Nylon is predominantly used past the useful pressure range of TFE because of its ability to resist permanent deformation (or creep), and recovery after load.
The negative creep deformations during compressive creep and the range of temperature and stress at which negative creep occurred increased after adding some Mn to ZA27 alloy.
加入锰后，合金在压蠕变过程中的负蠕变量及出现负蠕变的温度和应力范围增大。

Changed Rangecreep quantity upgrade from 60min to 45min. Siege follows this as well. Melee creeps quantity upgrade frequency changed to a few minutes sooner than usual.
