Pehea e hoʻokaʻawale pololei ai ʻo XRF i nā papa kila kila 321 a me 347?
ʻO ka ʻokoʻa ma waena o ke kila kila 321 a me 347 e hilinaʻi ana i ka ʻike ʻana i ka nui o ka titanium a me ka niobium. Ua like like nā papa ʻelua, a ʻo ka ʻike hewa ʻana e hoʻonui i ka pilikia o ka corrosion intergranular ma hope o ka hoʻoheheʻe ʻana. No ka laʻana, ʻo ka hoʻohana ʻana i ka 321 ma kahi o 347 i ka mahana kiʻekiʻe...E heluhelu hou aku -
Hiki i nā Spectro XRF Analyzers ke hoʻokaʻawale i waena o 410 a me 430 Stainless Steel?
Loaʻa i ke kila kila 410 he 11.5–13.5% chromium a hiki i ka 0.15% kalapona. ʻO kona kalapona kiʻekiʻe e ʻae i ka paʻakikī ma o ka mālama wela, e hoʻomaikaʻi ana i ke kūpaʻa ʻana a me ka ikaika. Loaʻa i ke kila kila 430 he 16–18% chromium me ka nui o 0.12% kalapona. Hoʻonui kēia i ka chromium e...E heluhelu hou aku -
Pehea e hoʻomaʻalahi ai ka mea loiloi mea XRF i ka ʻike ʻana i ke kila kila 201 vs 304
ʻO ke kila kila 304 he 18–20% chromium, 8–10.5% nickel, a emi ma mua o 2% manganese. ʻO ke kila kila 201 he 16–18% chromium, 3.5–5.5% nickel, a he 5–7.5% manganese kiʻekiʻe. ʻOi aku ke kiʻekiʻe o ka naikokene ma 201 (a hiki i ka 0.25%) e hoʻohālikelike ʻia me 304 (a hiki i ka 0.10%). ʻO ke nickel kiʻekiʻe ma 304 enab...E heluhelu hou aku -

ʻO ke kila kila 316 a me ke kila kila 316L he austenitic, me nā pae like o ka chromium (16-18%), nickel (10-14%), a me ka molybdenum kiʻekiʻe (2-3%). ʻO ka ʻokoʻa nui ka ʻike kalapona o 316L ma lalo o 0.03%, e kūʻē i ka 0.08% kiʻekiʻe no 316. ʻO ke kalapona haʻahaʻa he ʻulaʻula nui...E heluhelu hou aku -
Pehea e hōʻoia ai nā mea loiloi XRF i nā kila kila 304, 316, a me 321
ʻO ka kuhi hewa ʻana i ka 316 ma ke ʻano he kila kila 304 e hōʻemi ana i ke kūpaʻa ʻana i ka pala. Hoʻoweliweli kēia hewa i nā lako i loko o nā hale hana kai, petrochemical, a me nā meaʻai, e hiki ai ke hōʻeha a me ka hōʻeha nui. ʻO ka hiki ʻole ke hahai pono i nā mea ke hopena i ka hoʻokō ʻana...E heluhelu hou aku -
Pehea e hoʻoholo ai i ka haku mele ʻana o nā mea hoʻohuihui nickel?
ʻO nā metala i hoʻokumu ʻia i ka nickel he mau metala i hana ʻia me ka nickel ma ke ʻano he mea nui, ʻoi aku ka nui ma mua o 50% ma ke kaumaha. ʻO kā lākou microstructure e hiki ai i ka ikaika mechanical kūikawā, ke kūpaʻa kolo, a me ke kūpaʻa oxidation a hiki i 800°C. ʻO kēia mau waiwai e hana ai i nā allo i hoʻokumu ʻia i ka nickel...E heluhelu hou aku -
Pehea e ʻike pono ai i ka kila Cr-V wahaheʻe i ka wā e loaʻa ai ka nānā ʻana me ka XRF lima?
Pono ke kila chromium vanadium i ka hoʻohuihui pololei no ka ikaika kiʻekiʻe a me ke kūpaʻa luhi. Hoʻohana ka hapa nui o nā kila mea hana i ka chromium 0.5-1% a me ka vanadium 0.15-0.25%.
