Abstract
The invention discloses anti-metal-fatigue austenitic stainless steel. The anti-metal-fatigue austenitic stainless steel is characterized by comprising the following components in percentage by weight: 17%-19% of chromium, 2%-4% of nickel, 0.5%-1.5% of molybdenum, 1.5%-3% of titanium, 0.9%-1.9% of carbon, 1%-1.9% of zinc, 0.1%-0.5% of nitrogen and the balance of iron and impurities. The austenitic stainless steel is capable of resisting metal fatigue.
Description
Technical field
The present invention relates to stainless material field, particularly a kind of austenitic stainless steel of anti-metal fatigue.
Background technology
Austenitic stainless steel, refers to the stainless steel at normal temperatures with austenite structure.As in 304 steel containing Cr about 18%, Ni 8% ~ 10%, C about 0.1% time, there is stable austenite structure.Austenitic chromium nickel stainless steel comprises famous 18Cr-8Ni steel and increases Cr, Ni content on this basis and add the high Cr-Ni Series Steel that the elements such as Mo, Cu, Si, Nb, Ti grow up.Austenitic stainless steel is nonmagnetic and have high tenacity and plasticity, but intensity is lower, and can not make it strengthening by phase transformation, only strengthen by cold working, as added S, the elements such as Ca, Se, Te, then have good free-cutting machinability.
It is generally acknowledged, titanium adds in stainless steel, content lower than 1% time, there is the effect of precipitation strength hardness of steel.
Summary of the invention
The object of this invention is to provide a kind of austenitic stainless steel of anti-metal fatigue.
Technical scheme of the present invention is: a kind of austenitic stainless steel of anti-metal fatigue, is made up of following component:

Anti-metal Fatigue Test
Test event
Metal antifatigue is tested: the austenitic stainless steel that the embodiment 1,2 of cut-off footpath 4mm and comparative example 1 obtain forges the steel wire 5cm obtained, the pulling force of 200N is applied respectively at the two ends of any one point of austenitic stainless steel, then this aluminium alloy wires is bent with the speed of 1 second/time, bending angle is ± 10 °, until fracture, the number of times of record bending.
Test result
The austenitic stainless steel bending number of times of embodiment 1 is 220 times;
The austenitic stainless steel bending number of times of embodiment 2 is 240 times;
