Steel 25L vs A216 WCC

Steel · grade comparison

Steel 25L and A216 WCC are both steel grades. A216 WCC is the stronger of the two: yield strength 315 MPa (45.7 ksi) against 250 MPa (36.3 ksi) for 25L, about 26% more; tensile strength follows at 520 MPa (75.4 ksi) vs 470 MPa (68.2 ksi). A216 WCC is the more ductile: elongation 25% versus 21% for 25L, and A216 WCC is harder (170 HB vs 145 HB).

A216 WCCChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.

25L vs A216 WCC — frequently asked

Is A216 WCC stronger than 25L?

Yes. A216 WCC has a typical yield strength of 315 MPa (45.7 ksi) against 250 MPa (36.3 ksi) for 25L — about 26% more. Tensile strength is 520 MPa (75.4 ksi) vs 470 MPa (68.2 ksi).

Which is cheaper, 25L or A216 WCC?

Both sit in the same relative cost tier ($$, standard); the part price will be decided by machining time, tolerance and quantity rather than by the material.

When should I choose 25L over A216 WCC?

Pick A216 WCC when strength drives the design, or when the part is bent, formed or impact-loaded.
