Chiyambi cha Russian Standard GOST 19281 09G2S

Muyezo waku Russia GOST-33259 09G2S ndi chitsulo chotsika cha alloy chomwe chimagwiritsidwa ntchito popanga zida zosiyanasiyana zamainjiniya ndi zomangamanga. Imakwaniritsa zofunikira za Russian national standard GOST 19281-89. 09G2S paChitsulo chili ndi mphamvu zambiri komanso kulimba, yoyenera kugwiritsa ntchito kutentha kwapakati pa -40 ° C mpaka +70 ° C.

Zofunika:

Kuchuluka kwa ntchito:

Chitsulo cha Russian 09G2S nthawi zambiri chimagwiritsidwa ntchito popanga mbale zachitsulo, mapaipi achitsulo ndi zida zachitsulo, monga nyumba, milatho, mapaipi amafuta, akasinja, zombo, ndi magalimoto. Kulimba kwake kwakukulu komanso kutsekemera kwabwino kumapangitsa kuti ikhale yoyenera ku engineering ya Structural yokhala ndi katundu wambiri wosasunthika, wosunthika komanso wogwedezeka.

Ubwino:

1. Mphamvu yayikulu: Chitsulo cha 09G2S chili ndi mphamvu zokhazikika komanso zopatsa mphamvu, zoyenerera ma projekiti a uinjiniya omwe ali ndi zofunikira zazikulu zamphamvu. 2. Weldability: Chitsulo cha 09G2S chili ndi weldability wabwino, zomwe zimapangitsa kuti zikhale zosavuta kuwotcherera ndi kugwirizanitsa ntchito. 3. Pulasitiki yabwino komanso yolimba: Chitsulo ichi chimakhala ndi pulasitiki yabwino komanso yolimba, yomwe imalola kuti ikhale yolimbana ndi zovuta zina zakunja ndi zowonongeka. 4. Kukana kwa dzimbiri: Chitsulo cha 09G2S chikhoza kukulitsa kukana kwake kwa dzimbiri kupyolera mu chithandizo cha kutentha kapena kupaka, ndikupangitsa kukhala koyenera kwa malo omwe amafunikira kukana kwa dzimbiri.

Zoyipa:

1. Mtengo wapamwamba: Poyerekeza ndi chitsulo chochepa cha carbon, 09G2S chitsulo chimakhala ndi mtengo wapamwamba, womwe ukhoza kuonjezera ndalama zopangira ntchito zazikulu. 2. Zomwe zili ndi alloy: Ngakhale kuti zitsulo za 09G2S ndizochepa, zimakhala zokwera pang'ono kusiyana ndi zitsulo zotsika kwambiri za carbon, zomwe zingachepetse ntchito zina zapadera.

Makhalidwe:

1. Mphamvu yapamwamba: Imakhala ndi mphamvu zokolola zambiri komanso mphamvu yokhazikika, ndipo imatha kupirira katundu waukulu ndi zovuta. 2. Kulimba kwabwino: kukhala ndi kulimba kwambiri komanso kulimba kwamphamvu, wokhoza kusunga magwiridwe antchito mokhazikika pansi pazambiri kapena kugwedezeka. 3. Kukana bwino kwa dzimbiri: Imakhala ndi kukana bwino kwa dzimbiri ndipo imatha kugwiritsidwa ntchito m'malo achinyezi komanso owononga. 4. Good processing performance: 09G2S zitsulo n'zosavuta kudula, kuwotcherera, ndi ozizira mapindikidwe, oyenera njira zosiyanasiyana processing. Nthawi zambiri, Russian muyezo 09G2S chitsulo ali ndi mphamvu mkulu, weldability wabwino ndi kulimba, ndi oyenera Structural engineering amafuna mphamvu mkulu ndi kukana dzimbiri.

Kufananiza

Zotsatirazi ndi zina zazitsulo zofanana ndi 09G2S, zomwe zingakhale ndi zofanana ndi 09G2S pakugwira ntchito ndikugwiritsa ntchito:

Q235B: Q235B ndi mpweya structural zitsulo mu Chinese muyezo GB/T 700-2006, amene ali weldability wabwino, processability ndi kulimba. Amagwiritsidwa ntchito kwambiri pomanga, milatho, kupanga makina ndi madera ena, ndipo ali ndi zofanana ndi 09G2S muzinthu zina za ntchito.

ASTM A36: ASTM A36 ndi chitsulo chopangidwa ndi mpweya mu American standard, chomwe chimakhala ndi zofanana ndi Q235B pakuchita. Amagwiritsidwa ntchito kwambiri popanga zigawo pomanga, kupanga ndi zina.

Chithunzi cha S235JRS235JR ndi chitsulo chopangidwa ndi mpweya mu EN 10025-2 European standard, yomwe ndi yofanana ndi Q235B ndi ASTM A36 pakugwira ntchito. Nthawi zambiri amagwiritsidwa ntchito pomanga, kupanga makina ndi zina.

A572 Kalasi 50: Ichi ndi chitsulo champhamvu chotsika kwambiri cha alloy mu American standard, chomwe chimakhala ndi weldability wabwino komanso kukana dzimbiri. Amagwiritsidwa ntchito kwambiri m'milatho, zomangamanga komanso kupanga makina olemera.

S355JR: S355JR ndi chitsulo chotsika kwambiri champhamvu kwambiri mu European standard EN 10025-2, chomwe chili choyenera kumanga, makina ndi mapaipi.

Zindikirani kuti ngakhale zitsulozi zimagawana zofanana ndi 09G2S potengera katundu ndi ntchito, pangakhale kusiyana kwa mankhwala enaake, makina opangidwa ndi makina opangira zinthu. Posankha chitsulo choyenera, tikulimbikitsidwa kuti mukhazikitse zosankha zanu pazofunikira zenizeni zaumisiri, zodziwika bwino komanso malingaliro a wopanga.
