Cov yam ntxwv tseem ceeb
Lub zog siab: Ob qib muab lub zog muaj zog heev, tseem ceeb heev rau kev thauj khoom -cov kabmob.
Quenched & Tempered (Q): Lawv tau kho cua sov (quenching thiab tempering) kom ua tiav lawv cov khoom, txhim kho toughness thiab lub zog.
Txuj: Kev them nyiaj raws li EN 10025-6 (thiab ISO 630-4), qhia txog kev xa khoom.
Daim ntawv thov: Zoo tagnrho rau kev tsim kho hnyav, cranes, cov khoom siv mining, txuas hniav, thiab lub zog -cov qauv siv tau zoo.
Qhov txawv tseem ceeb: Qib Siab
S620Q: Tsawg tshaj tawm lub zog nyob ib ncig ntawm 620 MPa (megapascals).
S690Q: Tsawg kawg yield zog nyob ib ncig ntawm 690 MPa, ua rau nws muaj zog.
Tej yam khoom siv cuab yeej cuab tam (S690Q Piv txwv)
Yield Strength: Nws txawv nrog tuab (piv txwv li, 690 MPa rau 8-50mm).
Tensile Strength: siab tshaj tawm (piv txwv li, 770-940 MPa rau 8-50mm).
Impact Zog: Feem ntau kuaj ntawm -20℃(xws li, 30 Joules yam tsawg kawg nkaus).
Hauv qhov tseeb, yog tias koj xav tau siab - lub zog steel rau kev thov, S620Q thiab S690Q muab lub zog zoo, nrog S690Q muab cov chav kawm muaj zog ntau dua rau kev tsim qauv zoo dua.
