• Duplex SS - nikel yo hejuru na molybdenum - 2205, 2003, 2404
• Super Duplex - 25Chromium na nikel yo hejuru na molybdenum “plus” - 2507, 255 na Z100
• Hyper Duplex - Cr, Ni, Mo na N - 2707

Ibikoresho bya mashini:
• Duplex Stainless Steel ifite hafi inshuro ebyiri imbaraga zumusaruro wa mugenzi wabo austenitis.
• Ibi bituma abashushanya ibikoresho bakoresha ibikoresho byoroheje byo kubaka ubwato!

Duplex idafite ibyuma byiza:
1. Ugereranije nicyuma cya austenitis
1) Imbaraga zumusaruro zirenze inshuro ebyiri kurenza ibyuma bisanzwe bya austenitike, kandi bifite ubukana bwa plastike buhagije bukenewe kugirango bibumbwe.Ubunini bwikigega cyangwa icyombo cyumuvuduko gikozwe mubyuma bya duplex bitagira ibyuma biri munsi ya 30-50% ugereranije nicyuma gikoreshwa cyane na austenitis ibyuma bidafite ingese, bifite akamaro mukugabanya igiciro.
)Kwangirika kwa Stress nikibazo gikomeye icyuma gisanzwe cya austenitis kitagira ibyuma bigoye kugikemura.
3) Ibyuma bisanzwe 2205 duplex idafite ibyuma bikoreshwa mubitangazamakuru byinshi bifite imbaraga zo kurwanya ruswa kurusha ibyuma bisanzwe 316L bya austenitis bitagira ibyuma, mugihe ibyuma bya super duplex bitagira ibyuma bifite imbaraga zo kurwanya ruswa.Mu bitangazamakuru bimwe, nka acide acetike na aside aside.Irashobora no gusimbuza ibyuma-binini cyane bya austenitike ibyuma bitagira umuyonga ndetse n’ibishobora kwangirika.
4) Ifite imbaraga zo kurwanya ruswa.Ugereranije nicyuma cya austenitike kitagira ibyuma kimwe, gifite uburyo bwiza bwo kwambara no kurwanya umunaniro wa ruswa kuruta ibyuma bya austenitike.
5) Ibyuma bya austenitis bitagira umuyonga bifite coefficient nkeya yo kwagura umurongo kandi byegereye ibyuma bya karubone.Irakwiriye guhuza ibyuma bya karubone kandi bifite akamaro gakomeye mubuhanga, nko gukora plaque compte cyangwa imirongo.

2. Ugereranije nicyuma cya ferritic, ibyuma bya duplex ibyuma bidafite ibyuma nibi bikurikira:
1) Ibikoresho byose byubukanishi birarenze ibyibyuma bya ferritic bidafite ibyuma, cyane cyane ubukana bwa plastiki.Ntabwo yunvikana kuburiganya nkicyuma cya ferritic.
2) Usibye guhangayikishwa no kwangirika kwangirika, ibindi birwanya ruswa biruta ibyuma bya ferritic.
3) Imikorere ikonje ikora nuburyo bukonje bukonje nibyiza cyane kuruta ferritic stainless ibyuma.
4) Imikorere yo gusudira ni nziza cyane kuruta iy'icyuma cya ferritic.Mubisanzwe, nta kuvura ubushyuhe bisabwa nyuma yo gushyushya nta gusudira.
5) Urutonde rwo gusaba ni rugari kuruta icyuma cya ferritic.

GusabaBitewe nimbaraga nyinshi zicyuma cya duplex, ikunda kubika ibikoresho, nko kugabanya uburebure bwurukuta rwumuyoboro.Gukoresha SAF2205 na SAF2507W nkurugero.SAF2205 irakwiriye gukoreshwa mubidukikije birimo chlorine kandi birakwiriye gukoreshwa munganda cyangwa mubindi bitangazamakuru bivangwa na chloride.SAF 2205 irakwiriye cyane cyane gukoreshwa muguhindura ubushyuhe burimo chlorine y'amazi cyangwa amazi meza nkuburyo bukonjesha.Ibikoresho birakwiriye kandi kuvangwa na acide sulfurike ya acide na acide organic organique hamwe nuruvange rwayo.Nka: imiyoboro ya peteroli mu nganda za peteroli na gaze: kuvanaho amavuta ya peteroli mu nganda, kweza imyuka irimo sulfuru, ibikoresho byo gutunganya amazi mabi;sisitemu yo gukonjesha ukoresheje amazi meza cyangwa chlorine irimo ibisubizo.

Kwipimisha Ibikoresho:
SAKY STEEL menya neza ko ibikoresho byacu byose binyura mubizamini byubuziranenge mbere yo kubohereza kubakiriya bacu.

• Kwipimisha Kumashini nka Tensile yakarere
Ikizamini gikomeye
Isesengura ryimiti - Isesengura rya Spectro
• Kumenyekanisha ibikoresho byiza - Ikizamini cya PMI
Ikizamini cya Flattening
• Micro na MacroTest
• Gukora Ikizamini cyo Kurwanya
Ikizamini cyo gutwika
• Ikizamini cya ruswa hagati (IGC)
