304 Icyuma Cyuma Cyuzuye

304 ibyuma bitagira umuyonga byerekana uruzitiro, rutunganijwe 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 ibyuma bitagira umuyonga (inkoni yumukara) bivuga ibyuma bizunguruka hejuru yumukara kandi bikabije, bishyushye cyane, byahimbwe, cyangwa bifatanye bidatunganijwe hejuru ya oxyde.

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 bitagira umuyonga 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 bitagira umuyonga ibyuma bigabanijwemo ubwoko butatu: kuzunguruka bishyushye, guhimba no gushushanya imbeho.Ibisobanuro bya hot-304 bishyushye bitagira ibyuma bizenguruka ni mm 5.5-130.Muri byo: 5.5-25mm ntoya 304 ibyuma bitagira ibyuma bitangwa cyane cyane bitangwa mumirongo igororotse, akenshi bikoreshwa nkibyuma, ibyuma nibice bitandukanye bya mashini;cyangwa mu buryo butaziguye mu ruziga, nkibicuruzwa byarangiye kugirango bisubirwemo nyuma.304 ibyuma bitagira umuyonga binini birenze mm 25 bikoreshwa cyane mugukora ibice bya mashini cyangwa gutobora ibyuma bitagira ibyuma.[2]

304 ibyuma bidafite ibyuma bizunguruka ibyuma biremereye:

Uburemere kuri metero (kg) = diameter * diameter * 0.00623
