Introduction to Dipti Metal Industries' Expertise in ASTM A351 CG3M Valves
Dipti Metal Industries proudly stands as the largest global ASTM A351 CG3M Manufacturer in Mumbai, India, a premier A351 CG3M supplier in India, A351 CG3M stockist, A351 CG3M dealer, A351 CG3M distributor, and leading A351 CG3M exporter from India of Cast Austenitic Stainless Steel Valves. CG3M is the cast equivalent of Wrought 317L stainless steel. It is specifically engineered for maximum corrosion resistance in highly aggressive environments, providing a superior option to standard 316L (CF3M). The critical difference is its higher Molybdenum content (3.0% to 4.0%) combined with a low carbon content (max 0.03%), which prevents intergranular corrosion after welding (sensitization) while maximizing resistance to localized attack.
We specialize in the manufacturing and supply of the entire ASTM A351 CG3M valve lineup, including CG3M Gate Valves (API 600), CG3M Globe Valves (API 623), CG3M Check Valves (API 594), and CG3M Ball Valves (API 6D/API 608). This material's exceptional chemical resistance makes it indispensable in sectors dealing with hot, corrosive agents. Our valves consistently adhere to international dimensional and pressure-temperature standards, primarily ASME B16.34. Our extensive inventory makes us the biggest A351 CG3M Stockist in India, ready for prompt delivery to global chemical, pharmaceutical, and pulp & paper projects. Dipti Metal is your trusted A351 CG3M Valve Supplier in Mumbai for maximum corrosion control and high-integrity service.
NOTE: For applications with even higher service temperature demands, consider our Niobium-stabilized grades like ASTM A351 CF8C (Cast 347) Valves, or for a more cost-effective standard 316L option, see our ASTM A351 CF3M (Cast 316L) Valves.

ASTM A351 CG3M Valves — Frequently Asked Questions
CG3M (Cast 317L) has a higher Molybdenum content (3.0% - 4.0% minimum) compared to CF3M (2.0% - 3.0%). This increased Molybdenum and Chromium content provides significantly superior resistance to pitting, crevice corrosion, and chemical attack in highly concentrated or severe acid environments.
The 'CG3M' is an austenitic chromium-nickel-molybdenum stainless steel casting grade. 'C' denotes Corrosion-resistant service, 'G' denotes a higher Nickel content, '3' is for low carbon (L-grade, max 0.03%), and 'M' stands for Molybdenum content, corresponding to Wrought 317L SS.
Yes, CG3M is a low-carbon (L-grade) alloy with a maximum carbon content of 0.03%. This makes it resistant to intergranular corrosion (weld sensitization) and highly suitable for welded assemblies where post-weld solution annealing is impractical, combining superior chemical resistance with excellent weldability.
CG3M valves are primarily used in severe corrosive environments such as Pulp & Paper (bleaching chemicals), highly aggressive chemical processing, high-chloride environments, and any application requiring enhanced resistance to concentrated sulfuric or phosphoric acids.
