I-Q345E ishidi yentsimbi eshushu eqengqelekayo

I-Q345 steel yi-GB yaseTshayina esemgangathweni eLow Alloy High Strength Structural Steel, ukuxinana kwezinto yi-7.85 g/cm3, amandla e-tensile yi-470-630 Mpa, kwaye amandla esivuno yi-345 MPa, ineempawu ezingcono kune-Q235. Ngokutsho kwe-GB/T 1591 – 2008, imathiriyeli ye-Q345 inamabanga ama-5 asemgangathweni: Q345A, Q345B, Q345C, Q345D kunye ne-Q345E.

Intsimbi ye-Q345 inokuqina kakuhle, ukubanda kunye nokusebenza okushushu kunye nokumelana nomhlwa. Isetyenziswa kakhulu kwiibhulorho, iinqanawa, iibhoyila, iinqanawa zoxinzelelo, iitanki zokugcina i-petroleum, ukuphakamisa oomatshini bokuthutha kunye nezinye iindawo ezidityanisiweyo eziphezulu.

Ipropathi yobuchwephesha ye-Q345E yentsimbi ephantsi ye-alloy:

Ukutyeba (mm)
Q345E	≤ 16	> 16 ≤ 35	> 35 ≤ 50	>50
Amandla esivuno (≥Mpa)	345	325	295	275
Amandla okuqina (Mpa)	470-630

Ukwakhiwa kwemichiza ye-Q345E yentsimbi ephantsi ye-alloy structural (Uhlahlelo lobushushu uMax%)

IiMfuno zobuGcisa kunye neeNkonzo ezongezelelweyo:
♦ Uvavanyo lwefuthe lobushushu obuphantsi
♦ Ukusika kunye ne-welding ngokweemfuno zabasebenzisi bokugqibela
♦ Ukungqongqo ngakumbi kwezinye iikhemikhali eziqulathe
♦ Ukukhutshwa kwesatifikethi sovavanyo lwe-Orginal Mill phantsi kwe-EN 10204 FORMAT 3.1/3.2
♦ Uvavanyo lwe-Ultrasonic phantsi kwe-GB/T2970,JB4730,EN 10160,ASTM A435,A577,A578

FAQ
Umbuzo: Lingakanani ixesha lakho lokuhambisa?
A: Ngokubanzi yi-5-10 iintsuku ukuba iimpahla zikhoyo. okanye yi-15-20 iintsuku ukuba iimpahla azikho kwisitokhwe, ngokobungakanani.

Umbuzo: Ngaba ubonelela ngeesampulu? isimahla okanye yongeziweyo ?
A: Ewe, sinokunikezela ngesampulu yentlawulo yasimahla kodwa ungahlawuli iindleko zothutho.
