英语翻译请问material specification B-1 except grain size of ASTM4-

原材料明细表B-1除ASTM4-6的粒径尺寸是必须而无须ASTM 5或更精细
例:
Balanced bellows seals may be required instead of conventional type due to process fluid considerations.Pilot operated valves are acceptable in place of bellows type for clean services.出于对工艺介质的考虑,平衡波纹管密封可能要求替代常规类型.对于洁净用途,允许用辅助操作阀替代波纹管类型.
On expressways the colour of signs may be green instead of blue.快速公路的标志颜色,可能是绿色而非蓝色.
She's always talking at me instead of with me.她从来不是与我交谈,总是冲著我叽叽呱呱说个不停.
（也是很费思量,反复斟酌了的啊.

要求钢材原材料明细表B-1采用ASTM 5或较细规格，但ASTM4-6粒径除外。
仅供参考，望能帮助到你，呵呵！
