Standard Carbon Steel (Tus Neeg Sawv Cev Qib): Q235, Q255, thiab lwm yam.
Cov yam ntxwv: Tus nqi qis, zoo plasticity, thiab yooj yim rau txheej txheem thiab vuam; Txawm li cas los xij, nws nta qis hardness (HB 130-180), hnav tsis zoo, thiab tsis muaj zog corrosion kuj.
Tus Neeg Sawv Cev Tsawg-Alloy High-Strength Steels: Q355 (yav tas los 16Mn), Q460, thiab lwm yam.
Cov yam ntxwv: Lub zog zoo tshaj plaws (lub zog tensile: 355-460 MPa) thiab toughness piv rau cov pa roj carbon zoo tib yam; me ntsis txhim kho hnav tsis kam; zoo heev weldability; thiab tus nqi nruab nrab.
Cov Neeg Sawv Cev Hnav-Resistant Alloy Steels: Mn13 siab-manganese steel, Cr-Mo steel (xws li, 40CrMo), NM360/NM400 hnav-cov hlau tiv taus, thiab lwm yam.
NM Series: Ua ntej-hardened hnav-cov hlau tsis muaj zog, muaj lub hardness ntawm HB360-400; nws muaj kev hnav zoo heev thiab weldability, nrog rau kev ua tau zoo tag nrho.
