When selecting the right standards for the passivation of stainless steel, you might have come across two familiar acronyms – ASTM A967 and ASM 2700. Both are popular standards that are widely used across the industry. However, it is essential to understand the differences between these two standards to choose the right one for your process. This blog post will discuss ASTM A967 and ASM 2700 and how they differ.
Difference Between ASTM A967 and ASM 2700
One of the primary differences between ASTM A967 and ASM 2700 is cost. ASTM A967 is typically more expensive than ASM 2700 because it is a more technical standard.
Another difference between ASTM A967 and ASM 2700 is coverage. ASTM A967 covers a wider range of products than ASM 2700, including ferrous and non-ferrous metals. ASM 2700, on the other hand, only covers ferrous metals.
ASTM A967 and ASM 2700 also differ in terms of testing. ASTM A967 requires more extensive testing than ASM 2700 to ensure all products meet the necessary standards.
Finally, ASTM A967 and ASM 2700 differ in terms of certification. To be certified under ASTM A967, manufacturers must undergo a more rigorous process than those seeking certification under ASM 2700.
Choosing the right standard for the passivation of stainless steel is critical to ensure that the equipment is free from contamination and corrosion-resistant. As discussed in this blog post, ASTM A967 focuses on chemical passivation, while ASM 2700 is performance-based on cleanability. Careful consideration must be taken when selecting a standard, depending on the application, to ensure that all the right requirements are met. Understanding the differences between these two standards allows you to select the appropriate standard and ensure that your equipment meets the highest industry standards and regulations.
