Mhinduro iri nyore ndeyekuti ASTM A490 ine simba guru rekushandisa mabhoti ane heavy-duty heavy-duty heavy-duty heavy-duty heavy-duty heavy-duty heavy-duty heavy-duty heavy-duty heavy-duty heavy-duty heavy-duty heavy-duty heavy-duty heavy. Mabhoti eA325 ane simba shoma rekudhonza re120ksi, nepo mabhoti eA490 ane simba rekudhonza re150-173ksi.

Pamusoro peizvi, kune mimwe misiyano pakati peA490 neA325.

Kuumbwa Kwezvinhu

• Mabhaudhi eA325 anogadzirwa nesimbi ine kabhoni ine simba guru, uye ndiwo anonyanya kuwanikwa mukuvaka zvivako.
• Mabhaudhi eA490 akagadzirwa nesimbi yakasimba kwazvo inogadziriswa nekupisa
• Mabhaudhi eA325 anogona kuvayakanyudzwa inopisauye anowanzo kuwanikwa nependi iyoyo. Mabhaudhi eA325 galvanized anozivikanwa nekuda kwehunhu hwawo hunodzivirira ngura.
• Mabhaudhi eA490 akasimba, haakwanise kunyudzwa nekupisa nekuda kwesimba iri. Nekuda kwesimba guru rekudhonza remabhaudhi eA490, ari panjodzi yekupwanyika kwehydrogen nekuda kwekushandiswa kwemagetsi. Izvi zvinogona kukonzera kutadza kushanda kwebhaudhi nekukurumidza uye zvinogona kushaya simba remuumbirwo.

Kupfeka

Kugadziriswa

Mabhaudhi eA3125 neA325 ese ari maviri anowira pasi pezvinodiwa zveASTM F490 uye anoshandiswa zvakanyanya kumabhaudhi ekuvaka. Kazhinji, mabhaudhi ekuvaka imabhaudhi eheavy-duty hex kana mabhaudhi ekutonga kumanikidzwa anowanzova mapfupi pakureba, mapfupi pane tambo yepakati, uye haagone kuderedza dhayamita yemuviri.

Zvichienderana netsika, zvimwe zvisingabvumirwe zvinotenderwa. Gore ra2016 risati rasvika, ASTM A325 neASTM A490 zvaive zvakasiyana. Kubva ipapo zvakazoiswa muzvikamu zveF3125. Pakutanga, mabhoti eA325 neA490 aifanira kunge aine musoro wehex unorema uye hapana mamwe magadzirirwo aibvumidzwa. Pamusoro pezvo, kureba kweshinda pfupi hakugone kuchinjwa.

Zvisinei, zvichienderana netsanangudzo itsva yeF3125, chero rudzi rwemusoro runobvumirwa uye kureba kweshinda kunogona kuchinjwa. Kuchinja kune zvakajairika zveA325 neA490 zvinotsanangurwa nekuwedzera "S" kune chiratidzo chekugara kwenguva refu chemusoro.

Mumwe musiyano pakureba kweshinda ndewekuti mabhoti eA325 anogadzirwa akawanda mumhando yakazara, chero bedzi ari madhayamita mana kana pasi pakureba. Rudzi urwu rwebhoti runowanzozivikanwa seA325T. Mhando yakazara yebhoti iyi yeA325 haiwanikwe kumabhoti eA490.

Kuedzwa

Mabhoti eA325 galvanized ari kutengwa nenati newasher yakaoma anofanirwa kuongororwa kugona kwayo kutenderera. Kuedza kugona kwayo kutenderera kunoita kuti bhoti rikwanise kugadzira simba rakakodzera rekusunga. Kuti ibudirire, bhoti rinofanira kusvika padanho rekuchinjana uye kuwana simba rinodiwa risati rakundikana zvinoenderana nedhayamita nehurefu hwebhoti reA325 galvanized. Sezvo mabhoti eA490 asingagone kugadzikwa, bvunzo iyi haishande.

Mabhaudhi ese eA490 anofanira kupasa bvunzo yemagnetic particle. Bvunzo iyi inoshandiswa kuona kuti hapana zvikanganiso zviri pasi pevhu kana mitswe musimbi yebhaudhi reA490. Bvunzo iyi haidiwi pamabhaudhi eA325.

Mutsetse Wekupedzisira

Pakupedzisira, mainjiniya wako achatsanangura kuti bhaudhi reF3125 structural bolt raunofanira kushandisa ripi, asi zvakakosha kunzwisisa mutsauko uripo pakati pemagiredhi eA325 neA490. Giredhi reA490 rakasimba kupfuura giredhi reA325, asi simba harisi iro chete rinosarudza bhaudhi. Mabhaudhi eA490 haafanire kunyikwa mumoto kana kugadzikwa nemagetsi. Giredhi reA325 harina kusimba zvakadaro, asi bhaudhi rinodhura zvishoma rinogona kugadzikwa nemagetsi kudzivirira ngura.
