S690QL mkulu mphamvu zitsulo mbale

Chifukwa cha chilengedwe champhamvu kwambiri, kugwiritsa ntchito S690QL kudzalimbikitsa zomanga zowonda kwambiri zokhala ndi kuchuluka kwamalipiro komanso kugwiritsa ntchito mphamvu.
Zambiri zaukadaulo za S690QL zafotokozedwa pansipa.
S690QL - Kusankhidwa kwa Gulu
Magiredi a S690QL ndi awa:
S = Zitsulo Zomangamanga
690 = mphamvu zokolola zochepa (MPa)
Q = Kuthetsa & Kutentha
L = Low notch toughness kuyesa kutentha

S690QL - Mapangidwe a Chemical
Mankhwala a S690QL aperekedwa mu tebulo ili m'munsimu.
