Introduction to Dipti Metal Industries' Expertise in ASTM A351 CG8M Valves
Dipti Metal Industries proudly stands as the largest global ASTM A351 CG8M Manufacturer in Mumbai, India, a premier A351 CG8M supplier in India, A351 CG8M stockist, A351 CG8M dealer, A351 CG8M distributor, and leading A351 CG8M exporter from India of Cast Austenitic Stainless Steel Valves. CG8M is the cast equivalent of Wrought 317 stainless steel. It is engineered for superior corrosion resistance over 316 (CF8M) due to its higher Molybdenum content (3.0% to 4.0%). Unlike the low-carbon CG3M, this grade has a standard carbon content (max 0.08%), meaning it requires post-weld solution annealing to restore full intergranular corrosion resistance in the heat-affected zones after welding.
We specialize in the manufacturing and supply of the entire ASTM A351 CG8M valve lineup, including CG8M Gate Valves (API 600), CG8M Globe Valves (API 623), CG8M Check Valves (API 594), and CG8M Ball Valves (API 6D/API 608). This material is chosen when the high corrosion resistance of 317 is needed, and either the part is not welded or post-weld solution annealing is feasible. Our valves consistently adhere to international dimensional and pressure-temperature standards, primarily ASME B16.34. Our extensive inventory makes us the biggest A351 CG8M Stockist in India, ready for prompt delivery to global chemical, pharmaceutical, and pulp & paper projects. Dipti Metal is your trusted A351 CG8M Valve Supplier in Mumbai for superior corrosion control and high-integrity service.
NOTE: For highly corrosive service with a requirement for field welding without post-weld heat treatment, consider the low-carbon version: ASTM A351 CG3M (Cast 317L) Valves. For standard 316 material, see our ASTM A351 CF8M (Cast 316) Valves.

ASTM A351 CG8M Valves — Frequently Asked Questions
CG8M (Cast 317) has a higher Molybdenum content (3.0% - 4.0% minimum) compared to CF8M (2.0% - 3.0%). This increased Molybdenum content provides superior resistance to pitting, crevice corrosion, and chemical attack in highly concentrated or severe acid environments.
The 'CG8M' is an austenitic chromium-nickel-molybdenum stainless steel casting grade. 'C' denotes Corrosion-resistant service, 'G' denotes a higher Nickel content, '8' is for standard carbon (max 0.08%), and 'M' stands for Molybdenum content, corresponding to Wrought 317 SS.
CG8M has a standard carbon content (max 0.08%) and is susceptible to weld sensitization (intergranular corrosion) if field welding is performed and post-weld solution annealing is not carried out. For weld-critical applications, the low-carbon version, CG3M (Cast 317L), is the preferred material.
CG8M valves are used in severe corrosive services such as Pulp & Paper, aggressive chemical processing, and high-chloride environments where its higher Molybdenum content is vital. It requires post-weld solution annealing for maximum corrosion resistance in the heat-affected zone.
