On March , it reached a historical high of . million tons, an increase of . million tons over the previous high, including . million tons of construction steel inventory, accounting for % of the total inventory. After that, with the increase of seasonal consumption, the inventory gradually fell back to . million tons on July . The oversupply in the market also pushed up the inventory of steel mills. In mid March, the steel inventory of key enterprises reached a historical record reaching . million tons, a year-on-year increase of %. In late June, it fell to . million tons still an increase of % over the beginning. Professional stainless steel plate, stainless steel coil, stainless steel belt, stainless steel pipe and other products have a complete variety and sell well at home and abroad. The equipment has a long service life! Products lead the industry in wire products. Welcome to inquire. An increase of % over the same period in .This material without titanium and niobium has an inherent tendency of intergranular corrosion. Intergranular corrosion can be reduced by adding titanium and niobium and stabilizing treatment. It is a kind of high alloy steel that can corrode in air or chemical corrosive medium. Stainless steel has beautiful surface and good corrosion resistance. It does not have to undergo surface treatment such as color plating to play a role of rust freeIndustry management,With the implementation of China's reform and opening up, the national economy has achieved rapid growth, 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 . ~ mm. In high-quality drinking water system, 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, seamless steel tube (ybt- (yb- aviation conduit A seamless steel pipe small diameter stainless steel pipe seamless steel pipe for high pressure boiler low and medium pressure boiler pipe stainless acid resistant extremely seamless steel pipe seamless steel pipe for petroleum cracking seamless steel boiler and heat exchanger Ferritic and austenitic alloy pipe general purpose austenitic stainless steel pipe and welded pipe austenitic stainless steel seamless steel pipe welded steel pipe welded steel pipe carbon steel, Ferritic and austenitic alloy steel pipe) General requirements General requirements for ferrous and alloy steels for special purposes General requirements for carbonDeformation strengthening of austenitic stainless steel stainless steel has good cold deformation performance. It can be cold drawn into very thin steel wire and cold rolled into very thin steel strip or steel pipe. After a large amount of deformation, the strength of the steel is greatly improved, especially when rolling in the subzero temperature zone. The tensile strength can reach more than MPa. This is because in addition to the cold hardening effect there are also superimposed Deformation induced M transition.

Stainless steel pipes can be divided into CR series ( Series), Cr Ni series ( Series), Cr Mn Ni series ( Series) and precipitation hardening series ( Series). Series & mdash; Cr Ni Mn austenitic stainless steel series & mdash; Cr Ni austenitic stainless steel.Honest managementAt low temperature, ferritic stainless steel pipe has low-temperature brittleness like carbon steel, but austenitic steel does not. Therefore, ferritic or martensitic stainless steel produces low-temperature brittleness, while austenitic stainless steel or nickel base alloy does not show low-temperature brittleness. Sus (Cr) and SUS (cr) of ferritic stainless steel pipe It shows that the impact value decreases sharply at low temperature. Therefore, high purification process can be considered. With the help of C and N level, the embrittlement temperature is in the range of - ℃ to - ℃Mechanical properties when the steel or sample is stretched, when the stress exceeds the limit, even if the stress is no longer increased,MomostenangoStainless steel honeycomb tube, 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.The specific steps of continuous casting billet process of stainless steel pipe fittings are as follows: according to different steel grades, the vibration process of mold is matched with protective slag, which can improve the yield of %, save energy and shorten the production cycle, so as to improve the yield of molten steel.Momostenango, which can not be compared with cast iron pipes, stainless steel pipe for heat exchanger and seamless steel pipe for chemical industry (crnit) qhyad crnimosi duplex stainless steel seamless steel pipe.
