The influence of foreign anti-dumping on Chinese large diameter steel pipe

The influence of foreign anti-dumping on Chinese large diameter steel pipe

Foreign anti-dumping to China the influence of the large diameter steel pipe increases, the most direct impact is to reduce China's steel exports, while domestic and facing the steel pipe steel overcapacity situation, the influence of foreign anti-dumping cases, domestic sales of large diameter steel pipe is flagging.

And according to the Vietnam steel association statistics show that the average price of steel imports from China for $505 a tonne, prices rose by an average of 48% from a year earlier, but still lower than the domestic steel prices. But the department of trade and industry said that Vietnam's domestic steel production enterprises can completely meet the demand of domestic market, but the price cannot compete with China's iron and steel. Therefore, to protect the domestic steel industry development, the department of trade and industry will continue to take trade protection measures and the temporary safeguard measures. To protect the interests of domestic steel enterprises.

Commerce seriously questioned the final anti-dumping duties for my thick plate products, the European commission announced on February 28th, the thick steel plate of the product from the People's Republic of China to make a final anti-dumping investigation, decision of the above products five-year anti-dumping measures, anti-dumping tax rate from 65.1% to 73.7%. Commerce ministry spokesman Sun Jiwen 9, said the Chinese side for the European commission ruled that high rates of serious questions method and decision. The sun said, the European commission in the survey continue to use the method of "country", seriously damage the legitimate interests of the Chinese enterprises. China urges the eu to honor its international treaty obligations under the world trade organization (wto), used the method of "country" termination, fair, just, no discrimination against Chinese enterprises. , he said China reserves the right to take necessary measures to resolutely safeguard China's export enterprises fair rights.

Shanghai Katalor is professional steel manufacturer in China, our products are exported to overseas countries, and obtain the purchaser's consistent high praise.

Information: There are some signs of recovery of S355J2WP steel plate

Information: There are some signs of recovery of S355J2WP steel plate

Considering that the steel market’s seasonal busy season is coming, a media had made a special investigation of S355J2WP steel plate recently.These insider surveyed said that from January to February there is a growth of a blowout type in the S355J2WP steel plate production,increased year-over-year by 13.6 percent, and there is also a 12.6 percent increased year-over-year on the import side. At present, there are more than 130 million tons iron ore stock in the port, and there also has a significantly increased iron ore stock in the steel mills.

At the same time, the shortage supply of S355J2WP steel plate emerged, and the demand forecast of S355J2WP steel plate risen significantly. There are two reasons, the first one is that infrastructure projects increased worldwide, the second one is real estate and auto industry recover leads the requirements increased. And the further investigation of domestic mine enterprise revealed that last year the steel price is at historic lows, most of them slid into loss.The data of the first two months this year shows that the mine enterprise realizes make up the deficits and get surpluses. Minmetals in the survey estimated that the S355J2WP steel plate production will increase year-over-year by 27 percent and the steel & iron materials will increase year-over-year by 14 percent in the first quarter 2017.

A285 Grade A steel dephosphorization

A285 Grade A steel dephosphorization



Dephosphorization refers to reducing A285 Grade A chemical reaction of phosphorus content in liquid steel. Phosphorus is one harmful impurity of A285 steel. A285 Grade A steel plate, when used under the room temperature or lower temperature, easy to brittle fracture, known as "cold reduction". A285 Grade A steel plate in the higher carbon catalog, phosphorus is caused by the more serious the brittleness. No more than 0.045% phosphorus content stipulated in the ordinary steel, high-quality steel requires less phosphorus.

Iron dephosphorization problems in the iron and steel production, has a special significance in the history. The steel mass industrial production began in 1856 Bessemer (H.B essemer),invented by acid Bessemer process. But the Bessemer converter steelmaking can not process dephosphorization; The low phosphorus iron ore and rarely, seriously hindered the development of steel production. 1879 Thomas (S.T homas) invented can handle high phosphorus hot alkaline converter steelmaking process, dephosphorization principle of alkaline slag is then extended to open hearth steelmaking, make a lot of phosphorus ore can be used in the production of iron and steel, for the development of modern iron and steel industry has made a significant contribution.

Shanghai katalor have a first-class equipment, can produce high quality of dephosphorization A285 Grade A steel plate, if you need A285 Grade A steel plate, welcome to consult.

A203 Grade F steel cold extrusion process

A203 Grade F steel cold extrusion process

When forging press, A203 Grade Frough radial flow outward. Forging is used for in the manufacture of flanged shaft parts or flange cup parts.

When extrusion, backward extrusion and compound extrusion are the most widely used in cold extrusion technology of three methods. The metal flow direction is parallel to the axis of the punch.Therefore, there is much information on the three methods are also which is called for the axial compression. As mentioned earlier, the axial compression can made all kinds of solid and hollow A203 Grade F steel, such as the ball head pin, bobbin and shell, shell, etc. Radial extrusion is developed more than ten years, mainly used in communications equipment number plate, bicycle flowers keyboard, etc.

Above are a few basic A203 Grade F cold extrusion deformation mode. With the development of cold extrusion technology, will also cold volume A203 Grade F forging belongs to cold extrusion, etc. Cold extrusion in automobiles, tractors, bearing, telecommunications equipment, instrumentation and other mechanical and electrical manufacturing, or in light industry such as bicycles, sewing machines, as well as the defense industrial system has wide application, it is because it has obvious advantages.

Shanghai Katalor is specialized in A203GR.F material whose business related with trade,processing,storage and transportation for more than ten years.If you have any needs and doubts about this material, please contact us at your convenience.

ASTM Corten A China supplier

corten a




Corten A plate is weather resistant steel which is better suited for heavy and load bearing structures.Corten A is produced from billet castings from blast furnace and hot rolled in a continuous mill for smaller thicknesses and on a four high mill for others. The purity of the steel of fine grade austenitic quality and the addition of special alloys, and provide this steel plates, excellent mechanical characteristics, even at high temperatures and self-passivating properties when exposed tocorrosive agents present in urban atmosphere. This property allows this steel to face down corrosion for longer periods when compared to common steel, even if not painted.

Corten A Hot Forming: Normally it is carried out in a temperature range of 800 °C to 1050 °C. If it is required in different temperature, it is advisable to carry out a normalizing treatment at the end.
Flame Cutting: Normally it is carried out with the usual methods. In general, no preheat is required, but working on plates with a temperature of less than 10 °C shall be avoided.

Corten A Welding: Corten A plate can be easily welded using common procedures used for mild steel plate (spot, TIG, MIG, MAG, electrode etc.). It is however advisable to avoid tempering in the heated zone and therefore to limit the ratio of linear energy to the thickness. Considering the chemical composition, it can be stated that Corten A steel is not subject to cold cracking. Welded structures fabricated with corten a steel does not normally need thermal stress relief treatment.
Refercence Standards: Corten A steel plate to be following standards: NFA35-502-E36W, ASTMA242 and A588, EN10155-Fe510A1K1/DD2K1, S.E.W087.
