BR1500HS high-strength pipe

Steel Co., Ltd. Shandong Heaven car crash beam BR1500HS car crash beam car crash car crash beam lever br1500hs 1524M high tension tube 16MnAI car crash beam distribution and wholesale of high-pressure boiler tubes, low pressure boiler tubes, high-pressure alloy pipe, fertilizer dedicated pipe, oil cracking pipe, stainless steel pipe, hydraulic prop tube, fluid pipe, structural pipe, seamless pipe, galvanized pipe, square and rectangular tube, pipe-selling consumer market, among consumers enjoy higher status, with many retailers and agents to establish a long-term stable cooperative relations. Main products: seamless categories: steel pipe, seamless, non-standard steel pipe, precision steel alloy steel plate: steel plate, plate, manganese plate, high strength steel, high-pressure steel plate steel rod: Alloy round, bearing steel, boiler steel, stainless steel hydraulic types: stainless steel, non-standard stainless steel tubes, precision stainless steel tube stainless steel plate: stainless steel plate, stainless steel plate copper alloys: brass, precision brass, copper alloy tube, copper, copper alloy steel Nickel Alloy: Nickel alloy tube, nickel alloy plate, precision-nickel alloy pipe ∮27x2 ∮32 * 2.5 ∮30 * 2 ∮28 * 2 ∮28 * 2.5 ∮32 * 2 ∮34 * 2.5 ∮28 * 2.5 ∮29 * 2.0 etc ,,,, requirements vary as car manufacturers, as well as the outer diameter of the length of the pipe wall thickness is not the same tensile strength ,, this requires custom hot stamping technology is a dedicated Deposited New technology strength steel. Hot stamping tensile strength of more than 1500MPa, and forming high precision, almost no rebound. This approach can take advantage of the plastic properties of the material to stamping parts, used for automotive structural parts, can improve the safety performance of vehicles, to reduce body weight. At present, only a few units of the hot stamping technology research, to give the corresponding outcome in the mold design, process testing and simulation aspects, but the relationship between process parameters have not been in depth. Hot stamping process is difficult to grasp, the use of simulation technology to optimize the process parameters. In door impact beams, for example, research thermoforming process characterized by ultra-strong steel hot stamping simulation and test a combination of methods, build relationships model punch punching speed and initial pressure and molding temperature, and by experimental verification of the model correct. Experimental steel material is hot-rolled sheet Baosteel 22MnB5, designations BR1500HS, a thickness of 2mm, a density of 7850kg / m3, the critical cooling rate of 15 ℃ / s, the chemical composition of% BR1500HS element C Mn B Si Cr SP mass fraction 0.21 1.35 0.28 0.23 0.004 0.0033 0.0055 hot-rolled state, the hardness of the material is about 193HV, tensile strength at 500 ~ 600MPa properties: yield strength before quenching ≥300MPa, tensile strength ≥600MPa; yield strength after quenching ≥1200MPa, tensile strength ≥1500MPa; automobile manufacturing BR1500HS pipe [BR1500HS how much tensile strength] is weathering a high-strength steel Ingredient Percent (wt%) C 0.19 ~ 0.25 B 0.0008 ~ 0.005 Mn 1.10 ~ 1.4 Cr 0.15 ~ 0.35 Al 0.02 ~ 0.06 Ti 0.02 since 0.05 Si ≤0.40 P ≤0.025 S ≤0.015 its inception, quality-oriented, complete specifications, excellent inexpensive price of purpose, to create a good social and economic benefits, annual sales of Tianjin Steel Tube Company, Panzhihua Iron and Steel several major steel production of a variety of groups, Chengdu Seamless Steel Tube Plant, Baotou Steel, Shanghai Baoshan Iron and Steel, Anshan Iron and Steel, Hengyang Steel Tube factory, seamless, low-pressure boiler tube products, to seek long-term interests of enterprises, laid a stable basis. The main products are; imported and domestic alloy tube; heat-resistant alloys; high-pressure boiler tubes, plates; seamless tube; low-pressure boiler pipe, steel pipe, plate, bar; alloy plate, bar; steel, oil casing, tubing, (oil fields, power plants, chemical plants, boiler plants) with steel, titanium steel, titanium tubes, plates, rods; hot rolled, spiral, straight seam pipe and construction timber and so on.
