Ukuthelekisa phakathi kwe-304H kunye ne-304 yeMibhobho yeNtsimbi engagqwali

-Ubunakho bokuVelisa iWomic Steel kunye nezisombululo zeMveliso

1. Isishwankathelo seMveliso

I-Womic Steel ngumvelisi ohamba phambili we-premium-grade-grade mibhobho yentsimbi, enikezela zombini304Hkwaye304imibhobho yentsimbi engatyiwa ngokungqinelana nemigangatho emikhulu yamazwe ngamazwe, kuquka:

lASTM A312 / A213 / A269 / A358

lASME SA312 / SA213

lEN 10216-5 / EN 10297-2

lJIS G3459 / ISO 9329-4

lI-GB/T 14976 / GB/T 13296

I-304H kunye ne-304 zombini ziziintsimbi ze-austenitic stainless, kodwa zenzelwe iimeko ezahlukeneyo zokusebenza—I-304H iyagqwesa kwinkonzo yobushushu obuphezulu, ngelixaI-304 ibonelela ngokumelana nokugqwesa okuphezulu kunye ne-weldabilitykwizicelo zenjongo jikelele.

2.Ukuqulunqwa kwemichiza

 

Isiqalelo	304 Intsimbi engatyiwa	304H intsimbi engatyiwa
Ikhabhoni (C)	≤ 0.08%	0.04% - 0.10%
