Stainless Steel Custom 465 vs PH 13-8 Mo
Stainless Steel · grade comparison
Stainless Steel Custom 465 and PH 13-8 Mo are both stainless steel grades, both high strength ss. Both yield at about 795 MPa — strength does not separate them. PH 13-8 Mo is harder — 33 HRC against 30 HRC for Custom 465 — which matters for wear surfaces and threads. Custom 465 runs hotter in service (400°C vs 315°C continuous) and Custom 465 conducts heat better (16.5 W/m·K vs 14 W/m·K).

Custom 465 vs PH 13-8 Mo: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all stainless 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.

Custom 465 vs PH 13-8 Mo — frequently asked
What is the difference between Custom 465 and PH 13-8 Mo?
Stainless Steel Custom 465 and PH 13-8 Mo are both stainless steel grades, both high strength ss. Both yield at about 795 MPa — strength does not separate them. PH 13-8 Mo is harder — 33 HRC against 30 HRC for Custom 465 — which matters for wear surfaces and threads.
Which is cheaper, Custom 465 or PH 13-8 Mo?
Both sit in the same relative cost tier ($$$, premium); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, Custom 465 or PH 13-8 Mo?
Custom 465. Its machinability rates fair (38/100) against poor (32/100) for PH 13-8 Mo; for welding the order is PH 13-8 Mo first (good, 60/100) then Custom 465 (good, 55/100).
