Phab ntsa Thickness: 1mm-50mm (Customizable)
Ntev: tuaj yeem kho raws li qhov kev thov
Cov Qauv: ASTM A519, Los yog raws li cov neeg siv khoom tshwj xeeb.
Steel Qib: 4340

Khoom Description

Peb Qhov Zoo

1. Muaj zog thiab siab tawv
Peb 4340 Steel Tube tau txais kev kho cua sov thiab kev kub ntxhov thiab kev kuaj xyuas cov cuab yeej zoo, ua rau muaj zog heev thiab zoo heev. Nws tuaj yeem tiv taus kev ntxhov siab, hnyav, dabtsi yog khoov, torsion, thiab cyclic loads, ua rau nws haum rau shafts, axles, drilling cuab yeej, thiab siab -load structural Cheebtsam.

2. Qhov Loj Loj
Peb cov raj tau txais kev kos duab txias txias thiab kev tswj xyuas nruj, kom ntseeg tau tias txhua lub raj ua tau raws li ASTM A519 cov qauv, tsim nyog rau siab - cov ntawv thov kev siv tshuab engineering.

3. Kev Tswj Xyuas Zoo
Peb cov raj tau dhau los ua cov tshuaj lom neeg muaj pes tsawg leeg, kev ntsuas tam sim no, thiab kuaj ultrasonic kom ua tau raws li ASTM A519 thiab AISI 4340 tus qauv. Cov hlab ntsha yog dawb ntawm cov kab nrib pleb thiab voids, thiab tsis muaj qhov tsis xws luag.

4. Machineability
Peb cov hlab yog nkag rau hauv cov txheej txheem annealed lossis normalized, muab cov machinability zoo rau kev txiav, drilling, tig, thiab milling. Kev ntsuam xyuas metallographic qhia qhov huv thiab zoo ib yam microstructure, ua kom yooj yim rau kev ua haujlwm.

5. Ntim thiab Shipping

Peb cov kav dej tau ntim nrog ntau txoj hauv kev, suav nrog cov ntim yas, lub kaus mom yas, hnab woven, ntoo crates, thiab hlau thav duab. Customized ntim yog muaj, kom ntseeg tau tias txhua lub pob muaj cov ntawv qhia meej thiab cov lej traceability. Peb muab kev thauj mus los hauv hiav txwv, huab cua, thiab av.
