Q345D pepa kila ʻōwili wela

GB/T1591 Q345D kila e hana charpy V-notch impacting ho'āʻo ma lalo minus 20 centigrade. He nui nā mea hana ipu adpots i kēia kiʻekiʻe manaʻo ikaika e hana i nā ipu waho i hiki ke hoʻohana 'ia i loko o ka moana hohonu.

Waiwai mekini no ka Q345D haʻahaʻa haʻahaʻa kila kila:

Mānoanoa (mm)
Q345D	≤ 16	> 16 ≤ 35	> 35 ≤ 50	>50
Ka ikaika hua (≥Mpa)	345	325	295	275
Ka ikaika wili (Mpa)	470-630

Hoʻohui kemika no Q345D ke kila kila haʻahaʻa (Heat Analysis Max%)

ʻO nā mea kemika nui o ka Q345D

Koi ʻenehana a me nā lawelawe hou aku:
♦ Hoʻāʻo e pili ana i ka wela haʻahaʻa
♦ ʻOki ʻana a wiliwili e like me nā koi o ka mea hoʻohana hope
♦ ʻOi aku ka koʻikoʻi ma kekahi mau mea kemika
♦ Ua hoʻopuka ʻia ka palapala hōʻike hōʻike ʻo Oginal Mill ma lalo o EN 10204 FORMAT 3.1/3.2
♦ Hōʻike ultrasonic ma lalo o GB/T2970,JB4730,EN 10160,ASTM A435,A577,A578

ʻO kā mākou lawelawe

1. Hāʻawi i nā ʻano ʻano ʻano ʻole a pau, ke kila kalapona, ke kila huila non-ferrous a me nā mea ʻē aʻe.

2. Hāʻawi i nā Laʻana

3. Hāʻawi i ka lawelawe kūkākūkā

4. Ka hā'awi 'ana i ka lawelawe 'packaging ma'amau

5. Ka hāʻawi ʻana i nā lawelawe nui i hoʻohana ʻia
