(III) steel exports grew rapidly. The supply and demand of domestic steel market is unbalanced and the export of enterprises. From January to June， China exported . million tons of steel， down %， and tons of billets and ingots were imported， up %. Converting billets into crude steel， the cumulative net export was . million tons，Stainless steel coil a year-on-year increase of %，Cold rolled stainless steel plateWhat is the reason for the shortage accounting for % of Chinas crude steel output. In terms of export price， the average export price of bars and wires from January to June was US dollars per ton， a year-on-year decrease of %; US $ tons of plate， a year-on-year decrease of %.
1 — Good ductility， used for molding products. It can also be hardened rapidly by machining. Good weldability. The wear resistance and fatigue strength are better than those of stainless steel.
mPipeline direct drinking water has developed rapidly. With the development of national economy， pipeline direct drinking water has developed rapidly in domestic cities such as Beijing， Shenzhen， Shanghai and Chongqing， and economically developed medium-sized cities have also actively planned to catch up. In direct drinking water，Stainless steel coil stainless steel pipe system is undoubtedly second to none. At present， domestic high-grade hotels and public places have been equipped or are equipped with direct drinking water pipes.
Production and manufacturing can be divided into hot-rolled pipe， cold-rolled pipe， cold drawn pipe， extruded pipe， etc.
AYandiThe internal and external greasy dirt and sundries at the pipe end shall be completely removed to keep the pipe inside the pipe fittings clean.
SoAfter hot rolling， it is subject to heat treatment and pickling treatment.
Extrusion method means that the heated tube blank is placed in a closed extrusion cylinder， and the perforated rod moves together with the extrusion rod to extrude the extrusion part from the smaller die hole. This method can produce steel pipes with smaller diameter.
Price of stainless steel pipe with mm diameter: according to the current market situation， the price of stainless steel pipe with mm diameter is yuan per ton.
sStainless steel pipe， which was produced and used in China at the end of the s，Stainless steel coil is a new family emerging in the field of pipe materials. It has been widely used in building water supply and direct drinking water pipelines.
NAt this time， we usually answer directly: no! What we produce is stainless steel decorative pipe，Cold rolled stainless steel plateWhat is the reason for the shortage which belongs to stainless steel slotted pipe. It can not be used as stainless steel water pipe. If you want to choose stainless steel water pipe， you must choose stainless steel pipe.

eCStainless steel is a thin， firm， fine and stable chromium rich oxide film (protective film) formed on its surface to prevent oxygen atoms from penetrating and oxidizing， so as to obtain corrosion resistance. Once this film is continuously damaged for some reason， oxygen in the air or will continue to separate out， forming loose iron oxide. Stainless steel plate and stainless steel coil will be lifted for a long time， Stainless steel belt， stainless steel pipe， price advantage， quality guarantee! The metal surface is constantly corroded
Han Jianbiao， pointed out that since， Chinas steel pipe exports have been only or tons per month， of which seamless pipe exports are only about tons per month.
Cold formed alloys can be cut and cold formed. However， due to its high strength and hardness， the alloy needs cold forming more than austenitic steel. Because of its high strength， springback should be fully considered.
Create brilliancez · Rotary shaft press roller， blade， etc. in high-strength corrosion-resistant environment.
FWhen the addition of chromium reaches %， the atmospheric corrosion resistance of steel increases significantly， but when the chromium content is higher， although the corrosion resistance can still be improved it is not obvious. The reason is that when alloying steel with chromium， the type of surface oxide is changed to a surface oxide similar to that formed on pure chromium metal
Corrosion resistance most stainless steel products require good corrosion resistance. Stainless steel pipe is similar to class I and II tableware， kitchen， water heater， water dispenser， etc. Some foreign businessmen also test the corrosion resistance of products: use NaCl aqueous solution to warm to boiling. After a period of time the solution is to drain， wash and dry， and determine the weight loss to determine the degree of corrosion.

rN Series & mdash; Martensitic precipitation hardening stainless steel.
The Chinese brand cold rolled non oriented silicon steel strip (sheet) represents: DW + times of iron loss value (at the frequency of Hz， the waveform is sinusoidal， and the magnetic induction peak is T per unit weight iron loss value) + times of thickness value. For example， dw- represents cold rolled non oriented silicon steel with iron loss value of W / kg and thickness of .mm. Now the new model is represented as W.
