    · Sal solution: 50 (+/- 5) g/l of NaCl. Water is demineralized and salt purity is 99.5%.

    · Environmental temperature: 35 °C.

    · pH of salt solution is 6.8.

    · Volumen of salt solution is 38.4 ml/day.

    · Density of salt solution is 1,030 g/cm3.

    · Spraying is 1.5 (+/- 0.5) ml/h.

    Test Result :NSS can endure 300 hours ;500 hours; 800 hours

     

     

    In the whole crafts process, there are 2 times remove hardening forces: the first remove hardening force in the heat treatment process, hardening force remove is about 80%; the second remove hardening force in the surface treatment process, hardening force remove is about 90%-95%. Therefore, the piston rod is not easily deformed during use or transportation.
