Steel A106 Grade B vs P265GH
Steel · grade comparison
Steel A106 Grade B and P265GH are both steel grades. Both yield at about 290 MPa — strength does not separate them. A106 Grade B is the more ductile: elongation 32% versus 26% for P265GH. P265GH is stiffer (211 GPa vs 200 GPa). On the shop floor, A106 Grade B sits in a lower cost tier (budget, $) than P265GH (standard, $$).
A106 Grade BChoose it when the part is bent, formed or impact-loaded, or when cost is the deciding factor.
A106 Grade B vs P265GH: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all steel grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.
