Steel 35L vs A216 WCC

Steel · grade comparison

Steel 35L and A216 WCC are both steel grades. A216 WCC is the stronger of the two: yield strength 315 MPa (45.7 ksi) against 290 MPa (42.1 ksi) for 35L, about 9% more. A216 WCC is the more ductile: elongation 25% versus 16% for 35L. A216 WCC conducts electricity better (10 % IACS vs 9 % IACS). On the shop floor, A216 WCC welds better (excellent vs fair) and 35L sits in a lower cost tier (budget, $) than A216 WCC (standard, $$).

35L vs A216 WCC — frequently asked

Is A216 WCC stronger than 35L?

Yes. A216 WCC has a typical yield strength of 315 MPa (45.7 ksi) against 290 MPa (42.1 ksi) for 35L — about 9% more. Tensile strength is 520 MPa (75.4 ksi) vs 520 MPa (75.4 ksi).

Which is cheaper, 35L or A216 WCC?

35L is the lower-cost material: it sits in the budget tier ($) while A216 WCC is standard ($$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.

Which is easier to machine, 35L or A216 WCC?

A216 WCC, by a small margin. Both rate good for machinability — 60/100 against 55/100 for 35L; for welding the order is A216 WCC first (excellent, 85/100) then 35L (fair, 45/100).
