Abstract
The invention discloses steel with oxidation resistance. The steel contains, by weight, 0.15% or less of carbon, 0.35-0.55% of manganese, 0.38% or less of phosphorus, 0.31% or less of sulfur, 6-7% of chromium, 0.44-0.64% of molybdenum and the balance iron and impurities. A steelmaking process of the steel comprises the steps that a continuously cast bloom is firstly subjected to dephosphorization and blooming and then enters a finish rolling mill through a roller bed to obtain the steel which is a steel coil or an ingot plate. In this way, the steel with oxidation resistance will not rust after being used for a long time, the oxidation resisting effect can be achieved without extra maintenance, cost for maintenance can be effectively reduced, the use cost is reduced, and the demands of most enterprises are met.
Description
Technical field
The present invention relates to Steel material field, particularly relate to a kind of steel with antioxygenic property.
Background technology
Steel is a kind of iron-carbon alloy.In steel in addition to ferrum and carbon, possibly together with multiple elements such as chromium, these elements have corresponding functional characteristic in steel.Carbon is present in all of steel, is most important hardening element.Chromium can increase mar proof and the hardness of steel, and it the most important thing is corrosion resistance, have more than 13% be considered rustless steel.Although so crying, if maintaining improper, all steel all can get rusty.Existing steel uses upper antioxygenic property bad, getting rusty, also needing to additionally maintain if preventing from getting rusty, increase cost after long-time use.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of steel with antioxygenic property, can meet modern's demand to steel.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of steel with antioxygenic property, the material composition of described steel includes carbon, manganese, phosphorus, sulfur, chromium, molybdenum, ferrum and impurity, described steel is by weight percentage, including material composition have: carbon≤0.15%, manganese 0.35-0.55%, phosphorus≤0.38%, sulfur≤0.31%, chromium 6-7%, molybdenum 0.44-0.64%, ferrum and impurity: surplus, the process for making of described steel includes continuous casting billet is first passed through dephosphorization process to breaking down, steel are obtained again in roller-way enters into finish rolling milling train, described steel are coil of strip or ingot formula plate.
In a preferred embodiment of the present invention, described steel by weight percentage, including material composition have: carbon 0.07%, manganese 0.45%, phosphorus 0.19%, sulfur 0.15%, chromium 6.5%, molybdenum 0.54%, ferrum and impurity: surplus.
In a preferred embodiment of the present invention, the thickness of described continuous casting billet is 130-220mm.
In a preferred embodiment of the present invention, described finishing mill is provided with 7-10 frame four-high mill.
The invention has the beneficial effects as follows: the steel with antioxygenic property of the present invention, long-time use after still will not get rusty, it is not necessary to additionally carry out maintaining and be just capable of antioxidative effect, it is possible to the effective cost reduced in maintenance, reduce the cost on using, meet the demand of most enterprises.
Detailed description of the invention
Technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, all other embodiments that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of protection of the invention.
