◎ 如果熱加工和隨后冷卻的條件符合ENISO3651-2中對產(chǎn)品機械性能和抗晶間腐蝕性的要求,則可以省略固溶處理拴鸵。
*抗晶間腐蝕根據(jù)EN ISO 3651-2進行測試玷坠。在交貨條件下,T ≤ 6mm:有劲藐;在焊接條件下八堡,T ≤ 6mm:有;在致敏狀態(tài)下:無聘芜。
① 對于連續(xù)熱軋產(chǎn)品兄渺,可在詢價和訂購時商定Rp0.2(即表中σs)的最小值提高20MPa,Rp1.0的最小值提高10MPa磁揽。
② 如果在軋制寬度<300mm的帶材情況下寝典,采用縱向試驗件,最小值減小如下:屈服強度-15MPa伺亭,恒定標距的延伸率-5%缅坯,比例標距延伸率-2%。
③ T<3mm:該值適用于標距為80mm藐捉、寬度為20mm的試件铭歪,也可以使用標距為50mm、寬度為12.5mm的試件氛玛。T ≥3mm:該值適用于標距為5.65√S的試件搀薛。
④ 適用于20℃至-196℃之間的任何溫度,機械性能可通過線性插值估計蹂勺。

    ◎ a=air; o=oil; w=water.
    ◎ Scale and annealing colours produced during hot forming, heat treatment or welding may adversely affect the corrosion resistance. They should be removed as far as possible before use, e.g. by pickling.
    ◎ The temperatures of annealing should be agreed for simulated heat treated test pieces.
    ① The solution treatment may be omitted if the conditions for hot working and subsequent cooling are such that the requirements for the mechanical properties of the product and the resistance to intergranular corrosion as defined in EN ISO 3651-2 are obtained and provided these requirements are met even after appropriate subsequent solution annealing.
    ② Re-crystallizing annealing.
    ③ If heat treatment is carried out in a continuous furnace, the upper part of the range specified is usually preferred, or even exceeded.
    ④ The lower end of the range specified for solution annealing should be aimed at for heat treatment as part of further processing,because otherwise the mechanical properties might be affected. If the temperature of hot forming does not drop below the lower temperature for solution annealing.a temperature of 980℃ is adequate as a lower limit for Mo-free steels,a temperature of 1000℃ for steels with Mo contents up to 3% and a temperature of 1020℃ for steets with Mo contents exceeding 3%.
    ⑤ cooling sufficiently rapid.
    ⑥ Minimum holding time:30min.
