Product Introduction

Non-Destructive Testing: Advanced non-destructive testing methods such as ultrasonic testing and eddy current testing are used to detect any internal defects in the raw materials .

Heat Treatment Monitoring: Since 321 stainless steel cannot be hardened by heat treatment, the heat treatment process is carefully monitored to ensure the material reaches the desired temperature range for optimal properties, typically between 950-1120°C .

Certification and Documentation: Comprehensive documentation and certification accompany each batch of raw materials, providing details of the chemical composition, mechanical properties, and test results .
