Abstract
The invention discloses steel capable of being effectively prevented from being corroded. The steel comprises, by weight, 0.04% to 0.17% of carbon, 0.33% to 0.4% of silicon, 0.02% of phosphorus or less, 0.02% of nickel or less, 1.36% of chromium or less, 0.25% to 0.95% of molybdenum, 0.015% of vanadium or less and the balance iron and impurities. A steelmaking process of the steel comprises the steps that after a bloom slab is heated, the bloom slab is rolled into a steel strip, and the steel strip is cooled and rolled into a steel roll. In this way, according to the steel capable of being effectively prevented from being corroded, the surface of the steel is prevented from being corroded or rusting, the service life of a steel product can be effectively prolonged, the surface of the steel is still as bright and clean as new steel after long-time use, attractiveness is not influenced, and use is not influenced.
Description
Technical field
The present invention relates to Steel material field, particularly relating to one can effective etch-proof steel.
Background technology
Steel be with ferrum as essential element, phosphorus content typically below 2%, and containing the material of other elements.Steel can be carried out heat treatment process use.Heat-Treatment of Steel is divided into bulk heat treatmet, Surface heat-treatent and thermo-chemical treatment according to process, bulk heat treatmet refer to annealing, normalizing, quench, technique, the Surface heat-treatent such as tempering are surface hardening by flame heating, induced surface hardening, LASER HEATING surface hardening etc., thermo-chemical treatment is carburizing, nitriding, oozes other element etc..Existing steel gets rusty easily, and can produce one layer of rust on surface, not only affect attractive in appearance, also can affect use after long-time use.
Summary of the invention
The technical problem that present invention mainly solves be to provide one can effective etch-proof steel, modern's demand to steel can be met.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide the one can effective etch-proof steel, the material composition of described steel includes carbon, silicon, phosphorus, nickel, chromium, molybdenum, vanadium, ferrum and impurity, described steel is by weight percentage, including material composition have: carbon 0.04-0.17%, silicon 0.33-0.4%, phosphorus≤0.02%, nickel≤0.02%, chromium≤1.36%, molybdenum 0.25-0.95%, vanadium≤0.015%, ferrum and impurity: surplus, after the process for making of described steel includes heating bloom slab, carry out again rolling prolonging into steel band, and cooling is rolled into crude steel volume.
In a preferred embodiment of the present invention, described steel by weight percentage, including material composition have: carbon 0.11%, silicon 0.37%, phosphorus 0.01%, nickel 0.01%, chromium 0.72%, molybdenum 0.55%, vanadium 0.007%, ferrum and impurity: surplus.
In a preferred embodiment of the present invention, described in roll and prolong technique and realized by roughing mill and finishing mill.
In a preferred embodiment of the present invention, described cooling technique is realized by water spray on described steel band.
The invention has the beneficial effects as follows: the present invention can effective etch-proof steel, prevent the surface corrosion of steel from getting rusty, it is possible to effectively to extend the service life of steel part, long-time use after the surface of steel the most sparkling clean, do not interfere with attractive in appearance, do not interfere with use yet.
