23MNNIMOCR5-4 bar rau kev sib txuas pas nrig yog cov hlau zoo, nrog lub zog siab, siab tawv, hnav tsis kam thiab weldability thiab kev ua haujlwm, dav siv hauv kev tsim cov hlua txuas txuas.
(1) Siab zog thiab toughness:
Nws muaj zog yield zog thiab zoo ductility, ua rau nws tiv taus hnyav loads thiab tiv thaiv deformation. Tsis tas li ntawd, nws muaj kev tiv thaiv siab, uas ua rau nws tsim nyog siv rau hauv qhov chaw hnyav.
(2) 23MNNIMOCR5-4 muaj kev hnav zoo heev:
Nws muaj lub siab tawv hardness, uas txhais tau hais tias nws tuaj yeem tiv taus hnyav hnyav. Qhov no ua rau nws zoo tagnrho rau kev siv cov hlua txuas, vim kev sib txhuam tas li thiab txhuam tuaj yeem ua rau muaj kev puas tsuaj rau lub sijhawm.
(3) Lub steel bar muaj zoo weldability thiab machinability, ua rau nws yooj yim rau cov txheej txheem ntawm kev tsim khoom.
Nws tuaj yeem yooj yim welded thiab tsim rau hauv cov duab sib txawv thiab ntau thiab tsawg, ua rau nws muaj ntau yam.
