ASTM A967 and ASTM A380 Passivation Services
When engineers design critical components for demanding environments, specifying the correct surface treatment is vital for long term performance. At Electro-Max, we provide certified ASTM A967 and ASTM A380 passivation services to ensure your parts are thoroughly cleaned and protected against corrosion. Our facility is equipped to handle complex geometries and tight tolerances, guaranteeing that every piece receives the precise chemical treatment required by your blueprints. Whether you are passivating stainless steel or need to passivate highly specialized austenitic alloys, our team delivers the documentation and quality control necessary to meet strict regulatory compliance.
Certified Passivation for Stainless Steel Components
Removing free iron and surface contaminants is the most important step in preventing premature oxidation on manufactured parts. While stainless steel is naturally resistant to rust, the machining and fabrication processes often embed trace metals into the surface. Our chemical baths dissolve these impurities and accelerate the formation of a protective chromium oxide layer. By adhering to recognized passivation quality standards, we help you extend the lifecycle of your components and prevent costly equipment failures in the field.
Understanding ASTM A967 and ASTM A380 Standards
While both specifications aim to improve the corrosion resistance of metal surfaces, they serve slightly different purposes in the finishing process. We perform both services at our facility to ensure your components meet the exact testing and processing requirements of your industry.
ASTM A967 Specifications
This standard focuses specifically on the chemical passivation treatments for stainless steel parts. It details the precise temperature, time, and concentration requirements for both citric acid and nitric acid baths. It also establishes the accepted testing methods used to verify that the surface is free of iron contaminants after the process is complete.
ASTM A380 Specifications
This broader specification serves as the foundational guide for cleaning, descaling, and passivating stainless steel parts. It outlines the acceptable methods for removing heavy scale, grease, and machining fluids prior to the final chemical treatment. Following this standard ensures that the metal surface is completely free of organic and inorganic soils that could interfere with the oxide layer formation.
Selecting the Correct Standard
Engineers often specify both standards on drawing requirements to ensure a part is properly cleaned before it is chemically treated. Our finishing experts review every order to determine the correct acid concentrations and bath times required to achieve compliance without compromising the dimensional integrity of your parts.
Industries Relying on ASTM A967 and ASTM A380 Certified Passivation
Manufacturers producing mission critical components rely on strict compliance to ensure end user safety. The A967 and A380 standards are predominantly required in environments where surface hygiene and catastrophic part failure are major concerns. We provide certified metal finishing services for businesses operating in these highly regulated fields, including:
- Aerospace and defense contractors
- Medical device manufacturing
- Food and beverage processing facilities
- Pharmaceuticals and bio-processing

The primary distinction is their scope. The A380 standard covers the entire cleaning, descaling, and preparation process for stainless steel parts. The A967 standard focuses exclusively on the chemical passivation treatments (like citric or nitric acid baths) and the subsequent testing methods used to verify a clean surface.
Yes. Our facility is equipped to process a wide variety of materials. We carefully adjust our bath concentrations, temperatures, and immersion times to safely treat 300 series metals and specialized austenitic alloys without causing etching or dimensional changes.
The required standard is typically called out directly on the engineering blueprint or part drawing provided by the original equipment manufacturer. If your drawing simply calls for "passivation" without listing a standard, our team can help you determine the most appropriate treatment based on the material grade and the end use of the component.
