Description

A kind of steel and preparation method thereof
Technical field
The present invention relates to mechanical material field, be specifically related to a kind of steel and preparation method thereof.
Background technology
Steel are that steel ingot, steel billet or steel make required variously-shaped, size and the material of performance by pressure processing Material.Steel are widely used, various in style, according to the difference of section configuration, steel are generally divided into section bar, sheet material, tubing and metal The big class of goods four.Different according to steel processing temperature, cold working and hot-working two kinds can be divided into.
Steel material can run into some special environment in commercial Application, as molten in run into strong acid solution, strong base solution, salt The erosion of liquid etc., these solution create the biggest impact to outward appearance and the performance of steel material.Prolongation over time, corrodes Phenomenon is more serious, causes cannot normally using of Steel material.Therefore, improve the decay resistance of steel, steel can not only be extended In the service life of material, more can widen the range of steel.
Summary of the invention
In sum, in order to overcome the deficiencies in the prior art, the technical problem to be solved is to provide a kind of steel Material and preparation method thereof.
The technical scheme is that a kind of steel, by the raw material system of following parts by weight Become: carbon 3-6 part, nitrogen element 1-3 part, phosphide element 4-7 part, element silicon 2-5 part, P elements 1-3 part, boron element 2-5 part, nickel Element 3-5 part, manganese element 1-3 part and wolfram element 2-5 part.
Further, the chromium element that parts by weight are 2-5 part is also included.
Further, the lead element that parts by weight are 1-3 part is also included.
The preparation method of a kind of steel, is prepared by the steps:
(1) raw material of following parts by weight is weighed respectively: carbon 3-6 part, nitrogen element 1-3 part, phosphide element 4-7 part, silicon Element 2-5 part, P elements 1-3 part, boron element 2-5 part, nickel element 3-5 part, manganese element 1-3 part, wolfram element 2-5 part, chromium element 2-5 part and lead element 1-3 part；
(2) the raw material continuous casting process weighing step (1) is founded and is obtained slab；
(3) it is heated to slab implement hot rolling for the first time；
(4) slab is lowered the temperature；
(5) slab is heated 700-800 DEG C to implementing second time hot rolling.
Further, in step (3), the temperature of hot rolling for the first time is 800-900 DEG C.
Further, slab is cooled to 700 DEG C by step (4).
Further, in step (5), the temperature of second time hot rolling is 700-800 DEG C.
The invention has the beneficial effects as follows: each raw material components proportioning of these steel is scientific and reasonable, the steel stability made Preferably, corrosion resistance and wear resistance are good, have good percentage elongation, substantially prolongs service life.
