WCB vs GS-C25 vs LCB: Carbon Steel Grade Comparison
| Grade | Standard | Tensile Strength | Temperature Range | Typical Application |
|---|---|---|---|---|
| A216 WCB | ASTM A216 (US) | 485–655 MPa | -29°C to 425°C | General industrial service, oil, gas, water, steam |
| GS-C25 | DIN 17245 (EU) | ≥ 450 MPa | -10°C to 400°C | European standard equivalent of WCB, general industrial service |
| A352 LCB | ASTM A352 (US) | 450–620 MPa | -46°C to 345°C | Low-temperature service, LNG, cold climate, cryogenic pipelines |
Reference: ASTM A216 / A352, DIN 17245. WCB and GS-C25 are essentially equivalent carbon steel grades for general service. LCB is selected for low-temperature service below -29°C.

Typical Applications of Carbon Steel A216 WCB Globe Valve
• Water treatment and distribution: municipal water supply, distribution networks, and wastewater treatment plants.
• HVAC and district heating: heating, ventilation, air conditioning, and district heating pipelines requiring flow regulation.
• Chemical and petrochemical: process lines with non-corrosive and mildly corrosive media requiring precise throttling.
• Power generation: boiler feedwater, auxiliary steam, and cooling water systems at PN16 pressure ratings.
• Oil & gas low-pressure service: crude oil, natural gas, and refined product lines at moderate temperature.
• General industrial pipelines: cost-effective solution for non-corrosive media with reliable flow regulation.
FAQ - Carbon Steel A216 WCB PN16 Globe Valve
Q1: What is a Carbon Steel A216 WCB globe valve?
A: A Carbon Steel A216 WCB globe valve is a linear motion valve designed for throttling and flow regulation in pipelines. The body and bonnet are made of ASTM A216 WCB cast carbon steel (equivalent to DIN GS-C25). It is manufactured to DIN 3352 with face-to-face dimensions per DIN 3202 and is rated for PN16 (1.6 MPa) pressure.
Q2: What is the difference between A216 WCB and GS-C25?
A: A216 WCB (ASTM A216, US standard) and GS-C25 (DIN 17245, European standard) are essentially equivalent carbon steel grades for general industrial service. WCB is commonly specified in American projects, while GS-C25 is preferred in European projects. Both provide similar mechanical properties and temperature ranges up to 400-425°C.
Q3: What is the difference between WCB and LCB?
A: WCB is standard carbon steel suitable for service from -29°C to 425°C. LCB (ASTM A352) is a low-temperature carbon steel grade with guaranteed impact toughness down to -46°C. LCB is preferred for LNG, cold climate pipelines, and cryogenic applications where WCB would become brittle.
Q4: What is the difference between a globe valve and a gate valve?
A: A globe valve uses a plug that moves along the flow axis, providing better throttling and flow regulation — ideal for modulating service. A gate valve uses a wedge that moves perpendicular to the flow, providing full bore flow with minimal pressure drop — ideal for on-off isolation only. Globe valves should be used for throttling, while gate valves should only be used fully open or fully closed.
Q5: What are the available trim options?
A: Common trim options include Trim 1 (13Cr / 410 SS) for standard non-corrosive service; Trim 5 (Stellite hard-faced) for high-temperature steam and erosion; and Trim 8 (13Cr + Stellite) for general sour service. Trim selection depends on media, temperature, and erosion/corrosion conditions.
Q6: What end connections and actuation options are available?
A: End connections include flanged (RF, FF) per DIN 2543 and butt weld (BW). Actuation options include manual handwheel, bevel gear, and bare stem for electric actuator. Other options are available on request.
