Engineered for extreme corrosion resistance in aggressive chemical, pharmaceutical, and high-temperature processing environments.
How Southern Vietnam's booming chemical, semiconductor, agrochemical, and marine engineering sectors are driving demand for UNS R60702 non-ferrous metals.
Ho Chi Minh City, together with neighboring industrial corridors in Dong Nai and Ba Ria-Vung Tau, serves as the manufacturing backbone for Vietnam's fertilizer, agrochemical, pesticide, and organic acid synthesis industries. Zirconium 702 plates deliver zero corrosion rates in boiling hydrochloric acid (HCl), sulfuric acid, and acetic acid reaction columns.
With Saigon Hi-Tech Park (SHTP) attracting multi-billion-dollar semiconductor packaging, electronics assembly, and photovoltaic investments, ultra-pure Zirconium 702 sheets provide exceptional inertness for precision wet-bench etching tanks, high-purity chemical transfer lines, and vapor deposition fixtures.
Operating along the South China Sea maritime zone, petrochemical refineries and marine vessels linked through Cat Lai and Cai Mep-Thi Vai port complexes rely on Zirconium 702 clad plates and heat exchanger baffles to eliminate pitting, crevice corrosion, and stress cracking caused by hyper-saline seawater.
Over the past decade, Vietnam’s manufacturing sector has undergone a profound structural shift from basic assembly toward high-value chemical processing, precision tooling, clean energy equipment, and pharmaceutical production. Ho Chi Minh City stands at the center of this industrial modernization. As local equipment fabricators (EPC contractors, pressure vessel builders, and chemical equipment OEMs) in Thu Duc City, Tan Binh, Hiep Phuoc, and surrounding export processing zones upgrade their mechanical engineering standards, standard austenitic stainless steels (such as 316L) and basic duplex alloys frequently fail under severe mineral acid conditions.
This reality has triggered a steady and accelerating demand for commercially pure Zirconium 702 (UNS R60702) plates. Known for developing an instantaneous, self-healing, adherent zirconium oxide (ZrO₂) passive film upon air or moisture contact, Zirconium 702 demonstrates near-zero corrosion rates in boiling nitric acid, formic acid, acetic acid, urea production systems, and caustic chlorine compounds. As an established global manufacturer in China's "Titanium Valley" with specialized export channels directly servicing Ho Chi Minh City and Southern Vietnam, we provide certified, fully tested, and custom-cut Zirconium 702 plates tailored to strict project timelines.
Comprehensive chemical composition, physical properties, and corrosion performance metrics for mechanical engineers and plant designers in Vietnam.

Unlike conventional nickel alloys or super austenitic stainless steels, Zirconium 702 does not suffer from transgranular stress corrosion cracking (SCC) in chloride-rich environments, making it indispensable for tropical seaside chemical facilities in the Ho Chi Minh City – Vung Tau maritime perimeter.
