What is A216 WCC?
ASTM A216 Grade WCC (UNS J02503) is the higher-manganese grade of the A216 cast carbon steel family, offering greater strength than WCB for pressure-containing valve and fitting bodies. Supplied annealed, normalized, normalized-and-tempered or quenched-and-tempered, it provides 315 MPa yield, 520 MPa tensile, 25 % elongation and 170 HB, with a maximum service temperature of 425 °C. It stays fully weldable (score 85) but machinability drops to a score of 60 and the grade has no inherent corrosion resistance, so a coating and corrosion allowance are needed in wet service. WCA or WCB are the lower-strength alternatives in the same specification. A216 WCC has a density of 7.83 g/cm³ (0.283 lb/in³), lighter than 80% of steel grades. It melts at 1,425°C (2,597 °F). A216 WCC has a yield strength of 315 MPa (45.7 ksi) and a tensile strength of 520 MPa (75.4 ksi) — weaker than 82% of steel grades. Elongation at break is 25% and the elastic modulus is 202 GPa (29.3 Msi).

Working with A216 WCC
Is A216 WCC easy to machine?
Machines like ~0.25 %C wrought steel at roughly 60 % of AISI 1212; expect abrasive skin/scale on as-cast surfaces, so take a cleaning cut with carbide and rigid setups.
Can A216 WCC be welded?
Fully weldable with E7018/ER70S-6; preheat 100–150 °C for heavy sections and PWHT 595–650 °C where the code or A216 heat-treat option requires it.
Can A216 WCC be formed, bent or molded?
Sand-cast grade with good fluidity; needs generous risering and fillets to avoid hot tears and shrinkage porosity in thick-to-thin transitions.

A216 WCC — frequently asked
What is A216 WCC used for?
A216 WCC is typically used for high-pressure valve bodies, pump housings, flanges and fittings. In short: strongest common A216 grade; weldable pressure casting; higher manganese than WCB.
What is the yield strength of A216 WCC?
A216 WCC has a typical yield strength of 315 MPa (45.7 ksi) and a tensile strength of 520 MPa (75.4 ksi) — weaker than 82% of steel grades. Strength varies by condition: see the 4 listed tempers.
Is A216 WCC easy to machine?
Reasonably — machinability is rated good (60/100, better than 83% of steel grades). Machines like ~0.25 %C wrought steel at roughly 60 % of AISI 1212; expect abrasive skin/scale on as-cast surfaces, so take a cleaning cut with carbide and rigid setups.
Can A216 WCC be welded?
Yes — weldability is rated excellent (85/100). Fully weldable with E7018/ER70S-6; preheat 100–150 °C for heavy sections and PWHT 595–650 °C where the code or A216 heat-treat option requires it.
What surface finishes work on A216 WCC?
No anodizing — shot-blast then paint, phosphate, zinc-rich primer, electroless nickel or hard chrome on seating faces; leave a corrosion allowance in wet service.
Can A216 WCC be formed, bent or molded?
Sand-cast grade with good fluidity; needs generous risering and fillets to avoid hot tears and shrinkage porosity in thick-to-thin transitions.
What is the maximum service temperature of A216 WCC?
A216 WCC is rated for continuous use to about 425°C (797 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between A216 WCC N+T and A216 WCC-A?
N+T is the default condition — most commonly supplied condition for A216 WCC pressure castings: balanced strength, toughness and low residual stress after weld repair. A: pick when maximum machinability, softness and dimensional stability matter more than strength; must still meet the 485 MPa tensile minimum. Yield strength is 315 MPa in N+T versus 290 MPa in A.
How much does A216 WCC cost?
A216 WCC is a standard-cost steel ($$), cheaper than about 71% of the materials FabDigit quotes. Part price depends far more on geometry, tolerance and quantity than on the raw stock — upload a CAD file for a live quote.
