What Is ASTM A367 Cast Iron Chill?
According to ASTM A367, the methods for testing the chill characteristics of cast iron are established. The test measures the chill that forms as molten cast iron cools under specific conditions, which can be used to determine the cast iron’s ability to form hard, white structures known as white iron.
Chill tests are essential in the production of cast iron as the chilling can have a major effect on the machinability, hardness, and mechanical properties of the cast iron product.
Applications and Benefits of ASTM A367 Cast Iron Chill Testing
Scope
ASTM A367 is a test for determining the chill tendencies of cast iron by analyzing the depth and characteristics of the chilled areas that form during controlled conditions of casting. The test can help in understanding how iron composition and cooling rates affect white iron formation.
ASTM A367 evaluates:
● Chill depth formation in cast iron samples
● Tendency of cast iron to form white iron structures
● Influence of cooling conditions on cast iron microstructure
● Hardness variations within chilled regions
● Casting characteristics related to solidification behavior
Applications
● Cast iron foundry operations
● Engine blocks and automotive cast components
● Industrial machinery castings
● Pipe and fitting manufacturing
● Metallurgical research and alloy development
● Quality control of cast iron products
Benefits
● Helps control chill formation in cast iron castings
● Supports evaluation of casting composition and structure
● Assists in improving machinability of cast iron products
● Enables comparison of casting materials and processes
● Provides data for optimizing foundry production
Our ASTM A367 Testing Procedure
Sample Preparation
Molten cast iron is poured into a standardized chill test mold designed to produce controlled cooling conditions.
1Controlled Solidification
The metal solidifies in the mold, creating chilled regions depending on composition and cooling rate.
2Specimen Sectioning
The cast specimen is removed and sectioned to expose the chilled area for examination.
3Data Recording & Evaluation
The depth and characteristics of the chill zone are measured and analyzed according to the standard.

ASTM A367 Cast Iron Chill FAQs
ASTM A367 evaluates chill depth in cast iron by measuring the hardness and structure created during rapid solidification. This helps to determine how casting composition and cooling conditions affect hardness and microstructure.
Chill testing helps manufacturers see how cast iron reacts to quick cooling. This process ensures that castings reach the needed hardness, wear resistance, and machinability for industrial and mechanical uses.
ASTM A367 examines chill depth, hardness variation, and microstructural features created during casting. It offers insights into the solidification process and the performance of cast iron parts.
ASTM A367 is typically used for gray iron, ductile iron, and other cast iron alloys found in engine blocks, machine parts, and industrial castings.
ASTM A367 assesses chill characteristics in controlled casting conditions. It may not fully show the variations from different mold materials, cooling rates, or alloy compositions found in production settings.
