Kuyerekeza Pakati pa 304H ndi 304 Mapaipi Azitsulo Zosapanga dzimbiri

- Womic Steel's Manufacturing Capabilities & Product Solutions

1. Mwachidule cha mankhwala

Womic Steel ndiwopanga mapaipi achitsulo osapanga dzimbiri, omwe amapereka onse awiri304Hndi304mapaipi zitsulo zosapanga dzimbiri malinga ndi mfundo zazikulu zapadziko lonse lapansi, kuphatikiza:

lASTM A312/A213/A269/A358

lASME SA312/SA213

lEN 10216-5 / EN 10297-2

lJIS G3459 / ISO 9329-4

lGB/T 14976/GB/T 13296

304H ndi 304 zonse ndi zitsulo zosapanga dzimbiri za austenitic, koma zidapangidwa kuti zizigwira ntchito mosiyanasiyana—304H imapambana mu ntchito yotentha kwambiri, pamene304 imapereka kukana kwakukulu kwa dzimbiri komanso kuwotchereramuzofuna zambiri.

2.Chemical Composition

 

Chinthu	304 Chitsulo chosapanga dzimbiri	304H Chitsulo chosapanga dzimbiri
Mpweya (C)	≤ 0.08%	0.04% - 0.10%
Chromium (Cr)	18.0% - 20.0%	18.0% - 20.0%
Nickel (Ndi)	8.0% - 11.0%	8.0% - 11.0%
Manganese (Mn)	≤ 2.00%	≤ 2.00%
Silicon (Si)	≤ 1.00%	≤ 1.00%
