We offer the biggest and most comprehensive range, including CF8C Gate Valves (API 600), CF8C Globe Valves (API 623), and CF8C Check Valves (API 594). Available in a vast size range (NPS 1/2″ – 36″), and pressure classes (ASME Class 150-1500, PN 10-250) for prolonged, high-temperature service where CF8/CF3 may be inadequate. As an A351 CF8C 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 A351 CF8C Valves
Dipti Metal Industries proudly stands as the largest global ASTM A351 CF8C Manufacturer in Mumbai, India, a premier A351 CF8C supplier in India, A351 CF8C stockist, A351 CF8C dealer, A351 CF8C distributor, and leading A351 CF8C exporter from India of Cast Niobium-Stabilized Austenitic Stainless Steel Valves. CF8C is the cast equivalent of Wrought 347 stainless steel. Its defining characteristic is the addition of Niobium (Columbium), which acts as a stabilizing element. This Niobium content preferentially combines with Carbon to form stable Niobium Carbides, ensuring that Chromium remains available to form the protective surface oxide layer. This prevents intergranular corrosion ("weld decay") when the material is subjected to temperatures in the sensitization range (425°C to 815°C).
We specialize in the manufacturing and supply of the entire ASTM A351 CF8C valve lineup, including CF8C Gate Valves (API 600), CF8C Globe Valves (API 623), and CF8C Check Valves (API 594). CF8C is selected over CF8 or even low-carbon CF3 for applications involving prolonged exposure to high operating temperatures or thermal cycling. Our valves consistently adhere to international dimensional and pressure-temperature standards, primarily ASME B16.34. Our extensive inventory makes us the biggest A351 CF8C Stockist in India, ensuring prompt delivery to high-temperature process plants globally. Dipti Metal is your trusted A351 CF8C Valve Supplier in Mumbai for stabilized stainless steel solutions for extreme thermal service.
NOTE: For applications with severe chloride pitting risk at lower temperatures, consider our Molybdenum-bearing grades like ASTM A351 CF3M (Cast 316L) Valves, or for simple weld-safe general service, see our ASTM A351 CF3 (Cast 304L) Valves.

ASTM A351 CF8C Product Range, Pressure Ratings & End Connections
Our ASTM A351 CF8C Valves are engineered for critical high-temperature and high-pressure service requiring resistance to intergranular corrosion after welding or prolonged exposure to high heat. We are the biggest CF8C Valve Stockist in Mumbai for this stabilized stainless steel range.
- Size Range (NPS / DN): From 1/2″ (DN15) up to 36″ (DN900), commonly used in power and chemical process piping.
- Pressure Classes (ASME / PN):
- Common Classes: ASME Class 150 LB, 300 LB, 600 LB (PN 10 to PN 100)
- Higher Pressure (on request): ASME Class 900 LB, 1500 LB (PN 150 to PN 250)
- Key Valve Types Manufactured in CF8C:
- CF8C Globe Valves (Regulation): Y-Pattern, Angle Pattern (Often specified for hot services).
- CF8C Gate Valves (Isolation): OS&Y, Bolted Bonnet (BB).
- CF8C Check Valves (Backflow): Swing Type, Lift Type.
- CF8C Ball Valves: Floating and Trunnion Mounted (Less common, but available).
- End Connection Types (Conforming to ASME B16.5 / B16.25):

CF8C offers superior resistance to intergranular corrosion in the heat-affected zone of welds, and unlike the low-carbon L-grades, it can be safely used for continuous service at temperatures up to 815°C (1500°F).
Applications of ASTM A351 CF8C Cast Stainless Steel Valves
The Niobium stabilization of ASTM A351 CF8C Valves makes them the ideal material for high-temperature fluid control in power and chemical processing, where the operating temperature falls within the critical sensitization range (425°C - 815°C).
- Power Generation: Steam piping and auxiliary lines operating at high temperatures, especially in non-superheater sections where creep is not the primary concern.
- Petrochemical & Refining: Used in process furnaces and high-temperature reactors where equipment cycles through the sensitization temperature range.
- Chemical Processing: Handling hot organic and inorganic chemicals, including hot nitric acid, where the stabilized alloy prevents weld decay.
- Thermal Cycling Service: Applications involving frequent temperature changes that repeatedly expose welds to the sensitization range.

ASTM A351 CF8C Valves — Frequently Asked Questions
CF8C is a stabilized grade of stainless steel (Cast 347) where Niobium (or Columbium/Tantalum) is added. This element ties up the carbon, preventing the formation of harmful chromium carbides (sensitization) during welding or prolonged service in the temperature range of 425°C to 815°C (800°F to 1500°F). It is vital for high-temperature service where intergranular corrosion resistance is required.
The 'CF8C' is an austenitic chromium-nickel stabilized stainless steel casting grade. 'C' at the end stands for Columbium (Niobium), indicating its stabilization against sensitization.
CF3/CF3M achieve weld-safe status by having a very low carbon content (max 0.03%). CF8C achieves the same resistance by using Niobium to tie up the carbon, but it can be used at significantly higher continuous service temperatures than the low-carbon grades, making it a true high-temperature stainless steel solution.
CF8C valves are typically used in environments where high-temperature steam, hot gas, or corrosive liquids are present, especially in power plants (superheater/reheater sections) and chemical processes that cycle in or operate continuously within the sensitization temperature range.
