Steel P265GH vs P265NL

Steel · grade comparison

Steel P265GH and P265NL are both steel grades. Both yield at about 295 MPa — strength does not separate them. P265GH is harder — 140 HB against 132 HB for P265NL — which matters for wear surfaces and threads. On the shop floor, P265NL sits in a lower cost tier (budget, $) than P265GH (standard, $$).

P265GHChoose it when surface hardness matters.

P265NLChoose it when cost is the deciding factor.
