SS400 hot rolled steel coil tube works
Ting Fei [SS400 hot rolled steel pipe production volumes of works] Chemical and physical methods of nano materials or mechanical alloying method produced more conservative, some powder and film. Mechanization metallurgical process for the preparation of ultrafine-grained materials technology key is to realize its large strain effects statement. The transfer process in a magnesium alloy ECA P and efficient system of lightweight high-strength low car material extrusion, rolling, rolling and other plastic deformation process the strain level is difficult to satisfy this condition. Thick-walled pipe its production process can be divided into high-frequency welding and submerged arc. Submerged arc welding is generally applicable to the production of large-caliber Longitudinal. Longitudinal thick-walled high production efficiency, relatively low cost, is one of the steel products commonly used on the market today. Submerged arc welding straight seam steel pipe abbreviation of lsaw, high-frequency welding called erw, former factory to be pressure, bending, length flattening and other experiments, the main products were produced according to customer requirements. Large diameter thick-walled paper tube market prices remain steady weakening trend. Thick-walled pipe for the local market, subject to the environment impact the poor, large diameter thick-walled tube volume business mentality pessimistic, but the market is large offer basic to stabilize the main, but the deal has space can be proposed.
Shanghai building materials prices fell sharply this week. Market feedback, to the New Year in mid-December last year, the domestic steel prices rose more than 200 yuan / ton, the business in the hands of the general inventory of resources have a certain profit margin. With the growing demand and the terminal decline of the steel futures fell, businesses accelerate cash shipments will increase, steel prices continued to fall this week, especially steel resources decline to three hundred dollars, and one or two types of resources spread again It has increased. But overall remain low supply current steel market resource specification shortage still exists, Shagang, Wing Steel, transit and other steel plants mentioned specifications are generally not neat, steel prices continue to fall deep trouble, later this week the market some signs of stabilization . Shanghai is expected next week finishing the main building materials prices will be low. Source:http://www.jnsteelpipe.com/
