Yintoni Eyenza I-304 vs 316 Ithandwe Kangaka?
Amanqanaba aphezulu e-chromium kunye ne-nickel afumaneka kwi-304 kunye ne-316 stainless steel abenza bakwazi ukumelana nobushushu, ukukrala, kunye nokugqwala. Abaziwa nje kuphela ngokuxhathisa ukugqwala, kodwa baziwa nangokubonakala kwabo kucocekile kunye nokucoceka ngokubanzi.
Zombini ezi ntlobo zentsimbi engagqwaliyo zivela kumashishini ahlukeneyo. Njengolona hlobo luqhelekileyo lwentsimbi engagqwaliyo, i-304 ithathwa njengentsimbi engagqwaliyo eqhelekileyo "18/8". Intsimbi engagqwaliyo ye-304 isetyenziswa kakhulu kuba ihlala ixesha elide kwaye kulula ukuyila kwiindlela ezahlukeneyo ezifana nephepha lentsimbi engagqwaliyo, ipleyiti yentsimbi engagqwaliyo, ibha yentsimbi engagqwaliyo, kunye netyhubhu yentsimbi engagqwaliyo. Ukumelana kwentsimbi ye-316 kwiikhemikhali nakwiindawo zaselwandle kwenza ukuba ibe lukhetho oludumileyo phakathi kwabavelisi.
Zihlulwe njani ngokweendidi?
Iindidi ezintlanu zentsimbi engagqwaliyo zihlelwe ngokwesakhiwo sazo sekristale (indlela ezihlelwe ngayo iiathom zazo). Kwiindidi ezintlanu, intsimbi engagqwaliyo engama-304 kunye ne-316 zikwiklasi ye-austenitic grade. Ulwakhiwo lweentsimbi ezingagqwaliyo ze-austenitic grade luzenza zingabi namandla kwaye luzithintele ekubeni ziqine ngonyango lobushushu.

Intsimbi Engagqwaliyo engama-304 vs 316: Ukumelana nobushushu
Ukumelana nobushushu yinto ebalulekileyo ekufuneka iqwalaselwe xa kuthelekiswa amanqanaba ahlukeneyo entsimbi engatyiwayo. Ububanzi bokunyibilika obuyi-304 bumalunga nama-50 ukuya kwi-100 degrees Fahrenheit ngaphezulu kwama-316. Nangona ububanzi bokunyibilika obuyi-304 bungaphezulu kwama-316, zombini zinokumelana okuhle ne-oxidization kwinkonzo eqhubekayo ukuya kuthi ga kwi-870°C (1500℉) nakwinkonzo eqhubekayo kwi-925°C (1697℉).
304 SS: Iphatha ubushushu obuphezulu kakuhle, kodwa ukusetyenziswa rhoqo kwi-425-860 °C (797-1580 °F) kunokubangela ukugqwala.
316 SS: Isebenza kakuhle kumaqondo obushushu angaphezulu kwe-843 ℃ (1550 ℉) nangaphantsi kwe-454 ℃ (850°F)
Umahluko wexabiso phakathi kwe-304 Stainless Steel vs 316
Yintoni eyenza i-316 ibize kakhulu kune-304 stainless steel?
Ukwanda komxholo we-nickel kunye nokongezwa kwe-molybdenum kwi-316 kwenza ukuba ibize kakhulu kune-304. Ngokomyinge, ixabiso le-316 stainless steel liphezulu ngama-40% kunexabiso le-304 SS.
Intsimbi Engagqwaliyo engama-316 vs 304: Yeyiphi engcono?
Xa kuthelekiswa i-304 stainless steel vs 316, zombini zinezibonelelo kunye neengxaki ekufuneka ziqwalaselwe xa kusenziwa isigqibo sokuba zeziphi ekufuneka zisetyenziswe kwiindlela ezahlukeneyo. Umzekelo, i-316 stainless steel inokumelana netyuwa kunye nezinye izinto ezibolayo kune-304. Ngoko ke, ukuba wenza imveliso edla ngokuchatshazelwa ziikhemikhali okanye yimeko-bume yolwandle, i-316 lolona khetho lungcono.
Kwelinye icala, ukuba wenza imveliso engadingi kuxhathisa ukugqwala ngamandla, i-304 lukhetho olusebenzisekayo nolungabizi kakhulu. Kwiinkqubo ezininzi, i-304 kunye ne-316 ziyatshintshana.
