PED Approved ASTM B348 Gr 7 Hex Bolt manufacturer in India with Certified Quality Assurance
Mortec Manufacturing Co forges every Titanium Grade 7 flange carefully. Each flange comes directly from traceable UNS R52400 billet stock. Every blank carries its heat number before reaching CNC lines. Grade 7 is commercially pure titanium with small palladium addition. That palladium shifts metal into passive range inside reducing acids. This result creates a flange surviving hot hydrochloric and sulphuric. Machining runs to ASME B16 5 and B16 47 standards. Precision work happens in our own modern Mumbai units daily. We offer RF and RTJ facing with smooth finish options. Custom bore drilling is available to match your exact isometric drawings. Working direct lets us skip the intermediate trading layer completely. Weld Neck Slip On Blind Socket Weld and Threaded types move. All flange types move easily from Class 150 through 2500. Every single dispatch carries PMI reports and EN mill certs.
