Mortec Manufacturing Co works as a direct Stainless Steel 410 Flanges Manufacturer in India. We closed-die forge ASTM A182 F6a blanks from heat-numbered UNS S41000 bar. All forging takes place inside our own Mumbai manufacturing units. Because 410 is martensitic chromium steel, heat treatment determines performance. Each lot receives Class 1 annealed or Class 2 treatment. Class 2 material is hardened and tempered before CNC machining. Actual measured hardness appears on certificates rather than copied templates.
Finish machining follows ASME B16.5, B16.47 Series A and B, or MSS. We manufacture Lap Joint Flanges with accurate stub-end mating radii. Available types include weld neck, blind, slip-on, socket weld, and orifice. Plate, reducing, and spectacle blind flanges are also manufactured. Standard pressure classes range from Class 150 through Class 2500. Custom bores, drilling, and outside diameters follow your approved isometric. Every Mumbai dispatch includes PMI readings and detailed hardness reports. EN 10204 3.1 or 3.2 certificates accompany every shipment file.
Everything below is confirmed in writing on your order acknowledgement before the first billet is cut.
