06Ni7DR belongs rau steel phaj rau qhov kub siab ntawm lub nkoj.
Tus qauv thawj coj ntawm 06Ni7DR yog GB/T713.1-2023.
1, Kev xa khoom ib txwm muaj ntawm 06Ni7DR yog: normalized lossis normalized + tempered. Yog tias muaj kev pom zoo hauv kev nug thiab kev txiav txim, nws tuaj yeem xa tuaj yam tsis muaj kev kho cua sov.
2. 06Ni7DR yog pom zoo kom normalized ntawm qhov kub thiab txias ntawm (890 degree -950 degree ) hauv kev kho cua sov. Thiab normalizing, thaum tag nrho cov hla ntu kom tau txais qhov kub thiab txias, tsis tas yuav tsum tau tuav thiab feem ntau yuav tsum zam.
European Standard EN {{0}}: 2003 High-temperature performance steel phaj rau kev tsim cov khoom siv nkoj. Tensile zog Rm360-630MPa, tawm lub zog ReH: 235-355MPa, elongation me me 20-24%, me me cuam tshuam KV J degree -20 degree --27J, 0 degree --34J, +20 degree --40J: European Standard EN10028-2: 2003 cov khoom mus txog qhov tuab ntawm 8-260mm. mob: + N normalized, + NT normalized ntxiv rau tempering, + QT quenching thiab tempering.
