Solution Heat Treatment

Solution heat treatment is a critical step in the production of Alloy 601 forged flanges. By precisely controlling heating temperatures and cooling rates, residual stresses from forging and machining are minimized, and microstructural stability is maintained.

Proper heat treatment ensures stable material performance for flanges exposed to high-temperature environments, making them suitable for applications such as industrial furnaces, high-temperature equipment, and heat treatment systems.

How Do We Control Quality at Every Stage of Production?

·Raw Material Inspection

MTSCO conducts incoming inspections for Alloy 601 raw materials, verifying material certificates, heat numbers, and material conditions. Tests such as PMI (Positive Material Identification) and chemical composition analysis are performed as required to confirm compliance with standards.

·Production Process Control

During manufacturing, the QC team monitors key production milestones, records production data via process cards, and inspects and documents critical processing steps.

·Final Inspection Before Shipment

After processing is complete, the product undergoes inspections for appearance, dimensions, sealing surfaces, and markings; testing such as PT (Dye Penetrant Testing) and UT (Ultrasonic Testing) is arranged according to order requirements. Relevant inspection records and packaging information are retained to facilitate subsequent product status verification by the customer.
