Stainless hlau 347 1.4550
Cov ntaub ntawv no siv rau stainless hlau 347 / 1.4550 kub thiab txias dov daim ntawv, sawb thiab tuav, semi-tiav khoom, rods thiab seem raws li zoo raws li seamless thiab welded steel hlab rau txhua yam thiab dav engineering lub hom phiaj.
Daim ntawv thov
Rau kev tsim kho qhov chaw uas yuav tsum tau resistant mus scaling mus txog 1050 ° C thiab feem ntau inured rau cov nyhuv ntawm sulfurous gases, tshwj xeeb tshaj yog saum toj no 900 ° C, yog tsawg heev.
