My steel: Last week, the domestic steel market price fluctuated. Although last week's spot resources were supported by the improvement of the futures and billet prices, the market price still needs demand support. Therefore, for some varieties with smooth shipments, the price has a certain difficulty and easy to fall. However, for the region, some of the market has a backlog of resources after the holiday, most of the operations are mainly maintained by fast shipments, and the price increase is restrained, so the merchants are more cautious. In the fourth quarter, it is difficult to relax the environmental protection policy. Although some regional stocks are under pressure, most of the pessimistic situation of the previous business has improved in the previous week. Therefore, it is expected that the domestic steel market price will be this week (2018.10.15-2018.10.19). Or run in a narrow range.

At present, domestic steel pipe manufacturers face the great challenge of overcapacity in seamless steel pipe, have adjusted the variety structure, eliminated backward production capacity and developed high-quality products. The experimental results show that the controlled cooling process in the hot rolling process of seamless steel tube can control the microstructure phase change process, refine the grain, and improve the mechanical properties of the steel tube.

ASMT A333 1 seamless and welded pipes should be treated to control their microstructure. Tensile test, impact test, hydrostatic test and non-destructive electrical test shall be carried out according to the prescribed requirements. ASTM A333 1 is part of the standard covering wall seamless and welded carbon and alloy steel tubes, designed for low temperature use. ASTM A333 1 grade alloy pipe should be manufactured by seamless or welding process without filler metal in welding operation. Seamless and welded steel tubes for low temperature service:

Capillary rolling is the main deformation process of seamless steel tube production. Its function is to make the wall thickness of the capillary close to or reach the thickness of the finished tube wall, and eliminate the non-uniform thickness of the longitudinal wall generated by the capillary in the process of perforation. The surface quality of the internal and external parts of the waste pipe is controlled, and the outer diameter and roundness of the waste pipe are controlled. The hollow capillary is rolled into a waste pipe near the final size.

1mechanical polishing The 1. advantage is that the parts are smooth and the brightness is high after processing. The disadvantage is that the labor intensity is too big, cause serious pollution, can not process complex parts, the luster can not be consistent, the heat preservation time is not long, the mechanical polishing is suitable for the processing simple parts, and the small and medium parts.

According to foreign media reports, US steel prices seem to be affected by 232 tariffs, tinplate prices are rising sharply, and tinplate manufacturers will reflect price increases in negotiations with customers in 2019. It is reported that since the price of hot rolled strip of raw materials for tinplate production has increased, the price of tinplate in the United States has increased by more than $350/ton since last year. US tinplate manufacturers will begin negotiations with customers on prices starting in 2019 this fall. They will require a 50% price increase when the tinplate price is at a high market level and a 30% price increase when it is at a low market level, which is in line with the price increase of hot rolled products.

Type 304 stainless steel is one of the most common and most commonly used stainless steel grades. It is a chromium nickel austenitic alloy, which contains at least 18% chromium and 8% nickel, which contains up to 0.08% carbon. It can not be hardened by heat treatment, but cold working can produce higher tensile strength. Chromium and nickel alloys provide corrosion resistance and oxidation resistance far better than steel or iron for Type 304. It has a lower carbon content than 302, which minimizes chromium carbide precipitation due to welding and intergranular corrosion. It has excellent molding and welding characteristics. The ultimate tensile strength of the 304 type is 51500 psi, the yield strength is 20500 psi, and the elongation is 40%, 2 ". Type 304 stainless steel has many different sizes and shapes, including rods, corners, circles, plates, slots and beams. This kind of steel is used in many industries for many different purposes. Some examples are food processing equipment, kitchen equipment and appliances, panels, decorations, chemical containers, fasteners, springs and so on.

United Steel Industry Co.,Ltd as member of United Steel Industry Group, is one of the best manufacturers & exporters of steel pipe and pipe fittings in China.

Vale released its second quarter production and sales report for the 2018. According to the report, in the second quarter, Vale's iron ore output reached 96.8 million tons, a record high in the same period in history. In the second quarter, although Vale's offshore inventories increased in support of the continued development of the mixed mining business, sales of iron ore and pellets still recorded a record high in the same period of the previous year, totaling 86.5 million tons, an increase of 4.8 million compared with the same period last year. Ton.

Whether we transport hundreds of miles of water or pipe gas in accordance with federal standards and regulations, our steel pipes and tubular products are durable. They are applicable to the design and manufacture of applications.

The quality of the perforated capillary has a very important effect on the quality of the hot rolled seamless steel tube because of the surface defects or eccentricity (uneven thickness) of the worn capillary. The way pressure pipe punching punching, pushing rotary perforation and perforation. Thick wall seamless steel is mainly used in oil geological drilling pipe, and petrochemical used in cracking pipe, boiler tube, pipe and automobile bearing, tractor, aviation and other precision pipe structures, its manufacturing process: hot rolled seamless steel pipe circle, heating, three porous roller, rolling or extrusion, separation, slurry (or reduced) cooling, straightening,?? water pressure Test (or test) marks - storage.

Regarding the tampering of the product data of the Kobe Steel Works in Japan, the Tokyo Metropolitan Police Department searched 2 classes on the 17th for the alleged violation of the Anti-Unfair Competition Law (falsely marked), and the head of Kobelco and the four factory owners as legal persons. The relevant data is transferred to the prosecution. The Tokyo Local Prosecutor's Office is expected to sue Kobelco and will not sue four responsible persons.

Seamless steel pipe is one of the important products of OCTG products. It is widely used in manufacturing structural parts and mechanical parts, such as petroleum drill pipe, automobile transmission shaft, bicycle frame and steel scaffolding. Compared with other steel tubes, seamless steel tubes have stronger bending and torsion capacity under the same cross-sectional area. It is widely used in the national economy and has the right to "industrial vessels". Therefore, the quality requirements of seamless steel tubes are very demanding.

The European Union official gazette said that the EU will launch protective measures on Thursday (19th) to prevent a surge in steel imports into the EU after tariffs on imported steel and aluminum in the United States. The European Commission has proposed a combination of quotas and tariffs to address EU concerns, and the EU is concerned that steel products that are no longer exported to the United States may turn into the European market. The Lianhe Zaobao quoted Reuters as saying that the quota for 23 steel products was based on the import situation in the past three years, and the imported steel products exceeding the quota will be subject to a 25% tariff. According to reports, the countries that export steel to the EU are mainly China, India, Russia, South Korea, Turkey and Ukraine.

Many people think that stainless steel is not rust steel, of course. The stainless steel pipe elbow anti rust mechanism is to form compact alloy oxide film, isolate oxygen contact and prevent oxidation. So stainless steel is not "stainless steel". Stainless steel has the ability to resist atmospheric oxidation, that is, stainless steel, and has corrosion resistance in acid, alkali and salt media, that is, corrosion resistance. After the Prime steel pipe, the main factors affecting the corrosion of stainless steel are understood.
