TSTE500 steel phaj

Muaj steel DIN TStE500 steel phaj specification ntau yam: thickness ≤ 650 mm, dav ≤ 4500 mm, ntev ≤ 18000 mm. Cov hlau loj dua kuj muaj nyob rau ntawm kev thov. Peb cov hlau phaj DIN TStE500 steel phaj tuaj yeem muab tau raws li Suav tus qauv, Asmeskas tus qauv AISI/ASME/ ASTM, Japanese JIS, German txuj DIN, Fabkis NF, British BS, European EN, thoob ntiaj teb ISO thiab lwm yam qauv. Kev kho cua sov txheej txheem: tswj dov, normalizing, tempering, normalizing ntxiv tempering, tempering, thiab lwm yam.

Hlau phaj DIN TStE500 steel phaj txiav, raws li cov qauv kev faib tawm sib txawv, muaj ntau hom tshwj xeeb. Yog tias muab faib los ntawm kev txiav kub, nws tuaj yeem muab faib ua txias txiav thiab txiav kub. Ntawm lawv, txiav txias, xws li dej dav hlau txiav thiab txiav abrasive, kub txiav yog nplaim taws txiav, plasma txiav thiab laser txiav. Tsis tas li ntawd, peb kuj yuav tsum paub tias cov ntawv qib siab DIN TStE500 steel ntawv tuaj yeem raug txiav nrog nplaim taws, thiab nws cov kev txiav yog yooj yim li cov hlau tsis tshua muaj carbon tsawg, tab sis yuav tsum tau saib xyuas.

Phosphorus yog ib qho teeb meem loj hauv DIN TStE500 steel phaj. Nrog rau qhov nce ntawm phosphorus cov ntsiab lus, lub zog, flexurality thiab hardness ntawm DIN TStE500 steel phaj nce, tab sis lub plasticity thiab toughness poob ho. Hauv particular, qhov kub thiab txias, qhov cuam tshuam ntau dua ntawm plasticity thiab toughness, ua rau txias brittleness ntawm hlau.
