316 / 316L Mirija ya Chuma cha pua Isiyo na Mfumo
Utangulizi wa Bidhaa
Aina 316/316L ni nikeli ya chromium austenitic chuma cha pua kilicho na molybdenum. Nyongeza ya molybdenum huongeza upinzani wa kutu kuliko ile ya 304/304L katika mazingira ya halidi na pia katika kupunguza asidi kama vile asidi ya sulfuriki na fosforasi. Aina ya 316L inaweza kuthibitishwa kuwa 316 wakati muundo unafikia kikomo cha chini cha kaboni cha 316L na viwango vya juu kidogo vya nguvu vya 316. Aina ya 316L inapaswa kubainishwa kwa programu zilizochochewa kwani toleo la kaboni ya chini huondoa mvua ya chromium carbudi na kuongeza upinzani wa kutu katika hali kama-svetsade.
Aina ya 316/316L hustahimili kutu ya angahewa na pia katika mazingira ya kiasi cha vioksidishaji. Pia hupinga kutu katika anga za baharini na ina upinzani bora kwa kutu ya intergranular katika hali ya svetsade. Aina 316/316L ina nguvu bora na uimara katika halijoto ya cryogenic. Aina ya 316/316L haina sumaku katika hali ya kuchujwa lakini inaweza kuwa sumaku kidogo kutokana na kufanya kazi kwa baridi kali.
Daraja la 316L, toleo la kaboni ya chini la 316 na lina kinga ya juu sana kutokana na uhamasishaji (mvua ya CARBIDE ya mpaka wa nafaka). Inatumika sana katika tasnia ya mafuta na gesi na kemikali kwa upinzani wake wa kutu wa gharama na urahisi wa utengenezaji. Kwa kawaida hakuna tofauti ya bei inayokubalika kati ya 316 na 316L chuma cha pua. Muundo wa austenitic pia huwapa darasa hizi ushupavu bora, hata chini ya joto la cryogenic. Ikilinganishwa na vyuma vya chromiumnickel austenitic, chuma cha pua cha 316L hutoa mteremko wa juu zaidi, mkazo wa kupasuka na nguvu ya kustahimili joto la juu.
