Q345D yakaderera tembiricha inopikisa simbi pombi yemhando yekusimbisa
Yakanaka yakazara mechanicha zvivakwa, weldability, kutonhora uye kupisa kushanda uye kusagadzikana kwecorrosion, uye yakanaka yakaderera tembiricha kuoma.
Ngarava, boilers, midziyo yekumanikidza, matangi ekuchengetedza oiri, mabhiriji, chiteshi chemagetsi midziyo, kusimudza uye michina yekufambisa uye zvimwe zvakashongedzerwa zvimiro zvine mutoro wakakwira.
18nb yakaurayiwa simbi ine Nb, ine zvivakwa zvakafanana ne14MnNb, inonyanya kushandiswa ku cranes, blowers, makemikari michina, nezvimwe.
09mncupti atmospheric corrosion resistant simbi ine yakanaka yakaderera-tembiricha kukanganisa kuoma, weldability uye kutonhora uye kupisa kushanda. Inonyanya kushandiswa kune ese marudzi emuchina munzvimbo dzine hunyoro uye kunonaya uye inoora mamiriro ekunze
12mnv yakaderera tembiricha simbi ine tembiricha yekushanda ye - 70 ℃ inonyanya kushandiswa kune zvimiro zvemichina yefiriji inoshanda pakudziya kwakaderera.
14MnNb ine zvivakwa zvakafanana kune 18nb simbi uye inonyanya kushandiswa kumidziyo uye zvimwe zvikamu zvechimiro zvine tembiricha yekushanda ye - 20-450 ℃.
16Mn ine yakanaka yakazara mechanicha zvivakwa, yakaderera tembiricha kuita, kutonhora kutsika kuita, kuita welding uye machinability. Inonyanya kushandiswa mumigodhi, yekufambisa, makemikari indasitiri uye mamwe michina
Izvo zvimiro zve 16mnre zvakafanana ne16Mn simbi, kusimba kwesimba uye kutonhora kukotama zvivakwa zviri nani pane 16Mn, uye chinangwa chakafanana ne16Mn simbi.
Q345D simbi pombi chimwe chezvinhu zvesimbi pombi.

Q345A, Q345B, Q345C, Q345D uye Q345E ndiwo mamakisi emhando. Ivo vanowedzera kubva ku a kuenda ku e, kunyanya nekuda kwekusiyana kwekupisa tembiricha kunokonzerwa nezvakasiyana zvemukati ma microelements senge phosphorus nesarufa, inomiririra mutsauko wekukanganisa tembiricha uye michina zvimiro zvepombi kemikari.
Q345A, hapana kukanganisa; Q345B, 20 ° yakajairika tembiricha kukanganisa; Q345C, 0 dhigirii kukanganisa; Q345D, iri - 20 dhigirii kukanganisa; Q345E iri - 40 dhigirii kukanganisa. Pamhando dzakasiyana dzetembiricha, kukosha kwemaitiro kwakasiyanawo.
Q simba regoho harina kuderera kupfuura 345mp, uye giredhi yemhando inoratidza kuti ine zvinhu zvisina kuchena (carbon, manganese, silicon, sulfur uye phosphorus). Kuwanda kwetsvina (elements) musimbi. Iyo yakazotevera iyo A, B, C uye D, ishoma iyo isina kuchena yemukati
Q345A ine zvese phosphorus nesarufa isingasviki kana yakaenzana ne0.045%
Q345B ine zvese phosphorus nesarufa isingasviki kana yakaenzana ne0.040%
Q345C ine zvese phosphorus nesarufa isingasviki kana kuenzana ne0.035%
Q345D ine zvese phosphorus nesarufa isingasviki kana kuenzana ne0.030%
Q345E ine zvese phosphorus nesarufa isingasviki kana yakaenzana ne0.025%
Kunyanya kusvibiswa kwephosphorus nesarufa musimbi, ndiko kunowedzera kuoma kwesimba
Q345A -
Q345B Akv kwete pasi pe34 pa20 ℃
PaQ345C 0 ℃, Akv haifanire kunge iri pasi pe34
Q345D - Akv isiri pasi pe34 pa20 ℃
PaQ345E - 40 ℃, Akv haisi pasi pe27
