Kusiyana Pakati pa 316L ndi 304 Stainless Steel

Onse316l ndi 304ndi zitsulo zosapanga dzimbiri za austenitic zomwe zimagwiritsidwa ntchito kwambiri m'mafakitale, zomangamanga, zamankhwala, ndi ntchito zokhudzana ndi chakudya. Komabe, amasiyana kwambirimankhwala, kukana dzimbiri, makina katundu, ndi ntchito.

1. Chemical Composition

304 Chitsulo chosapanga dzimbiri: Amapangidwa makamaka ndi18% chromium (Cr) ndi 8% nickel (Ni), chifukwa chake amadziwikanso kuti18-8 zitsulo zosapanga dzimbiri.

316L Chitsulo chosapanga dzimbiri: Muli16-18% chromium, 10-14% nickel, ndi zina2-3% molybdenum (Mo), zomwe zimawonjezera kukana kwake kwa dzimbiri.

The"L" mu 316Limayimirampweya wochepa (≤0.03%), kukonza weldability ake ndi kuchepetsa chiopsezo intergranular dzimbiri.

2. Kukanika kwa dzimbiri

304 ili ndi kukana bwino kwa dzimbiri, oyenera madera ambiri komanso kukhudzana ndi ma oxidizing acid.

316L imapereka kukana kwakukulu kwa dzimbiri, makamaka mumalo okhala ndi chloride(monga madzi a m'nyanja ndi mlengalenga wamchere), chifukwa cha molybdenum, yomwe imathandiza kukanakutsekeka kwa dzenje ndi dzimbiri.

3. Katundu Wamakina & Kugwira Ntchito

304 ndi wamphamvu, ndi kulimba kwapakati, kumapangitsa kuti ikhale yosavuta kuzizira, kupindika, ndi kuwotcherera.

316L ndi yocheperako pang'ono koma yocheperako, yokhala ndi mpweya wochepa wa carbon womwe umakhala bwinoweldability, kuzipanga kukhala zabwino kwa ntchito zomwe pambuyo pa weld kutentha mankhwala sizingatheke.

4. Kuyerekeza Mtengo

316L ndiyokwera mtengo kuposa 304, makamaka chifukwa cha kuchuluka kwake kwa nickel ndi molybdenum, zomwe zimawonjezera ndalama zopangira.

5. Ntchito Zofunikira

Mapeto

Ngati ntchito yanu ili mu achilengedwe chonse(monga ziwiya zakukhitchini, zomangira, kapena zida zapanyumba),304 ndi chisankho chotsika mtengo. Komabe, kwamalo owononga kwambiri(monga madzi a m'nyanja, kukonza mankhwala, kapena mankhwala) kapenakumene kuwotcherera kwapamwamba kumafunika, 316L ndiye njira yabwinoko.
