Armoloy Specifications

What is AMS 2438?

AMS 2438 is a well-recognized industry standard developed by SAE International that outlines key expectations for thin dense chrome plating. Though originally intended for aerospace applications, it has become a benchmark across industries where surface durability, wear resistance, and coating precision are critical. While the full specification must be obtained through SAE, many manufacturers align their plating practices with its intent to support high-performance outcomes and regulatory compliance.

At Armoloy, we apply internal processes that reflect the spirit of AMS 2438 — including consistent coating thickness, strong adhesion, and enhanced protection against corrosion and wear. Referencing AMS 2438 helps customers identify trusted plating solutions that meet demanding industry expectations. For full technical requirements, users should consult the official specification directly from SAE International.

AMS 2438 Testing Methodology & Results

To align with the performance goals of AMS 2438, Armoloy applies rigorous internal testing protocols that typically include hardness, adhesion, corrosion resistance, abrasion resistance, and hydrogen embrittlement resistance. These tests help ensure our coatings meet industry expectations for durability and precision. For full test requirements, consult the official AMS 2438 specification from SAE International.

Hardness Test: Measures resistance to deformation under pressure using microhardness testing techniques, ensuring it can withstand mechanical stress.
Adhesion Test: Confirms strong bonding to the substrate to prevent delamination or failure.
Corrosion Resistance Test: Assesses protection against harsh environments using salt fog or porosity tests.
Abrasion Resistance Test: Evaluates wear resistance through methods like the Taber Abrasion Test.
Hydrogen Embrittlement Test: Ensures the component resists brittleness caused by hydrogen absorption.

AMS 2438 upholds strict quality assurance through sampling, periodic testing, and precise documentation to maintain consistent plating performance.
