Peb cov ASTM A307 Qib A Mild Steel Hex Bolts muaj zog ruaj khov rau kev tsim kho niaj hnub thiab tshuab. Ua los ntawm cov hlau tsis muaj carbon (tsis pub tshaj 0.29% carbon ib ASTM A307), lawv muaj zog tensile 60,000 PSI - siab dua 15% piv rau cov bolts hauv khw muag khoom siv kho vajtse. Cov kev sim los ntawm cov neeg thib peb qhia tias lawv tswj tau 120 ft-lbs torque yam tsis muaj lub taub hau rounding (raws li ASME B18.2.1), ua rau lawv zoo tagnrho rau kev sib txuas hlau lossis cov khoom siv ua liaj ua teb. Qhov zais cia? Peb cov sulfur uas tswj tau (<0.05%) tiv thaiv kev tawg brittle hauv qhov kub khov mus txog -20°F (-29°C). Piv rau lwm cov stainless hlau, koj yuav txuag tau 50-70% ib txhiab daim thaum tau txais daim ntawv pov thawj kev ntseeg siab rau cov ntawv thov uas tsis xeb.
Txhua lub Mild Steel Hex Bolt tau txais kev kho mob npaj txhij rau kev sib ntaus sib tua:
Ua los ntawm kev siv cov pwm Nyiv Pooj (cov qauv nplej tuab dua piv rau kev ua los ntawm kev kub)
Cov xov dov rau ASME B1.1 Class 2A haum (muaj zog dua li cov xov txiav 25%)
Plated zinc raws li ASTM B633 Hom II (sim tshuaj ntsev 96 teev)
sim torque 100% (peb tshem tawm 3% nrog cov qhov tsis zoo ntawm kev ua los ntawm kev zais)
Peb tig lub taub hau mus rau shank hloov pauv - tiv thaiv cov kab nrib pleb hauv cov khoom siv vibrating.
Khiav 18 kab tsis siv neeg nrog:
30 lab daim txhua hli tso tawm (ua haujlwm rau cov khoom siv hauv tsev rau khoom)
Kev kuaj xyuas PMI tiag tiag (Phom XRF txheeb xyuas cov tshuaj lom neeg ntawm txhua daim 100)
Cov cim qib laser-etched (tsis muaj kev ploj mus zoo li cov ntawv nplaum)
Cov pawg ua haujlwm taug qab los ntawm barcode los ntawm lub kauj mus rau lub thawv
Xaj ceev? Peb lub Rotterdam hub muaj 20M+ Qib A hex bolts (1/4"-1" loj) - txhua lub cim CE thiab npaj txhij rau 48 teev EU xa khoom.
