Lus piav qhia luv luv:
UNS S44000 Flat Bars, SS 440 Flat Bars, Stainless Steel 440 Flat Bars Supplier, Chaw tsim tshuaj paus thiab Exporter nyob rau hauv Suav teb.
Cov hlau tsis muaj hlau yog cov hlau alloy uas muaj kev tiv thaiv corrosion siab piv rau lwm cov hlau vim tias muaj cov chromium ntau.Raws li lawv cov qauv crystalline, lawv tau muab faib ua peb hom xws li ferritic, austenitic, thiab martensitic steels.Lwm pab pawg ntawm stainless hlau yog nag lossis daus-hardened steels.Lawv yog cov sib xyaw ua ke ntawm martensitic thiab austenitic steels.Qib 440C stainless hlau yog lub siab carbon martensitic stainless hlau.Nws muaj lub zog siab, nruab nrab corrosion kuj, thiab zoo hardness thiab hnav tsis kam.Qib 440C muaj peev xwm ua tau, tom qab kev kho cua sov, lub zog siab tshaj plaws, hardness thiab hnav tsis kam ntawm tag nrho cov hlau tsis muaj hlau.Nws cov ntsiab lus carbon siab heev yog lub luag haujlwm rau cov yam ntxwv no, uas ua rau 440C tshwj xeeb rau cov ntawv thov xws li pob bearings thiab valve qhov chaw.
