304 Icyuma Cyuma Cyumuzingi

304 ibyuma bitagira umuyonga byerekana uruziga rworoshye, rutunganywa no kurangiza kuzunguruka, gukuramo cyangwa gushushanya bikonje; ikoreshwa kenshi mubikoresho bitandukanye bya shimi, ibiryo, imyenda nibindi bikoresho bya mashini hamwe nintego zimwe zo gushushanya. Ibyo bita 304 ibyuma bitagira umuyonga cyangwa 304 inkoni yicyuma (inkoni yumukara) bivuga ibyuma bizengurutse hejuru yumukara kandi bikabije, bishyushye cyane, byahimbwe, cyangwa bifatanye bidatunganijwe hejuru ya oxyde hejuru.

304: 18-8 ibyuma bidafite ingese, icyerekezo cya GB ni 0Cr18Ni9; Igipimo gisanzwe cyo muri Amerika: ASTM A276.

GB: C≤0.07; Si≤1.0; Mn≤2.0; P≤0.045; S≤0.03; Ni: 8.0-11.0; Cr: 17.0-19.0

ASTM: C≤0.08; Si≤1.0; Mn≤2.0; P≤0.045; S≤0.03; Ni: 8.0-11.0; Cr: 18.0-20.0

304 ibyuma bidafite ingese nicyuma gikoreshwa cyane na chromium-nikel ibyuma bitagira umuyonga, bifite imbaraga zo kurwanya ruswa, kurwanya ubushyuhe, imbaraga zubushyuhe buke hamwe nubukanishi. Irwanya ruswa mu kirere. Niba ari ikirere cyinganda cyangwa agace kanduye cyane, bigomba gusukurwa mugihe kugirango birinde ruswa. [1]

Ukurikije uburyo bwo gukora, ibyuma 304 bidafite ingese ibyuma bigabanijwemo ubwoko butatu: kuzunguruka bishyushye, guhimba no gushushanya imbeho. Ibisobanuro bya hot-304 bishyushye bitagira ibyuma bizenguruka ni 5.5-130 mm. Muri byo: 5.5-25mm ntoya 304 ibyuma bitagira umuyonga ibyuma bitangwa cyane cyane bitangwa mumirongo igororotse, akenshi bikoreshwa nkibyuma, ibyuma nibice bitandukanye bya mashini; cyangwa mu buryo butaziguye muri uruziga, nkibicuruzwa byarangiye kugirango bisubirwemo nyuma. 304 ibyuma bitagira umuyonga ibyuma birenga mm 25 bikoreshwa cyane mugukora ibice byubukanishi cyangwa gutobora ibyuma bitagira ibyuma.

304 ibyuma bidafite ibyuma bizengurutse ibyuma bireba:
