Abstract
The invention relates to the technical field of a novel material, especially to the technical field of novel austenitic stainless steel. Novel austenitic stainless steel provided by the invention comprises the following elements: carbon (C) 0.8 to 1.5%, chromium (Cr) 15 to 22%, manganese (Mn) 8 to 18%, nickel (Ni) 1.0 to 2.5%, nitrogen (N) 0.18 to 0.65%, phosphorus (P) < 0.045% and sulfur (S) < 0.01%. A preparation formula for the novel austenitic stainless steel provided by the invention overcomes the problem that the wear resistance degree of conventional stainless steel does not catch up with formula cost and realizes preparation of novel austenitic stainless steel with a higher wear resistance degree at little expense.
Description
The present invention relates to a kind of new material technology field, particularly novel austenite stainless steel technical field.
Background technology
Austenitic stainless steel is to use now a kind of stainless steel widely, and it has good corrodibility, thermotolerance, low temperature intensity and mechanical property.Be widely used in household supplies, auto parts machinery, medical apparatus, building materials, chemical industry, foodstuffs industry, agricultural, ship components etc.But current austenitic stainless steel exists the problem that rub proofness does not chase after formulation cost, that is to say, improve stainless wear resistance, cost need to increase fasterly, thereby has lost using value.In widely used austenitic stainless steel, the content of nickel is higher now, is that the nickel resources of 8% ~ 10%，Er China is deficient, cause this type of stainless steel expensive, and the price of nickel is also rising steadily in recent years, rise speed, causes this type of austenitic stainless steel cost constantly to increase.
Summary of the invention
The invention provides novel austenite stainless steel, utilize chromium, manganese, carbon, the nitrogen of relative low price to replace molybdenum, nickel and the titanium that price is comparatively expensive, meet the requirement that utilizes less cost to exchange more wear resistance for, solved the problem of traditional austenitic stainless steel cost costliness.
The present invention is achieved through the following technical solutions: novel austenite stainless steel, comprising: carbon, chromium, manganese, nickel, nitrogen phosphate and sulfur.It is characterized in that the element that contains following weight percent, carbon (C): 0.8-2%; Chromium (Cr): 15-22.5%; Manganese (Mn): 8-18.5%; Nitrogen (N): 0.18-1%, described rest part is comprised of Fe and inevitable impurity.
As preferably, the element that austenitic stainless steel of the present invention contains following weight percent, carbon (C): 0.8-1.5%; Chromium (Cr): 15-22%; Manganese (Mn): 8-18%; Nitrogen (N): 0.18-0.65%, described rest part is comprised of Fe and inevitable impurity.
In austenitic stainless steel of the present invention, inevitably impurity comprises nickel (Ni), phosphorus (P), sulphur (S).It allows the weight percent content using to be: nickel (Ni): 1.0-2.5%; Phosphorus (P) < 0.045%; Sulphur (S) < 0.01%.
Beneficial effect of the present invention:
1, the present invention uses chromium, manganese, carbon, the nitrogen of relative low price, substitutes molybdenum, nickel and titanium, has reduced the production cost of traditional austenitic stainless steel.
2, the present invention is increased to carbon content the twice left and right of carbon content in original formula, and the content of manganese is suitable with the content of original chromium, and the content of chromium is equivalent to the content of molybdenum in original formula, and nitrogen substitutes nickel and the titanium in original formula; The content of nickel only retains 1 ~ 2.5%, has solved the problem that rub proofness does not chase after formulation cost, has met and has utilized less cost to exchange the requirement of more wear resistance for.
Embodiment
The present invention includes: carbon, chromium, manganese, nickel, nitrogen phosphate and sulfur.It is characterized in that the element that contains following weight percent, carbon (C): 0.8-2%; Chromium (Cr): 15-22.5%; Manganese (Mn): 8-18.5%; Nitrogen (N): 0.18-1%, described rest part is comprised of Fe and inevitable impurity.
As preferably, the element that austenitic stainless steel of the present invention contains following weight percent, carbon (C): 0.8-1.5%; Chromium (Cr): 15-22%; Manganese (Mn): 8-18%; Nitrogen (N): 0.18-0.65%, described rest part is comprised of Fe and inevitable impurity.
In austenitic stainless steel of the present invention, inevitably impurity comprises nickel (Ni), phosphorus (P), sulphur (S).It allows the weight percent content using to be: nickel (Ni): 1.0-2.5%; Phosphorus (P) < 0.045%; Sulphur (S) < 0.01%.
The present invention describes by specific implementation process, without departing from the present invention, can also carry out various conversion and be equal to replacement invention, therefore, the present invention is not limited to disclosed specific implementation process, and should comprise the whole embodiments that fall within the scope of the claims in the present invention.
