Abstract
The invention discloses steel with low maintenance cost. The steel comprises carbon, manganese, silicon, sulfur, phosphorus, molybdenum, chromium, vanadium, iron and impurities. The steelmaking technology of the steel includes the converter steelmaking technology, and the converter steelmaking technology comprises the operation steps of oxygen supplying, slag forming, warming, deoxidizing agent adding and alloying. According to the mode, the steel with the low maintenance cost can be adopted for producing and machining or site manufacturing, the maintenance cost in the later period is not high, the total cost investment can be effectively lowered, and later maintenance becomes simple. Thus, the steel is popular with consumers and is prevented from being eliminated by the market.

Background technology
Steel are widely used, various in style.The mankind are the longest to application and the research history of steel, but until 19th-century Bessemerizing is invented, producing of steel is all the inefficient work of high cost.Nowadays, steel become with its cheap price, reliable performance and use one of most material in the world, are compositions indispensable in building industry, manufacturing industry and people's daily life.The existing steel later stage needs to put into huge cost and safeguards, virtually adds total price, can be gradually by market.
Summary of the invention
The technical problem that present invention mainly solves is to provide the steel that a kind of maintenance cost is low, can meet modern's demand to steel.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide the steel that a kind of maintenance cost is low, the material composition of described steel includes carbon, manganese, silicon, sulfur, phosphorus, molybdenum, chromium, vanadium, ferrum and impurity, described steel is by weight percentage, including material composition have: carbon 0.078-0.13%, manganese 0.37-0.58%, silicon 0.185-0.356%, sulfur≤0.08%, phosphorus≤0.023%, molybdenum 0.26-0.34%, chromium 0.97-1.25%, vanadium 0.14-0.32%, ferrum and impurity: surplus, the process for making of described steel includes converter steelmaking process, described converter steelmaking process include oxygen supply, slag making, heat up, killing, alloying operating procedure.
In a preferred embodiment of the present invention, described steel by weight percentage, including material composition have: carbon 0.96%, manganese 0.46%, silicon 0.278%, sulfur 0.05%, phosphorus 0.014%, molybdenum 0.28%, chromium 1.04%, vanadium 0.26%, ferrum and impurity: surplus.
In a preferred embodiment of the present invention, described converter steelmaking process is by blasting oxygen and aoxidizing generation heat.
In a preferred embodiment of the present invention, described converter steelmaking process is oxygen top blown converter steel making or electric furnace steel making.
The invention has the beneficial effects as follows: the steel that the maintenance cost of the present invention is low, use this type of steel to carry out production and processing or building site manufactures, do not worry the too much input of later maintenance cost, can effectively reduce the input of totle drilling cost, and make the later stage safeguard become the simplest, so can be welcome by consumer, will not be eliminated by market.
