Stainless Steel Passivation Services

At Del's Plating Works, we offer ASTM A380 and ASTM A967 stainless steel passivation that is designed to remove any foreign metals and oils from the surface, improving corrosion resistance without changing the dimension or appearance of the base metal. Our passivation services conform to QQ-P-35C, ASTM A967, ASTM A380, and AMS 2700 standards, ensuring the highest quality results.

QQ-P-35C passivation offers different types, each with its own temperature range and applications. For example, Type I is a low-temperature option, while Type III is a high-temperature option. ASTM A967 is the industry standard for chemical passivation treatments for stainless steel parts. Our passivation services also comply with ASTM A380, which establishes the minimum standard for cleaning and passivation of stainless steel parts. Additionally, we follow AMS 2700, which outlines the standards for passivation of corrosion-resistant steel parts.

• Type I - Low temperature.
• Type II - Medium temperature.
• Type III - High temperature.
• Type IV - For steels containing large amounts (0.15%) or sulfur or selenium.
• Type V - Anodic - For high carbon martensitic (440) steels.
• Type VI - Low temperature (optional)
