440C-txias-dov-stainless-steel-coil yog martensitic stainless hlau nrog siab carbon thiab chromium cov ntsiab lus. Tom qab kev kho cua sov, nws muaj peev xwm ua tau lub siab tshaj plaws lub zog, hardness thiab hnav tsis kam ntawm tag nrho cov hlau stainless. Muab piv rau qib austenitic, 440C-txias-kuav los tiag-stainless-steel-coil muaj qhov nruab nrab corrosion tsis kam, piv rau 304. Qhov qib ntawm stainless hlau phaj no tuaj yeem hardened los ntawm kev kho cua sov,
