Abstract
The invention discloses a steel having the advantage of low price. The steel is prepared from, by weight, smaller than or equal to 0.2% of carbon, 0.167-0.282% of sulfur, smaller than or equal to 0.04% of nickel, smaller than or equal to 0.04% of chrome, 1-1.45% of molybdenum, 0.55-0.85% of cerium, smaller than or equal to 0.34% of titanium and the balance iron and impurities. A steelmaking technology of the steel comprises the steps that a raw steel roll is put on a line for unrolling, edge cutting, sheet cutting, flattening and stacking, and stacked steel plates are obtained. In this way, the steel having advantage of low price is simple in formula, raw materials are convenient to obtain and wide, the performance of the steel can be ensured, the demand of market can be met through the advantage of low price of the steel, and the steel is welcomed by enterprises and factories.
Description
Technical field
The present invention relates to Steel material field, particularly relate to a kind of steel with the low advantage of price.
Background technology
Strictly speaking, steel is phosphorus content iron-carbon alloy between 0.0218-2.06%.Steel construction mainly uses carbon structural steels and low-alloy structural steel.The main component of steel is ferrum, and in carbon structural steels, pure iron content accounts for more than 99%, and remaining is carbon, in addition with the impurity stayed in smelting process, such as the harmful element such as silicon, manganese, and these element total contents about 1%, but the biggest on steel mechanics performance impact.For improving steel mechanics performance, increase manganese that can be appropriate, silicone content, it is also possible to mix a number of alloying element, be smelt steel alloy.In steel construction alloys in common use steel, alloying element content is less, belongs to low-alloy steel.Present steel cost is high, can increase the production cost of enterprise, it is not easy to application.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of steel with the low advantage of price, 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 the low advantage of price, the material composition of described steel includes carbon, sulfur, nickel, chromium, molybdenum, cerium, titanium, ferrum and impurity, described steel is by weight percentage, including material composition have: carbon≤0.2%, sulfur 0.167-0.282%, nickel≤0.04%, chromium≤0.04%, molybdenum 1-1.45%, cerium 0.55-0.85%, titanium≤0.34%, ferrum and impurity: surplus, the process for making of described steel include reaching the standard grade raw material coil of strip uncoiling, trimming, cut into slices, flatten, stack and obtain sheet pack.
In a preferred embodiment of the present invention, described steel by weight percentage, including material composition have: carbon 0.1%, sulfur 0.224%, nickel 0.02%, chromium 0.02%, molybdenum 1.35%, cerium 0.65%, titanium 0.17%, ferrum and impurity: surplus.
In a preferred embodiment of the present invention, described raw material coil of strip, after uncoiling technique of reaching the standard grade, carries out quenched finishing before trimming technology.
In a preferred embodiment of the present invention, before obtaining described sheet pack, carry out finished product packing.
The invention has the beneficial effects as follows: the steel with the low advantage of price of the present invention, formula is simple, and raw material sources are convenient and extensively, it can be ensured that the performance of steel itself, and the advantage that the price of steel is low can meet the demand in market, is welcome by enterprise and factory.
Detailed description of the invention
