As an A217 WC6 Valve Manufacturer in Mumbai and global leader, we ensure exceptional quality and material compliance from Mumbai, India.
Introduction to Dipti Metal Industries' Expertise in ASTM A217 WC6 Valves
Dipti Metal Industries proudly stands as the largest global ASTM A217 WC6 Manufacturer in Mumbai, India, a premier A217 WC6 supplier in India, A217 WC6 stockist, A217 WC6 dealer, A217 WC6 distributor, and leading A217 WC6 exporter from India of Cast Chromium-Molybdenum (Cr-Mo) Steel Valves. This low alloy steel material, specified as WC6 (1.25% Cr, 0.5% Mo), is the industry standard for general-purpose valves in high-temperature, high-pressure steam and hot oil service, where standard carbon steel (like WCB) loses its strength due to creep and risk of graphitization above 425°C. The WC6 grade is chemically balanced to ensure superior creep strength and structural integrity for critical pressure-retaining parts.
We specialize in the manufacturing and supply of the entire ASTM A217 WC6 valve lineup, including WC6 Gate Valves (for isolation in accordance with API 600), WC6 Globe Valves (for flow regulation/throttling per API 623), and WC6 Check Valves (for backflow prevention per API 594). Our products rigorously adhere to dimensional and pressure-temperature standards, primarily ASME B16.34. Our extensive inventory makes us the biggest A217 WC6 Stockist in India, capable of immediate dispatch to meet urgent project requirements globally, especially for power plant outages. Dipti Metal is your trusted A217 WC6 Valve Supplier in Mumbai for high-specification industrial projects operating under elevated temperatures.
NOTE: For applications requiring even higher temperatures or greater thermal cycling, consider our ASTM A217 WC9 (2.25% Cr-1% Mo) Valves, or for general carbon steel use, see our Carbon Steel WCB Valves.

ASTM A217 WC6 Valves — Frequently Asked Questions
ASTM A217 WC6 is a Cast Chromium-Molybdenum (Cr-Mo) Low Alloy Steel used primarily for high-pressure, high-temperature service (like superheated steam and hot oil). It is specifically suitable for temperatures from -29°C (-20°F) up to 593°C (1100°F).
The 'WC6' in ASTM A217 WC6 is a low alloy steel casting grade containing 1.00% to 1.25% Chromium and 0.45% to 0.65% Molybdenum. This composition is engineered to provide excellent creep strength and prevent graphitization, maintaining material integrity in high-heat applications like steam power plants.
WCB (Carbon Steel) rapidly loses strength above 425°C and is prone to graphitization. WC6's Chromium and Molybdenum content prevents these issues, ensuring the valve body maintains its mechanical strength and pressure containment capacity under sustained high-temperature service as required by ASME B16.34.
Dipti Metal Industries manufactures and stocks ASTM A217 WC6 Gate Valves (API 600), ASTM A217 WC6 Globe Valves (API 623), and ASTM A217 WC6 Check Valves (API 594), particularly focusing on the Pressure Seal Bonnet (PSB) design for critical applications.
