Insimbi engenasici A403 WP316L iqukethe i-chromium ephakeme kanye nokuqukethwe okuphansi kwekhabhoni. I-Carbon ephansi isho ukuhanjiswa kwendalo kwe-chromium kancane ngenxa yokufudumala. Lolu hlobo lwensimbi luqukethe okuphansi njenge-0.03% yokuqukethwe kwekhabhoni futhi ngaleyo ndlela kunciphise ukuthambekela kwalo ekugculiseni kolunye uhlangothi. Lolu hlobo lwensimbi lungavezwa ngokuqhubekayo kumazinga okushisa acishe abe ngu-1500¡¡ãf ngaphandle kokulungiswa okuhle.
