Description
Technical field
The invention belongs to metal manufacture field, concretely relates to a kind of stainless steel material.
Technical background
Metal door and window is general all to be made by stainless steel, it is desirable to metal door and window stainless steel need extremely strong antiseptic property and
Unique stainless gloss, heat-insulating property are needed better than same structure ordinary steel, with metal door and window use it is increasingly extensive, to not
The technical requirements of rust steel are also improved constantly, and need which to have enough transverse yield strengths and corrosion resistance；And it is cold at some
Area, stainless low-temperature flexibility be not also high, also can often cause just to rupture at short notice.Therefore how to effectively improve metallic door
Window stainless transverse yield strength, corrosion resistance and low-temperature flexibility are that those skilled in the art have always a demand for solving
Technical problem.
The processing method of traditional stainless steel material typically adopts hot-forging forming means, and which mainly includes step：1st, make material
Embryo；2nd, heat to expecting embryo；3rd, forging forming is carried out to expecting embryo；4th, rest and reorganize and grind；5th, it is heat-treated higher to obtain hardness
Stainless steel instrument.The problem of hot-forging forming mainly comes from the high temperature of its process, causes which to be difficult to precise control of sizes
With the phenomenon such as oxidation, and manufacturing process length, high cost.
Although cold-forge forming can solve the above problems, if stainless steel is not heated, its ductility is poor, enters
And easily cause stainless steel fracture；And as processing hardening is obvious, can mould be caused to damage, its service life can be affected.
The content of the invention
The technical assignment of the present invention is for the deficiencies in the prior art, there is provided a kind of anti-fatigue performance and corrosion resistance and good
Stainless steel material and preparation method.
The technical solution adopted for the present invention to solve the technical problems is：The stainless steel material is consisted of the following composition：
Carbon：0.06-0.09, silicon：0.4-0.6, manganese：1.10-1.40, sulphur：0.01-0.02, chromium：15.0-18.0, magnesium：8.00-8.50,
Nickel：0.40-0.70；Copper：1.7-2.40, neodymium：0.01-0.05, molybdenum：0.1-0.5, nitrogen：0.07-0.12, residual elements 0.01-
0.30, remaining is Fe, and unit is percetage by weight.
The stainless steel material is consisted of the following composition：Carbon：0.08, silicon：0.5, manganese：1.2, sulphur：0.015, chromium：17, magnesium：
8.2, nickel：0.6；Copper：1.9, neodymium：0.03, molybdenum：0.5, nitrogen：0.11, residual elements 0.02, remaining is Fe, and unit is weight percent
Number.
The preparation method of the stainless steel material includes step：
(1) make material embryo；
(2) multiple cold-forge forming passage is carried out to the material embryo, forging embryo is obtained；
(3) rest and reorganization grinding is carried out to the forging embryo；
(4) the forging embryo after grinding of resting and reorganizing is heat-treated.
Compared with prior art, produced beneficial effect is a kind of stainless steel material of the present invention：The present invention's is stainless
Steel material has good fatigue resistance and corrosion resistance；Anti-oxidant, ductility is good；The quality that improve product is decreased
Production cost.
