In the world of high-performance manufacturing, the 304 Stainless Steel Salt Spray Test stands as the ultimate benchmark for validating material longevity. Grade 304, characterized by its 18% chromium and 8% nickel content, is the industry standard for corrosion resistance. However, without rigorous validation via accelerated simulation, the risk of "pitting corrosion" in saline environments remains a significant liability for global enterprises.
International buyers from North America, Europe, and the Middle East prioritize E-E-A-T (Expertise, Authoritativeness, Trustworthiness) when selecting factory partners. Procurement teams are moving away from "off-the-shelf" solutions toward custom environmental simulation ecosystems. This trend is driven by the need for compliance with ASTM B117, ISO 9227, and JIS Z 2371.
Over two decades of serving aerospace, automotive, and telecom leaders worldwide.
Strict adherence to international manufacturing and management protocols.
Leading the industry in simulation accuracy and energy-efficient chamber design.
As a premier China salt spray test factory, Dongguan Huanyi Instruments Technology Co., Ltd. leverages the massive industrial cluster of the Greater Bay Area. This allows for:
Dongguan Huanyi Instruments Technology Co., Ltd. was established on March 20, 2007, covering an area of 6,022 square meters. It is a high-tech enterprise integrating R&D, production, sales and after-sales service. It participated in the drafting of national standards and industry standards for environmental simulation test equipment.
Our philosophy is "customer-centric, quality-guaranteed, honesty-based, and innovation-oriented". Through unremitting efforts, Huanyi has cultivated a high-quality team with rich production, R&D and management experience.
Establishment of Dongguan Huanyi Instrument Technology.
Passed ISO 9001:2015 Quality Management certification.
Launched Guangdong Huance Testing Techology Co.Ltd Laboratory.
Ensuring your 304 Stainless Steel products meet specific regional regulatory demands is critical for market entry and brand protection.
Focus on ASTM B117 and ASTM G85 (Modified Salt Spray). We provide UL-certified electrical components for seamless factory integration.
Strict adherence to ISO 9227 (NSS, AASS, CASS) and CE marking requirements. Our chambers use eco-friendly refrigerants and low-energy heating arrays.
Full compliance with GB/T 10125 and GB/T 2423. Specialized testing for the EV (Electric Vehicle) battery housing industry using 304 SS.

High Quality Control from every aspect of raw material, production, installation, and commission. We utilize 304/316 grade stainless steel for critical components.
With more than 20 years of experience, we have professional production and R&D personnel. Huanyi can meet large-volume production orders at any time using ERP systems.
Our production includes laser cutting panels, ERP systems, and cutting automation. Our advanced equipment helps us reduce waste and improve precision.
ISO 9001 factory manufacturing. Mature technology and professional after-sales service with globally recognized brand components.
While 304 is corrosion-resistant, high concentrations of chloride ions can break down the protective "passive layer" (Chromium Oxide). Our tests help determine the exact saturation point for your material.
NSS (Neutral Salt Spray) is for standard metals. CASS (Copper-Accelerated Salt Spray) is much more aggressive and typically used for decorative coatings or high-durability alloys.
Yes. We specialize in walk-in chambers and customized dimensions (up to 30m³) for large-scale automotive lamp and interior component testing.
We use precision glass nozzles and a tower-based spray system that ensures uniform fall-out rates across the entire test area, preventing "hot spots" of corrosion.
Testing 5G base station housing durability.
Validating new alloy compositions.
In-line quality checks for fasteners.
Pre-shipment verification for global export.
Simulating sea freight corrosion conditions.
The main components of all company's products are made of internationally renowned brand components to ensure performance and reliability.
