JIS G3461 STB510 boiler thiab tshav kub exchanger ua raws li Japanese tus qauv JIS G3461 thiab yog ib tug steel raj rau boilers thiab tshav kub exchangers.
JIS G3461 STB510 carbon steel puag ncig lub raj tuaj yeem tiv taus kev ua haujlwm siab thiab qhia tau zoo heev. Nws qhov tsawg kawg nkaus tensile lub zog ncav cuag 510 MPa thiab nws qhov tsawg kawg nkaus tawm lub zog yog siab li 295 MPa, uas paub meej tias nws muaj feem xyuam rau hauv daim ntawv thov scenarios xws li high-pressure boilers.
JIS G3461 STB510 kub-kuav los tiag raj yog lub nruab nrab-siab boiler raj, feem ntau yog siv rau zus tau tej cov boilers, superheated chav tubes, boiling dej raj, thiab dej-txias phab ntsa raj haum rau ua hauj lwm kub.
