303se Stainless Hlau: Selenium-Enhanced Dawb-Machining Alloy

 

Muaj dab tsi tshwj xeeb txog 303se muaj pes tsawg leeg?

It contains 17-19% chromium, 8-10% nickel, and 0.15-0.3% selenium (instead of sulfur) to enhance machinability. The selenium forms inclusions that break chips, reducing tool wear without the same corrosion trade-offs as sulfur.​

 

303se ua li cas raws li lub tshuab luam ntawv?

Nws muaj kev zoo heev ntawm daim ntawv tsim kho kom zoo thiab cov khoom siv kom zoo rau cov leej twg, ua rau nws muaj kev phom sij rau leej twg, ua rau nws muaj kev tsim txiaj zoo dua li cov leej txiv uas muaj kev phom sij rau qhov chaw muaj kev tiv thaiv kev mob corrosive me me.

 

Dab tsi yog nws corrosion resistance muaj zog?

303se muaj kev tiv thaiv corrosion zoo dua li 304, ua tsaug rau Selenium cov kev cuam tshuam ntawm cov khoom siv oxide thiab dej khov, ua tau txaus nyob rau hauv cov chaw me me {}}

 

303se sib piv rau 303 hauv cov khoom siv neeg kho tshuab?

Ob qho tib si muaj lub zog zoo sib xws (nyob ib ncig ntawm 515 MPA) thiab Hardness, tab sis 303se muaj ntau dua li 303 rau kev siv dag ntau dua li 303 rau kev sib tw yooj yim dua lossis cov lej yooj yim dua.

 

Cov ntawv thov raug yog dab tsi?

Feem ntau siv nyob rau hauv precision-machined qhov chaw zoo li qub thiab marine kho vajtse uas me me corrosion tsis kam muaj teeb meem {}}
