ERNiCr-3 UNS N06082/W. Nambari 2.4806 waya ya kulehemu ya aloi ya nikeli

Muhtasari

ERNiCr-3 ni aina ya waya ya nickel-chromium-molybdenum msingi wa aloi ya kulehemu. Aina hii ya waya wa kulehemu ina sifa nzuri za mitambo, upinzani mkali wa kutu, upinzani wa oxidation, na nguvu ya juu ya kutambaa. Katika mchakato wa kulehemu, ina arc imara, malezi mazuri ya weld, mtiririko mzuri wa chuma cha moto, hivyo ina utendaji bora wa mchakato wa kulehemu.

Matumizi kuu ya waya za kulehemu za ERNiCr-3 ni kulehemu kwa aloi za nickel-chromium-molybdenum, kama vile Inconel600, 601 na aloi za Incoloy800, pia zinaweza kutumika kwa kulehemu kwa aloi hizi na chuma cha kaboni, chuma cha pua na vifaa vingine tofauti. pamoja na kulehemu uso. Kwa kuongezea, kwa sababu ya upinzani wake mzuri wa kutu, ERNiCr-3 pia hutumiwa sana kwa kulehemu katika mazingira yaliyo na klorini kama vile mimea ya kuondoa chumvi.

Upinzani wa kutu

Waya ya kulehemu ya ERNiCr-3 ina upinzani bora wa kutu. Hii ni hasa kutokana na uwiano wake wa juu wa vipengele vya nickel na chromium. Nickel ina upinzani mzuri wa kutu na inaweza kupinga mmomonyoko wa asidi, alkali, chumvi na vyombo vingine vya habari. Chromium inaweza kutengeneza filamu mnene ya oksidi juu ya uso wa aloi, ikizuia kwa njia babuzi kuingilia ndani ya nyenzo, na hivyo kulinda nyenzo kutokana na kutu.

Kwa hivyo waya wa kulehemu wa ERNiCr-3 ni thabiti katika mazingira anuwai ya kutu, kama vile mazingira ya tindikali, alkali na chumvi. Hii huifanya kuwa bora kwa nyenzo za kulehemu kama vile chuma cha aloi ya juu, chuma cha pua, aloi zenye nikeli, na aloi zingine zinazostahimili kutu ikiwa ni pamoja na zirconium, tungsten, cobalt na tantalum.
