Stainless Hlau 309 Seamless Raj
Kev Piav Qhia Luv:
Stainless Steel 309 yog cov hlau austenitic uas tiv taus cua sov nrog cov chromium thiab nickel siab.
Kev Ntsuas Hydrostatic ntawm Cov Yeeb Nkab Hlau Stainless:
Cov Hlau Stainless 309 paub txog nws qhov kev tiv taus kub zoo heev, ua rau nws tsim nyog rau cov ntawv thov uas raug rau qhov kub siab. Cov hlau no muaj kev tiv taus zoo rau kev xeb, tshwj xeeb tshaj yog nyob rau hauv qhov chaw muaj kev xeb me ntsis. Cov chromium thiab nickel ntau ua rau cov hlau tiv taus xeb thiab lub zog kub siab. Lo lus "seamless" qhia tias lub raj yog tsim tsis muaj cov seams welded. Cov raj seamless feem ntau nyiam siv rau hauv kev siv siab thiab kub siab vim lawv cov qauv sib xws. Cov Hlau Stainless 309 Seamless Tubes pom cov ntawv thov hauv ntau yam lag luam, suav nrog aerospace, kev ua tshuaj lom neeg, kev ua thermal, thiab ntau ntxiv, qhov twg qhov kub siab thiab qhov chaw muaj kev xeb.
