Q345E pepa kila wela

ʻO ke kila Q345 kahi China GB standard Low Alloy High Strength Structural Steel, ʻoi aku ka nui o ka waiwai ma mua o Q235. Wahi a GB/T 1591 – 2008, loaʻa i nā mea Q345 nā māka maikaʻi 5: Q345A, Q345B, Q345C, Q345D a me Q345E.

Q345 kila i maikai weldability, anu & wela workability a me ka corrosion kū'ē. Hoʻohana nui ʻia i nā alahaka, nā moku, nā paila, nā moku kaomi, nā pahu mālama ʻaila, nā mīkini lawe lawe a me nā ʻāpana hana welded kiʻekiʻe.

Waiwai mīkini no Q345E ke kila kila haʻahaʻa:

Mānoanoa (mm)
Q345E	≤ 16	> 16 ≤ 35	> 35 ≤ 50	>50
Ka ikaika hua (≥Mpa)	345	325	295	275
Ka ikaika wili (Mpa)	470-630

ʻO ke kila kila no Q345E haʻahaʻa haʻahaʻa (Heat Analysis Max%)

ʻO ka hui ʻana o nā mea kemika nui o Q345E
C	ʻO Si	ʻO Mn	P	S	V	Nb	ʻO Ti	Al (min.)
0.18	0.55	1.00-1.60	0.025	0.025	0.02-0.15	0.015-0.060	0.02-0.20	0.015

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

FAQ
Q: Pehea ka lōʻihi o kāu manawa hoʻouna?
A: ʻO ka maʻamau he 5-10 mau lā inā loaʻa nā waiwai. a i ʻole he 15-20 mau lā inā ʻaʻole i loaʻa nā waiwai, e like me ka nui.

Q: Hāʻawi anei ʻoe i nā laʻana? He manuahi a keu paha ?
A: ʻAe, hiki iā mākou ke hāʻawi i ka hāpana no ka uku manuahi akā ʻaʻole e uku i ke kumukūʻai o ka ukana.
