Kev piav txog
Ib qho alloy steel seamless yeeb nkab cov hauj lwm lub peev xwm siab nyob ib ncig 20% siab dua li cov yeeb nkab welded, zoo ib yam li cov alloys feem ntau. Raws li ib tug tshwm sim, kev siv cov yeeb nkab seamless yog kev ncaj ncees rau hauv cov ntawv thov uas xav tau kev ua haujlwm siab dua. Tus nqi tau tsim ntau dua li cov yeeb nkab welded, txawm tias muaj qhov tseeb tias nws muaj zog dua. Alloy Steel Seamless kav & cov leeg siv rau cov ntawv thov uas xav tau cov corrosion tsis kam, nrog rau cov nqi zoo thiab tus nqi qis.
