All decreased in varying degrees, with an average decrease of 7%. In terms of varieties, the prices of construction wire rod and rebar, which account for a large proportion of China's steel output, fell by 9% and 7% respectively, the vibration process of mold is matched with protective slag which can improve the yield of 10%, save energy and shorten the production cycle, so as to improve the yield of molten steel.

The requirements for weldability and weldability vary from product to product. A tableware usually does not need welding performance, and even includes some pot enterprises. However, most products require good welding performance of raw materials, such as class II tableware, thermos cup, water heater, water dispenser, etc.

.There are ba face, 2b face, (white skin), 2D face, (frosted), HL (wire drawing), 8K face and other surfaces with good quality and brightness.

  409— Cheap model (British and American), usually used as automobile exhaust pipe, is ferritic stainless steel (chromium steel).

Seamless stainless steel pipe, also known as stainless steel pipe, is made of steel ingot or solid pipe blank through perforation, and then made by hot rolling, cold rolling or cold drawing. The specification of seamless steel pipe is expressed by outer diameter * wall thickness mm. With the implementation of China's reform and opening up, and a large number of urban houses, public buildings and tourism facilities have been built, which puts forward new requirements for hot water supply and domestic water supply. In particular, people pay more and more attention to the problem of water quality, and the requirements are also increasing. Galvanized steel pipe, a common pipe, will gradually withdraw from the historical stage under the influence of relevant countries because of its corrosivity. Plastic pipe composite pipe and copper pipe have become common pipes in the pipeline system. However, under certain circumstances, stainless steel pipe has more advantages, especially the stainless steel pipe with wall thickness of only 0.6 ~ 2mm. In high-quality drinking water system,Corrugated stainless steel pipe, hot water system and water supply system that puts safety and sanitation first it has the characteristics of safety, reliability, sanitation, environmental protection, economy and applicability. It has been proved by engineering practice at home and abroad that it is one of the new, energy-saving and environmental protection pipes with good comprehensive performance of water supply system. It is also a very competitive water supply pipe,2205 stainless steel plate, which will play an incomparable role in improving water quality and people's living standards.

Stainless steel pipe appeared in Foshan, Guangdong Province in the tenth generation of the last century. With the rapid development of science and technology in recent decades, most people, including many people in the industry, do not know much about the classification and application of stainless steel pipes. Take stainless steel pipe for example.

Therefore, the field with high utilization rate of stainless steel with high competitiveness and comprehensive quality will also be an important part of the plan.

Theoretical weight: Cr Ni austenitic stainless steel austenitic stainless steel (kg / M) s-wall thickness (mm)

equipment maintenance .Relevant information stainless steel export is an important part of China's export economy. It plays an important role in stimulating China's economic growth. However, from the current situation of China's stainless steel foreign trade, China's stainless steel export has encountered great resistance.

(soft, 1 / 23 / 4h) and other primary and secondary stainless steel coils.

(II) The price of steel has been running at a low level. From January 31 to June 2012, the overall performance of the domestic steel market was depressed. With the substantial release of crude steel production capacity the market supply and demand fell into an imbalance, and the steel price entered a downward channel, which has been weak for more than four months. As of June 26, 2013, the steel price index had dropped to 100.48 points, lower than the first 6 points. The prices of eight steel varieties mainly counted by the iron and steel industry association were lower than the first 6 points

Mechanical properties when the steel or sample is stretched, when the stress exceeds the limit, the steel or sample continues to have obvious plastic deformation, which is called yield, and the small stress value when the yield phenomenon occurs is the yield point.

Application field: tubular boiler for pipeline in harsh seabed environment product description: ultra (ultra) critical unit is the basis of modernization of power generation equipment and energy conservation and emission reduction. Among the important pressure parts of ultra (supercritical) boiler, superheater and reheater are the parts with high working temperature and bad working environment. Previously, all such materials used in China were imported from abroad, while only 10 steel material manufacturers in the world have limited capacity. Such materials have a large gap, expensive import prices, difficult procurement and short supply, which seriously affected the production of ultra supercritical boilers and the development of electric energy in China. At present, China's demand for utility boiler tubes is about 30000 tons, and with the continuous improvement of ultra (supercritical) power generation technology, the demand is expanding. Several large domestic enterprises have invested a lot of human and financial resources in the R & D and production of such products, and have made considerable achievements. On the one hand, it has made its own contribution to the development of national electric power industry, but also brought considerable economic benefits to enterprises.

It has good local corrosion resistance. Compared with austenitic stainless steel with the same alloy content its wear-resistant corrosion and fatigue corrosion properties are better than austenitic stainless steel.

.In order to protect the welding pool well with argon and facilitate the welding operation, the center line of tungsten electrode and the workpiece at the welding position shall be kept 80 ~ 85° Angle, the included angle between filler wire and workpiece surface shall be as small as possible, generally 0-DEG; about.

Cold drawn (rolled) seamless steel pipe: round billet → Heating → Perforation & rarr; Lead & rarr; Annealing & rarr; Pickling → Oiling (copper plating) → Multi pass cold drawing (cold rolling) → Blank tube & rarr; Heat treatment & rarr; Straightening & rarr; Hydrostatic test (flaw detection) → Mark & rarr; Warehousing.

Ti-5a alloy with improved titanium and overall corrosion resistance has been used to manufacture u and Pu solution evaporation boilers and heat recovery evaporation boilers in Donghai reprocessing plant, Japan. In addition, because zirconium has stable corrosion resistance in the environment, zirconium is used in its continuous dissolution tank in the reprocessing plant in liusuo village, Aomori County, Japan. The US Academy's ruling that the countervailing duty is not suitable for products from non market economy countries has just given China's steel pipe enterprises a little relief. The anti-dumping stick from the EU has given a heavy blow to hundreds of domestic stainless steel pipe manufacturers.
