Kuv puas yuav tsum xaiv 316 stainless hlau yeeb nkab lossis 304 stainless hlau yeeb nkab?
Rau kev siv sab hauv tsev lossis sab nraum zoov, yog tias tus nqi yog qhov tseem ceeb, 304 stainless hlau yuav tsum raug xaiv; Txawm li cas los xij, rau qhov chaw hnyav uas muaj cov dej ntsev, tshuaj lom neeg, lossis cov tshuaj chlorides siab, 316 stainless hlau yuav tsum raug xaiv vim nws qhov kev tiv thaiv zoo tshaj plaws los ntawm nws cov ntsiab lus molybdenum. Rau feem ntau siv txhua hnub, 304 yog ib qho kev xaiv nyiaj txiag thiab tsim nyog, thaum rau tej yaam num nyob rau hauv ntau corrosive ib puag ncig, 316 sawv cev rau lub sij hawm ntev zoo dua - peev.
Puas yuav 304 stainless hlau xeb hauv dej?
304 stainless hlau muaj zog heev tiv thaiv atmospheric corrosion, dej corrosion, thiab ntau yam tshuaj corrosion. Tsis tas li ntawd, 304 stainless hlau yog ib qho yooj yim rau txheej txheem, ua rau nws yog ib qho khoom siv rau cov hlau castings thiab dav siv nyob rau hauv lub twj tso kua mis thiab valve Cheebtsam, khoom noj khoom haus, bearings, kub exchangers, thiab siab hlab ntsha.
Txheej txheem cej luam ntawm 304 Stainless hlau kav
304 stainless hlau yeeb nkab belongs rau austenitic stainless hlau. Nws cov khoom tseem ceeb suav nrog 18-20% chromium, 8-11% npib tsib xee, 2% manganese, 1% silicon, nrog rau qhov seem yog hlau thiab kab tsis huv (<0.1%). This is the most common and well-known type of stainless steel in daily life, widely used in applications requiring moderate corrosion resistance, such as household items, kitchen utensils (pots, pans, tableware), machinery and equipment, and industrial building materials (stainless steel pipes, industrial fittings).
Txheej txheem cej luam ntawm 316 Stainless hlau kav
316 stainless hlau kav kuj muaj rau austenitic stainless hlau. Lawv muaj pes tsawg leeg muaj tsawg kawg yog 16-18% chromium, 11-14% npib tsib xee, 2% molybdenum, 2% manganese, thiab 1% silicon, nrog rau cov seem yog hlau thiab kab impurities (<0.1%). Furthermore, 316 stainless steel contains approximately 2-3% molybdenum, which significantly improves its corrosion resistance in harsh environments, making it particularly suitable for applications exposed to salt water or highly corrosive chemicals.
