Post-Weld Heat Treatment	Optional	Inokurudzirwa kune zvakakosha majoini

Welding Kurudziro: Ye304H, Womic Steel inopa zanoER308H welding waya, ine chaiyo yekupisa yekupinza kutonga uye post-weld annealing yepamusoro-yakavimbika majoini mu-high-pressure piping systems.

 

6. Corrosion Resistance Comparison

Munzvimbo dzine chloride,304 ine yakakwirira gomba kuramba.

Iko kugona kwegomba kwe304H kuri kuda50mV yakaderera, zvichikonzera kurwiswa kwepakutanga kwenzvimbo.

Test Condition	304	304H
Cl⁻ Concentration 180ppm, 2 makore	No leakage	Perforation yakaonekwa
Gore negore Corrosion Rate (mm/gore)	~0.015 mm/gore	~0.020 mm/gore

Shandisa304munzvimbo dzinoda zvakanakisa general uye localized corrosion resistance sengeMarine cooling systems, kugadzira zvokudya, kanamakemikari matangi.

 

7. Kuedzwa uye Quality Certification
