Amandla aphezulu ensimbi ephantsi ye-alloy (HSLA) luhlobo lwensimbi ye-alloy ebonelela ngeempawu ezingcono zomatshini okanye ukuchasana okukhulu kwi-corrosion kune-carbon steel.Amandla aphezulu ensimbi ephantsi ye-alloy (HSLA) inika ukuchasana kokusingqongileyo okungcono kwaye yomelele ngakumbi kunentsimbi ye-carbon carbon.I-HSLA ikwayi-ductile kakhulu, kulula ukuyidibanisa, kwaye inokwakheka kakhulu.Iintsimbi ze-HSLA aziqhelekanga ukwenziwa ukuhlangabezana nokwakheka kweekhemikhali ezithile endaweni yoko zaziwa ngokuhlangabezana neempawu zoomatshini ezichanekileyo.Iipleyiti ze-HSLA zinamandla okunciphisa iindleko zakho zezinto eziphathekayo kunye nokunyusa imithwalo yokuhlawula ukususela ekubeni izinto ezilula zifumana amandla afunekayo.Izicelo eziqhelekileyo zeepleyiti ze-HSLA zibandakanya iimoto zikaloliwe, iilori, iitrayila, iikhreyini, izixhobo zokugrumba, izakhiwo, iibhulorho kunye namalungu esakhiwo, apho ukonga ubunzima kunye nokuqina okongeziweyo kubalulekile.
I-16 mn yinqanaba elikhulu lentsimbi yamandla aphezulu aphantsi kwe-alloy steel plate kumashishini amaninzi, Ukusetyenziswa kolu hlobo kukhulu kakhulu.Ukuqina kwayo kuphezulu kunentsimbi eqhelekileyo ye-carbon structural iron Q235 nge-20% ~ 30%, ukuxhathisa kwe-corrosion emoyeni ngama-20% ~ 38%.
I-15 MNVN isetyenziswa kakhulu njengeplate yentsimbi yamandla aphakathi.Ibonakaliswe ngamandla aphezulu kunye nokuqina, i-weldability elungileyo kunye nokuqina kobushushu obuphantsi kwaye isetyenziswa ngokubanzi ekwenzeni iiBridges, iibhoyila, iinqanawa kunye nezinye izakhiwo ezinkulu.
Inqanaba lamandla lingaphezulu kwe-500 Mpa, ipleyiti yensimbi ephantsi ye-carbon alloy ayikwazi ukuhlangabezana neemfuno, i-carbon bainite yensimbi ephantsi iyaphuhliswa.Ukongezwa kunye nezinto ezifana ne-Cr, Mo, Mn, B, ukunceda ipleyiti yensimbi ekwenzeni umbutho we-bainite, iyenze ibe namandla aphezulu, iplastiki kunye nokusebenza kakuhle kwe-welding, isetyenziswa kakhulu kwibhoyili yoxinzelelo oluphezulu, isitya soxinzelelo, njl njl. ikakhulu isetyenziselwa ukwakha iibhulorho, iinqanawa, izithuthi, ibhoyila, isitya soxinzelelo, imibhobho yeoli, isakhiwo esikhulu sentsimbi.
