper-containing ferrite antibacterial and anti-wrinkle stainless steel cold-rolled strip

[0048] The composition of this embodiment is (weight %):

[0049] C 0.03 N 0.04 Si 0.60 Mn 0.80 P 0.04

[0050] S ≤0.02 Cr 17.0 Cu 1.30 Ni 1.20 Mo 1.40

[0051] Ti 0.40 Nb 0.30

[0052] The rest is the balance element Fe and unavoidable impurity elements.

[0053] In the cold-rolled stainless steel strips after hot rolling, cold rolling of one rolling process, multiple annealing and pickling, copper-rich precipitates with a particle size of 0.1-0.5 μm are dispersed in the stainless steel matrix and their total area is The r...

Description

technical field [0001] The invention relates to a medium-chromium-copper-containing ferrite antibacterial stainless steel strip and a manufacturing method thereof. Background technique [0002] Medium chromium ferritic stainless steel is a series of grades developed on the basis of AISI430 and 430 to meet the different requirements of steel performance and further alloying. Compared with nickel-based stainless steel, it has excellent performance and low price. Medium-chromium ferritic stainless steel should be used in kitchen equipment, household appliances, transportation, building interior decoration and other fields that require high surface quality of stainless steel. In addition to the common advantages of chromium-based stainless steel, the forming of cold-rolled strip Higher requirements are put forward for the performance, especially the wrinkle resistance of the stainless steel surface during the forming process. Wrinkling is a surface defect of ferritic stainless ...
