Detailed Product Description：	(2 1 / 4Cr-1Mo) production ☆ ☆ SA387GR22CL2 Introduction Scope of the technical conditions applicable to the presence of hydrogen thickness ≤150mm equipment SA387Gr22CL2 steel. ☆ ☆ SA387GR22CL2 perform standard American Standard: ASTM ASME plate size, shape, weight and tolerances shall comply with ASME SA387 / SA387M standards. ☆ ☆ SA387GR22CL2 delivery status steel to normalizing (≥90% bainite ensure accelerated cooling rate) + tempering state delivery, normalizing temperature not exceeding 968 ℃, tempering temperature not lower than 720 ℃. Wuyang steel production of such material steel ☆ ☆ SA387GR22CL2 chemical composition of the chemical composition of steel shall conform to Table 1: Wt% Table 1 Component C Si Mn PS Cr V Mo Nb melting analysis 0.05 ~ 0.15 ≤0.10 0.30 ~ 0.60 ≤0.010 ≤ 0.005 2.00 ~ 2.50 ≤0.010 0.90 ~ 1.10 ≤0.010 product analysis 0.04 ~ 0.15 ≤0.10 0.25 ~ 0.63 ≤0.010 ≤0.005 1.95 ~ 2.60 ≤0.010 0.87 ~ 1.13 ≤0.010 Al Ni Cu Ti Sb * Sn * As * [H] * N * O * ≤0.06 ≤0.20 ≤0.15 ≤0.010 ≤0.003 ≤0.010 ≤0.012 ≤2PPm ≤80PPm ≤30PPm ≤0.06 ≤0.25 ≤0.15 ≤0.010 ≤0.003 ≤0.010 ≤0.012 ≤2PPm ≤80PPm ≤30PPm Note: ⑴ * Analysis of Results Records do not make the acceptance criteria. ⑵ analyzed by melting furnaces, rolling sheet-by-product analysis, sampling and testing. ⑶ temper embrittlement susceptibility factor should meet the following requirements: X = (10P + 5Sb + 4Sn + As) × 10≤15PPm where substitution elements PPm content, such as 0.01% should 100PPm substitute. J = (Si + Mn) (P + Sn) × 10≤100 wherein the percentage content of the element in its substitutes, such as 0.15% to 0.15 should be substituted. P + Sn≤0.012% ☆ SA387GR22CL2 ☆ smelting smelting Methods: electric + LF / VD vacuum furnace smelting and refining methods. After all the plates to simulate the response of its test sample blank sample weld heat treatment process system as follows: After the maximum simulated weld heat treatment: Max PWHT:. After 690 ± 14 ℃ × 26h minimum analog-weld heat treatment: Min PWHT:. 690 ± 14 ℃ × 8-2h mechanical properties ☆ ☆ SA387GR22CL2 mechanical properties of steel shall conform to Table 2 (sample simulation for heat treatment after welding): Table 2 Tensile strength Rm (Mpa) yield point Rp0.2 MPa A% Z% cold bend test b = 2a -30 ℃ Charpy J Notes ① 515 ~ 690 310 ~ 620 ≥18 ≥45 180 ° bend without cracking Note ② ≥54 (mean value) ≥47 (single value) Note: ① impact test when lateral expansion values ??should be recorded and fibrous fracture percentage for reference. ② thickness T≤25mm, d = 2.0a; 25mm
