Heat treatment
Reading heat-treatment records for alloy fasteners
The specified condition, furnace cycle and test results should form one traceable production record.
Age-hardened and solution-treated alloys depend on controlled thermal processing to achieve the required condition. Purchase requirements should identify the governing specification and final material condition.
Heat-treatment records should connect the production lot to the furnace cycle and relevant mechanical or hardness results. Any project-specific hold points should be agreed before processing begins.
