Togafitiga vevela Fa'atatau
- Fa'amauina o 20CrNiMo Alloy fa'atulagaina uamea
Fa'asa lemu i le 850 ℃ ma fa'ataga le taimi, tu'u le sila e fa'avela lelei, Ona fa'alili malie lea i totonu o le ogaumu. O le u'amea u'amea 20CrNiMo o le a maua MAX 250 HB (Brinell maaa).
- Faʻamaʻaʻaina o le 20CrNiMo Alloy structural steel
Fa'avevela lemu i le 880-920°C, Ona uma loa lea o le fa'asusu i le vevela lea e tineia i le suauu. Ita i le taimi lava e o'o ai meafaigaluega i le vevela o le potu.

Talosaga
GB 20CrNiMo uamea o loʻo faʻaaogaina lautele mo le tele o faʻaoga i le faʻaaogaina i totonu o fale gaosi oloa ma inisinia mo tagata e umia meafaigaluega ma isi vaega faapena. Talosaga masani e pei o tino valve, pamu ma mea faʻapipiʻi, Shaft, le maualuga o le uta o uili, faʻamau, faʻaulu ulu-lua, mea, ma isi.
Tele masani ma le Onosa'i
u'amea lapotopoto pa: Diameter Ø 5mm - 3000mm
Papa uamea: Mafiafia 5mm – 3000mm x Lautele 100mm – 3500mm
Pa uamea Hexagonal: Hex 5mm - 105mm
O isi 20CrNiMo e le'i fa'amauina le lapopoa, fa'amolemole fa'afeso'ota'i la matou 'au fa'atau.
Fa'agasologa
GB 20CrNiMo u'amea uamea lapotopoto pa ma vaega mafolafola e mafai ona tipi i lou lapoa manaomia. E le gata i lea, e mafai foi ona tuʻuina atu le paʻu uʻamea uʻamea 20CrNiMo, e tuʻuina atu ai se paʻu uʻamea uʻamea maualuga maualuga i lau faʻamaliega manaʻomia. E le gata i lea, o le GB 20CrNiMo uamea o loʻo avanoa foi e pei o le Ground Flat Stock / Gauge Plate, i tulaga masani ma le le masani ai.
