Embodiment Construction
[0014] Below in conjunction with embodiment the present invention will be further described.
[0015] Table 1 is the chemical composition of the stainless steel pipes and fittings of Examples 1-4, and Table 2 is the test results of sterilization, mechanical properties and corrosion resistance of the stainless steel pipes and fittings of Examples 1-4.
[0016] The preparation method of Examples 1-4 of the present invention is as follows: the corresponding raw materials are mixed and smelted to make a stainless steel blank, and then solidified at 1050°C for 0.5h, then rapidly cooled to room temperature, and then heated to 700°C for 6h. , slowly cooled to room temperature.

Abstract
The invention belongs to the technical field of stainless steel materials, and particularly relates to a thin-walled antibacterial stainless steel product and a preparation method thereof. Chemical components of the thin-walled antibacterial stainless steel product comprise, by mass percent, not larger than 0.08% of C, not larger than 0.75% of Si, not larger than 2.0% of Mn, not larger than 0.04%of P, not larger than 0.03% of S, 8.0%-14.0% of Ni, 16.0%-20.0% of Cr, 3.5%-4.5% of antibacterial metal elements and the balance Fe and inevitable impurities. The preparation method comprises the steps that after raw materials are mixed and smelted, a stainless steel primary blank is made, and then solid solution heat treatment is carried out. The antibacterial metal elements are added in stainless steel, so that the antibacterial metal elements are evenly and dispersedly separated out in a stainless steel matrix with a certain size and form, and excellent antibacterial performance is given tothe stainless steel under the condition that the mechanical property and corrosion resistance of common stainless steel are not reduced.
