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 -
