ASTM A182 F44 yog cov khoom siv forging specification rau qib 44 stainless hlau, siv los tsim ci forgings lossis forged thiab machined khoom rau kev siv kub.
ASTM A182 F44 Flange yog cov khoom siv rau F44 Super Austenitic Stainless Hlau tau piav qhia tias yog 6% Mo Flanges super austenitic stainless hlau
hlau. Cov hlau sib txuas ua haujlwm nruab nrab ntawm lub zog (feem ntau tshaj 300 MPa yield zog) thiab ductility siab nrog corrosion kuj zoo heev hauv dej hiav txwv thiab ntau yam kev lag luam ib puag ncig. Feem ntau cov hlau muaj PREn (Pitting Resistance Equivalent) ntawm 42-44 uas ua kom ntseeg tau tias kev tiv thaiv pitting corrosion yog siab. Tsis tas li ntawd, cov hlau muab kev tiv thaiv zoo rau crevice corrosion.
