Q355D steel yog tshwj xeeb tshaj yog haum rau qis - qhov kub thiab txias ib puag ncig vim yog vim li cas hauv qab no:
1. Zoo heev Toughness: Q355D steel nthuav tawm superior cuam tshuam toughness, tso cai rau nws tiv taus nkig tawg nyob rau hauv qis - kub. Cov yam ntxwv no ua kom muaj kev ncaj ncees thiab kev nyab xeeb ntawm cov khoom hauv qhov chaw txias.
2. Txo cov kav dej-rau-Brittle Transition Temperature: Q355D steel muaj qhov txo qis dua- mus rau- nkig hloov kub, uas txhais tau tias nws tseem tawv thiab ductile txawm nyob rau hauv qis kub. Cov cuab yeej no tiv thaiv tsis ua haujlwm tam sim ntawd thiab muaj kev puas tsuaj loj thaum muaj kev ntxhov siab tsawg - kub.
3. High Yield thiab Tensile Strength: Q355D steel muaj cov txiaj ntsig zoo thiab lub zog tensile zog, ua kom nws tiv taus deformations thiab tswj cov qauv kev ruaj ntseg txawm nyob rau hauv qhov hnyav thiab txias.
4. Zoo Weldability: Q355D steel muaj qhov zoo weldability, kom ntseeg tau tias cov pob qij txha thiab cov kev sib txuas tuaj yeem tsim tau zoo yam tsis muaj kev cuam tshuam cov khoom qis - kub ua haujlwm.
Nrog nws zoo heev toughness, txo kev hloov pauv kub, siab zog, thiab zoo weldability, Q355D steel yog zoo - haum rau cov kev siv nyob rau hauv qis - kub ib puag ncig, xws li Arctic lug, cryogenic cia tso tsheb hlau luam, thiab offshore installation nyob rau hauv cov cheeb tsam txias.
