C (carbon) is the same with N (nitrogen), is the stabilizing element of effective austenite phase, and is the element that helps to improve elastic properties, and therefore the lower limit of C (carbon) content being formulated is 0.01%.Yet, C (carbon) is the element that causes erosion resistance to reduce, if sosoloid C (carbon) excessively occurs, because the sclerosis that increase caused that C (carbon) measures in the sosoloid has just destroyed stainless workability, consider that therefore it is 0.15% that this factor is formulated the upper limit of C (carbon) content so.
Si (silicon) is used to obtain high-intensity effective element, and therefore best, Si (silicon) content is at least 0.1%.Yet because Si (silicon) content has increased, permeability can significantly increase after cold working, and so just becoming to keep non magnetic, and therefore the upper limit of Si (silicon) content being formulated is 5%.
Mn (manganese) is the same with Ni (nickel), is the stabilizing element of austenite phase, therefore suppresses the increase of permeability in cold working.And Mn (manganese) is the element that increases the solid solubility of N (nitrogen).In order to demonstrate these abilities, Mn (manganese) content is necessary at least 1%, and must regulate Mn (manganese) content together along with Ni (nickel) content, so that keep non magnetic after cold working; Yet, if comprise Mn (manganese), can not see suitable with it effect so more than 10%, therefore the upper limit with Mn (manganese) content is set at 10%.
Ni (nickel) is the basal component of austenitic stainless steel, and is the effective element that helps austenite mutually stable.In order to keep non magnetic after cold working, Ni (nickel) content is necessary at least 8%, and must regulate Ni (nickel) content together along with Mn (manganese) content relevant with Si (silicon) content.Yet, can cause reduction on the elastic properties at Ni after the cold working (nickel), therefore the upper limit of Ni (nickel) content being formulated is 25%.
Cr (chromium) is stainless basal component, and in order to obtain splendid anti-corruption (erosion) property, Cr (chromium) content is necessary at least 14%; Yet, if comprise a large amount of Cr (chromium), will produce a large amount of delta ferrites so, therefore can not guarantee non magnetic; Therefore the upper limit of Cr (chromium) content being formulated is 30%.
N (nitrogen) helps to keep nonmagnetic element, and the stainless principal character of described non magnetic the present invention of being also is used to improve intensity and obtains splendid elastic properties; Therefore, the lower limit of N (nitrogen) content being formulated is 0.01%.Yet, if N (nitrogen) content has surpassed 0.25%, so as C (carbon), because the sclerosis that increase caused of N (nitrogen) amount will destroy stainless workability in the sosoloid.And will destroy its castability, therefore can not obtain firm (sound) steel ingot bar; Therefore the upper limit of N (nitrogen) content being formulated is 0.25%.Usually, in the situation of workability (for example fixed in shape), require therefore must make stainless steel softer, therefore preferably the upper limit of N (nitrogen) content is formulated to being lower than 0.06% making the work-ing life of punching die longly.
Cu (copper) is the stabilizing element of austenite phase, and is the effective element that is used to give workability.In order to demonstrate this effect, preferably add at least 0.5% Cu (copper).Yet if added Cu (copper) more than 3%, a kind of so so excessive interpolation that has surpassed the Cu (copper) of solid solubility limit will weaken workability, and therefore the upper limit of Cu (copper) content being formulated is 3%.
Nb (niobium), W (tungsten) and V (vanadium) are the elements that increases work hardening capacity, and in order to demonstrate this effect, preferably add total amount and are at least 0.05% Nb (niobium), W (tungsten) and V (vanadium).Yet, if added a large amount of Nb (niobium), W (tungsten) and V (vanadium), will occur the loss in the hot workability so, and will produce delta ferrite, therefore can not keep non magnetic; Therefore the upper limit formulation with the total content of Nb (niobium), W (tungsten) and V (vanadium) is 0.5%.
Mo (molybdenum) is the element that helps to improve erosion resistance, and in order to demonstrate this effect, preferably adding is at least 0.1% Mo (molybdenum).Yet, if added a large amount of Mo (molybdenum), will increase the generation of delta ferrite so, therefore can not keep non magnetic; Therefore the upper limit of Mo (molybdenum) content being formulated is 2%.
In addition, must on stainless steel of the present invention, give machine tensions also by cold working work hardening stainless steel in order to obtain high strength.Therefore the cold working corresponding to from 30% to 80% cold-rolled compression ratio is necessary.Although carry out such cold working, in order to ensure non magnetic, Ni (nickel) equivalent value of describing defined as the front must be at least 19.The cold-rolled compression ratio is called as material at the variation of the sheet gauge under the cold rolling situation and the per-cent between the initial sheet gauge.Yet, will reduce the work hardening capacity of steel if the content of Ni (nickel) and Mn (manganese) is too high so to improve Ni (nickel) equivalent value, so the content of Ni (nickel) and Mn (manganese) must be as the defined of front.
In addition, producing the integral part of stainless steel of the present invention with thereon slide fastener etc. by having as the cold rolling of at least 60% cold-rolled compression ratio of above-mentioned qualification, is necessary for the performance that keeps broken needle to detect after having carried out 60% cold-rolled compression therefore.As mentioned above, for stainless steel of the present invention, in order to obtain high strength, 30% to 80% cold-rolled compression ratio is necessary, is necessary for the performance that keeps broken needle to detect later at the cold-rolled compression that carries out at least 30% therefore; Depend on finished product or the parts produced, must act on 60% cold-rolled compression, therefore normally preferred for the performance that keeps broken needle to detect after having acted on 60% cold-rolled compression.
