Cold-rolled seamless steel pipe and hot-rolled seamless steel pipe is different
- Oct 20, 2017 -

Cold-rolled seamless steel pipe and hot-rolled seamless steel pipe is different: cold-rolled seamless steel pipe and hot-rolled seamless steel pipe is two different rolling technology, as the name suggests, cold rolling is in the case of steel at room temperature rolling The hardness of steel is large. (Thickness is different, the price is different) 2, width: 1000mm / 1250mm / 1500mm (non-standard width of the general to increase the price), the temperature is 1.2mm-8 / 3, grade: domestic: (hard, high carbon) Q235-Q215-Q195 (soft, low carbon) Japan: SS400-SS330-SPHC (domestic general apply) CIS: 08KP - 08YU (strong drawing , Deep drawing) Germany: ST12-ST13-ST14 (deep drawing, deep drawing) Pearl steel: ZJ330, etc. 4, volume weight: mainly 15 tons / volume, there are 10 tons below / volume. 5, the production capacity: thickness of 0.9 / 1.2 / 1.5 only bead steel can produce a thickness of 1.5mm Handan Iron and Steel, Baosteel to produce (Handan Iron and Steel poor quality) thickness of the thickness of the material, 1.8mm Benxi Iron and Steel, Anshan Iron and Steel, TISCO can produce 6, product quality and price: CIS: poor quality, low price. 08KP manufacturers have Ukrainian ILLCHY, ZAPROSTAL steel mills, Kazakhstan INSPAT steel mills (of which Ukraine's worst quality, lowest price). 08YU manufacturers have Russian (MMK) Magang (08YU quality is better than 08KP) Japan: good quality, high price The main manufacturer for the six blast furnace factories: Nippon Steel, Sumitomo, NKK, Kawasaki and so on. South Korea: good quality, high price The main manufacturer for the POSCO (Pohang) Taiwan: good quality, high prices, the main manufacturer for the steel, Ye Long. South Africa: better quality than the CIS, second only to Japan and South Korea, the main manufacturer for SODHNA. 1.5-2.0 (not including 1.5, including 2.0) domestic manufacturers of poor quality, more than 2.0 quality to meet the requirements. 1.5 The following mainly need to import, 1.8-2.95 use more of the CIS. 2, width: 1000mm / 1250mm (non-standard width of the general increase) 3, grade: domestic: (hard, high carbon content), the thickness of the cold Q235-Q195 (soft and low carbon content) (more than Q195) Japan: SPCC-SD-SPCD-SD-SPCE-SD (domestic general application) CIS: 08KP - 08YU (deep drawing, deep drawing ) Germany: ST12-ST13-ST14 / ST16 (strong drawing, deep drawing) 4, the use of the status of 1.0mm below the main need to import. Japan: mainly 0.6mm / 0.7mm CIS: mainly 1.1mm the following domestic: mainly 0.8mm above -3.0mm the following 5, product quality: Japan, Korea: the best quality, such as POSCO and other domestic: mid-range, Baosteel best, Anshan Iron and Steel, Benxi Iron and Steel, Panzhihua Iron and Steel, followed by the CIS: the worst quality. The main manufacturer with hot rolling.
