Tsawg Alloy Siab Zog Choj Choj Lub Tsev Hlau Phaj

Tsawg Alloy Siab Zog Lub Tsev Hlau tau tsim cov khoom tshwj xeeb tsim los tiv thaiv cov khoom siv hnyav, thiab cov kev sib tw ib puag ncig, thiab kev nyuaj rau kev tsim kho. Cov paib no ua ke cov ntsiab lus tsawg, kev muaj zog siab, tawv, thiab kav ntev, ua rau lawv zoo tshaj plaws rau cov neeg choj tseem ceeb. Hauv qab no yog cov ncauj lus kom ntxaws saib ntawm lawv cov yam ntxwv, kev siv, thiab cov kev qhia tshwj xeeb:

1. Cov Qauv Tseem Ceeb thiab Qib

Tus qauv:

Phiaj suav: GB \/ T 1591 (Tsawg Alloy Lub Zog Lub Zog Zog Txheej txheem qauv), GB \/ T 714 (Choj Hlau).

Yu Laus teb: En {10025-3 \/ -4 (nplua-nplej cov qauv hlau).

Usa: ASTM A709 (High-zog tsawg-alloy steel rau choj).

Cov qib kawm:

Phiaj suav: Q345QD, Q370QE, Q420qE, Q420qe ("Q4 Denotes Choj Hlau;

Yu Laus teb: S355NL, s420ml (li qub los yog thermomechanical dov, nrog "l" qhia tias tsawg-kub kev nruj me ntsis).

Usa: ASTM A709 GR50, Gr70 (Gr500 (Gr50: tawm lub zog ntau dua los yog sib npaug ntawm 345 MPA lossis sib npaug).

 

2. Cov Khoom Siv Neeg Kho Tshuab

Teem nqi	Yield zog (RELE, MPA)	Tensile lub zog (RM, MPA)	Elongation (%)	Cuam tshuam kev xeem (ntsuas kub, KV2, J)
Q345QD	Ntau dua los yog sib npaug rau 345 (tsawg dua lossis sib npaug rau 16 hli)	470–630	Ntau dua los yog sib npaug rau 21	{{0 {0}} degree, ntau dua los yog sib npaug ntawm 34J
Q420qe	Ntau dua los yog sib npaug rau 420 (tsawg dua los yog sib npaug rau 16 hli)	520–680	Ntau dua los yog sib npaug rau 19	{{0 {0}} degree, ntau dua los yog sib npaug ntawm 27J
ASTM A709 GR50	Ntau dua los yog sib npaug rau 345	450–620	Ntau dua los yog sib npaug rau 18	{{0 {0}} degree (yeem), ntau dua lossis sib npaug ntawm 27J

 

 

 

 

 

 

 

 

Cov Nta Tseem Ceeb:

Siab zog-rau-qhov hnyav piv: Txo cov khoom siv thiab qhov hnyav piv rau cov hlau.

Qeeb zog tsis kam: Tsim kom walland cyclic thau khoom los ntawm kev khiav tsheb thiab ib puag ncig kev tshee.

Tsawg-kub nyuaj: Cov qib kawm zoo li Q345qe lossis S355NL ua tau zoo hauv huab cua txias (cuam tshuam kev sim ntawm {2}}}} degree).
