Iyazisa:
Kwintsimi yemveliso yensimbi, amabakala amabini aphumayo - i-S275JR kunye ne-S355JR. Zombini zikumgangatho we-EN10025-2 kwaye zisetyenziswa kakhulu kumashishini ahlukeneyo. Nangona amagama abo evakala ngokufanayo, la manqanaba aneempawu ezizodwa ezibenza bahluke. Kule bhlog, siza kugocagoca kwiiyantlukwano eziphambili kunye nokufana kwazo, sivavanya ukwakheka kweekhemikhali, iipropathi zoomatshini, kunye neefom zemveliso.
Umahluko kukwakheka kweekhemikhali:
Okokuqala, makhe sithethe ngomahluko kwimichiza. I-S275JR yintsimbi ye-carbon, ngelixa i-S355JR insimbi ye-alloy ephantsi. Lo mahluko ulele kwizinto zabo ezisisiseko. Intsimbi yeCarbon iqulethe ubukhulu becala i-iron kunye nekhabhoni, kunye nezixa ezincinci zezinye izinto. Ngakolunye uhlangothi, iintsimbi eziphantsi kwe-alloy, ezifana ne-S355JR, ziqulethe izinto ezongezelelweyo ze-alloying ezifana ne-manganese, i-silicon, kunye ne-phosphorus, ephucula iimpawu zabo.
Indlela yokuziphatha koomatshini:
Ngokubhekiselele kwizakhiwo zomatshini, zombini i-S275JR kunye ne-S355JR ibonisa ukungafani okuphawulekayo. Amandla esivuno esincinci se-S275JR yi-275MPa, ngelixa i-S355JR yi-355MPa. Lo mahluko wamandla wenza ukuba i-S355JR ilungele ukusetyenziswa kwezakhiwo ezifuna amandla amakhulu okumelana nemithwalo enzima. Nangona kunjalo, kufuneka kuqatshelwe ukuba amandla e-tensile ye-S355JR angaphantsi kwe-S275JR.
Ifom yemveliso:
Ukususela kumbono wefom yemveliso, i-S275JR ifana ne-S355JR. Omabini amabakala asetyenziswa ekwenzeni iimveliso ezisicaba nezinde ezifana neepleyiti zentsimbi kunye nemibhobho yentsimbi. Ezi mveliso zenzelwe usetyenziso olwahlukeneyo kumashishini ukusuka kulwakhiwo ukuya koomatshini. Ukongeza, iimveliso ezigqityiweyo ezenziwe ngentsimbi eshushu-eqhutyiweyo engeyiyo i-alloy ephezulu zinokucutshungulwa ngakumbi kwiimveliso ezahlukeneyo ezigqityiweyo.
EN10025-2 umgangatho:
Ukubonelela ngomxholo obanzi, masixoxe ngomgangatho we-EN10025-2 osebenza kwi-S275JR kunye ne-S355JR. Lo Mgangatho waseYurophu ucacisa iimeko zokunikezelwa kobugcisa kwiimveliso ezicaba kunye nezide, kubandakanywa iipleyiti kunye neetyhubhu. Ikwabandakanya iimveliso ezigqityiweyo eziye zaqhubekeka. Lo mgangatho uqinisekisa umgangatho ohambelanayo kuwo wonke amabakala ahlukeneyo kunye neempawu zentsimbi eshushu-eqhutyiweyo engeyiyo i-alloy.
Yintoni i-S275JR kunye ne-S355JR ezifanayo:
Ngaphandle kokungafani kwabo, i-S275JR kunye ne-S355JR zinezinto ezifanayo. Omabini amabakala ahambelana nemigangatho ye-EN10025-2, ebonisa ukubambelela kwimilinganiselo engqongqo yokulawula umgangatho. Ukongeza, banoluhlu olubanzi lwezicelo kumashishini ahlukeneyo ngenxa yeepropathi zabo ezilungileyo, kubandakanya i-weldability elungileyo kunye nokuqhubekeka. Ukongeza, zombini amabakala lukhetho oludumileyo lwentsimbi yesakhiwo kwaye banokunikezela ngezibonelelo zabo ngokuxhomekeke kwiimfuno ezithile.
