Specifically for Q245R container board Shanghai North Run Metal Materials Co. 021 -56,699,572 Mobile: 15601805059 Contact: Huang Yang Q245R boiler and pressure vessel steel plate in a category is - boiler plate grades that way: and Q345R similar low alloy high strength structural steel grades with yield strength values ??"framed" words and Pressure Vessels "accommodate" the first word of the pinyin letters. For example: Q245R. Q-"framed" Pinyin first letter. 245 - yield strength values. R: "content" Pinyin first letter. Has a special composition and performance is mainly used to make pressure vessels used for the purpose, temperature, corrosion different, the material should be used for container board, are not the same. Delivery status: hot-rolled, controlled rolling, normalizing. The increase between parties to do testing. Such as: 20R, 16MnR, 14Cr1MoR, 15CrMoR, 09MnNiDR, 12Cr2Mo1R, 16MnR (HIC), 20R (HIC), and so commonly used in China for more than classification grades; foreign brands have, for example: SA516Gr60, SA516GR70 so on. Q245R steel can be added niobium, vanadium, titanium, and its content should fill in the quality certificate, the sum of the three elements of content should be not more than 0.050%, respectively, Grades chemical element chemical composition (mass fraction) /% C Si Mn Cr Ni Mo Nb VPS Alt Q245R ≤ 0.20 ≤ 0.35 0.50-1.00 ≤ 0.025 ≤ 0.015 ≥ 0.020 Edit this paragraph mechanical properties of the plate thickness / mm Tensile strength R / (N / m) Yield strength R / (N / m) Elongation A /% Temperature / ℃ impact absorption energy KV2 / J 180 ° bending test bending diameter (b ≥ 35mm) 3-16 400-520 ≥ 245 ≥ 25 0 ≥ 31 d = 1.5a> 16-36 400-520 ≥ 235 ≥ 25 0 ≥ 31 d = 1.5a> 36-60 400-520 ≥ 225 ≥ 25 0 ≥ 31 d = 1.5a> 60-100 390-510 ≥ 205 ≥ 24 0 ≥ 31 d = 2a> 100-150 380-500 ≥ 185 ≥ 24 0 ≥ 31 d = 2a Edit this paragraph Common Specifications Material Specification Thickness * Width * Length (mm) Weight (t) Name Q245R 8 * 1500-4000 * 6000-15000M 269.365T boiler container board Q245R 10 * 1500-4000 * 6000-15000M 182.034T boiler container board Q245R 15 * 1500-4000 * 6000-15000M 351.235T boiler container board Q245R 20 * 1500-4000 * 6000-15000M 215.164T boiler container board Q245R 25 * 1500-4000 * 6000-15000M 264.593 T Boiler container board Q245R 30 * 1500-4000 * 6000-15000M 346.846T boiler container board Q245R 35 * 1500-4000 * 6000-15000M 172.046T boiler container board Q245R 40 * 1500-4000 * 6000-15000M 423.564T boiler container board Q245R 45 * 1500-4000 * 6000-15000M 153.927T boiler container board Q245R 50 * 1500-4000 * 6000-15000M 268.348T boiler container board Q245R 55 * 1500-4000 * 6000-15000M 224.823T boiler container board Q245R 60 * 1500-4000 * 6000-15000M 492.658T boiler container board Q245R 65 * 1500-4000 * 6000-15000M 342.716T boiler container board Q245R 70 * 1500-4000 * 6000-15000M 364.834T boiler container board Q245R 75 * 1500-4000 * 6000-15000M 422.296 T Boiler container board Q245R 80 * 1500-4000 * 6000-15000M 536.392T boiler container board Q245R 85 * 1500-4000 * 6000-15000M 286.328T boiler container board Q245R 90 * 1500-4000 * 6000-15000M 284.069T boiler container board Q245R 100 * 1500-4000 * 6000-15000M 291.426T Q245R boiler container board lot size is not listed can be cut to length pinning a lot of double boiler container board Edit this paragraph boiler container board commonly used grades: Q245R Q345R Q370R 13MnNiMoR 15CrMoR 12Cr2Mo1R 14Cr1MoR and so is the new standard GB713-2008 outside the main subject of 10CrMo910 11CrMo9 -10 15Mo3 13CrMo44 19Mn6 BHW35 13MnNiMo54 10Cr0.5Mo 2.25Cr1Mo 1.25Cr0.5Mo 16Mo3 13CrMo4-5 P265GH P295GH P235GH P355GH
