WSTE500 steel phaj

Raws li EN 10025-2, S275J2 steel phaj yog tsuas yog siv nyob rau hauv kev tsim kho kev lag luam thiab mechanical engineering, ntim, tank thiab dov steel profiles xws li lub kaum sab xis steel, steel qauv, H-beam, T-section. Rau S275J2 carbon steel, yog tias cov neeg siv khoom xav txhim kho kev ua haujlwm ntawm cov hlau thaum siv, peb cov engineers tseem pom zoo kom normalizing kev kho cua sov. Tsis tas li ntawd, cov hlau yuav tsum raug ntsuas qhov ntsuas kub ntawm -20 ° C.

DIN WStE500 steel phaj, raws li rau cov tshuaj muaj pes tsawg leeg, cov ntsiab lus sib txawv yog nyob rau hauv cov ntsiab lus carbon, thaum cov ntsiab lus carbon yog A283Gr. d tsis ntau tshaj 0.27%, thiab siab dua qib C (≤0.24%); Raws li cov khoom siv kho tshuab, qhov sib txawv ntawm lub zog tensile thiab lub zog tawm los, thaum ASTM A283 Gr.D muaj lub zog tensile ntawm 415-550MPa (60-80 ksi) thiab qib ASTM A283 D muaj lub zog tawm ntawm 230MPa (33 ksi. ).
