Kila nyenzo kwenye tasnia ina historia ndefu, lakini leo tunazungumza juu ya maendeleo ya kihistoria yaAloi ya Aloi ya Aloi.
Kutoka Vita vya Pili vya Ulimwengu hadi miaka ya 1960,Aloi ya Aloi ya Aloiwalikuwa hasa enzi ya maendeleo ya chuma yenye nguvu ya juu na chuma cha juu-nguvu. Due to the needs of the aviation industry and the development of rocket technology, many new high-strength steels and ultra-high-strength steels appearedSteel grades, such as precipitation hardening high-strength stainless steel and various low-alloy high-strength steels, are its representative steel grades.After the 1960s, many new metallurgical technologies, especially the out-of-furnace refining technology, were widely kupitishwa. Chuma cha alloy kilianza kukuza katika mwelekeo wa usafi wa hali ya juu, usahihi wa juu na kaboni ya chini. Kuunganisha chuma na Ferrite ya Ultra-pure ilionekana tena.Mazao ya chuma kama vile chuma cha pua.
