Each flange follows a rigorous 8-step forging and quality-control process to ensure conformance with ASTM A182 and ASME standards.
Prime 304 stainless steel billet sourced and certified.
Heat to 1100°C – 1250°C for optimal forgeability.
Shape billet into flange geometry under controlled pressure.
Solution anneal at 1040°C – 1120°C, then quench.
CNC machining, drilling, and surface finishing.
Tensile, hardness, PMI, visual and impact tests performed.
