Abstract
The invention discloses steel with the low temperature resistance. The steel is made from, by weight, less than or equal to 0.03% of carbon, less than or equal to 0.75% of silicon, less than or equal to 2.07% of manganese, less than or equal to 0.1% of nitrogen, 9%-11.5% of nickel, 17%-19% of chrome and the balance iron and impurities. A steel making technology of the steel comprises the steps that hot charging and hot delivering are conducted on mould cast steel ingots, then soaking heating is conducted, and the steel ingots are milled into blooming mill products through a blooming mill and a steel ingot continuous mill. In this way, the steel with the low temperature resistance has the advantages that the raw material components and the raw material component content of the steel are regulated, therefore, the effect that the steel can be used at low temperature is effectively achieved, and even if the steel is not used for a long time, the excellent performance of the steel can still be guaranteed, and the fracture and damage phenomena cannot be generated.
Description
Technical field
The present invention relates to Steel material field, particularly relate to a kind of steel with resistance to low temperature.
Background technology
Strictly speaking, steel is phosphorus content iron-carbon alloy between 0.0218-2.06%.In steel in addition to mainly containing ferrum and carbon, possibly together with multiple elements such as vanadium, these elements have corresponding functional characteristic in steel.Vanadium can strengthen antiwear property and the ductility of steel.Vanadium is all contained, wherein containing substantial amounts of vanadium in M-2, Vascowear, CPM T440V and 420VA in many kind steel.And the different of BG-42 from ATS-34 maximum are exactly that the former contains vanadium.Existing steel the most easily becomes fragile, it is impossible to enough uses, have impact on the range of steel.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of steel with resistance to low temperature, 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 resistance to low temperature, the material composition of described steel includes carbon, silicon, manganese, nitrogen, nickel, chromium, ferrum and impurity, described steel is by weight percentage, including material composition have: carbon≤0.03%, silicon≤0.75%, manganese≤2.07%, nitrogen≤0.1%, nickel 9-11.5%, chromium 17-19%, ferrum and impurity: surplus, the process for making of described steel includes that static ingot is carried out hot charging and heat is sent, carry out soaking heating again, roll into breaking down product by blooming mill and steel billet tandem mill.
In a preferred embodiment of the present invention, described steel by weight percentage, including material composition have: carbon 0.015%, silicon 0.37%, manganese 1.04%, nitrogen 0.05%, nickel 10.5%, chromium 18%, ferrum and impurity: surplus.
In a preferred embodiment of the present invention, described soaking heating process is to carry out in soaking pit.
In a preferred embodiment of the present invention, described breaking down product is pipe, slab or small billet.
The invention has the beneficial effects as follows: the steel with resistance to low temperature of the present invention, raw material components and content thereof to described steel are adjusted, this steel is effectively enable to use at low temperatures, described steel uses the performance still ensuring that it is excellent the most for a long time, the phenomenon will not become fragile, ruptured.
