3. Oke oke na ụdị ngwaahịa
Womic Steel na-enye ọkpọkọ igwe anaghị agba nchara dị iche iche ahaziri maka ụlọ ọrụ mmepụta ihe, ụkpụrụ ụlọ na ngwa nrụgide:
Ọkụ na-enweghị ntụpọ:
Ogologo elu: 6mm - 610mm
Mgbidi ọkpụrụkpụ: 0.5mm - 50mm
Ọkụ welded (ERW / TIG / Laser):
Ogologo elu: 8mm - 1219mm
Mgbidi ọkpụrụkpụ: 0.5mm - 30mm
Nhọrọ ndị ọzọ:
Ọkụ ndị na-agbanwe ọkụ, ọkpọkọ U-ehulata, tubing a na-egbu maramara, na ọkpọkọ ahaziri mgbidi dị arọ.

| Isi ike (HBW) | ≤192 | ≤192 |
| Ike mgbawa (650 ℃, elekere 100,000) | ~ 55 MPa | ~ 80 MPa |
Isi Nghọta:
304H outperforms 304 n'okpuru ogologo oge elu okpomọkụ ọrụ (n'elu 550 ℃), na-eme ka ọ dị mma maka.ndị na-ekpo ọkụ ọkụ ọkụ, ndị na-eme mgbanwe petrochemical, na usoro nhazi okpomọkụ.
5. Ngwọta okpomọkụ na mkpa ịgbado ọkụ
| Oke | 304 | 304H |
| Ngwọta Annealing | 1010 - 1065 ℃ | ≥ 1080 ℃ |
| Nzaghachi ọrụ oyi | Magburu onwe | Ọnụ ọgụgụ na-arụ ọrụ siri ike |
| Weldability | Magburu onwe | Na-achọ ọla ndochi carbon dị elu |
| Ọgwụgwọ Okpomọkụ mgbe Weld gasịrị | Nhọrọ | Akwadoro maka nkwonkwo dị egwu |
Nkwanye ịgbado ọkụ: Maka 304H, Womic Steel na-atụ arowaya ịgbado ọkụ ER308H, na njikwa ntinye ọkụ ziri ezi na annealing post-weld maka nkwonkwo ntụkwasị obi dị elu na sistemụ ọkpọkọ dị elu.
6. Ntụnyere nguzogide nrụrụ aka
Na gburugburu ebe nwere chloride.304 nwere nguzogide olulu dị elu.
The pitting ike nke 304H bụ ihe50mV dị ala, na-eduga na mbuso agha mpaghara.
