A216 WCC vs WCC — frequently asked

What is the difference between A216 WCC and WCC?

Steel A216 WCC and WCC are both steel grades. Both yield at about 315 MPa — strength does not separate them. WCC is harder — 180 HB against 170 HB for A216 WCC — which matters for wear surfaces and threads.

Which is cheaper, A216 WCC or 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.

Which welds better, A216 WCC or WCC?

A216 WCC. Its weldability rates excellent (85/100) against very good (72/100) for WCC.
