Steel A335 P22-HR vs A335 P22 Normalized
Steel · A335 P22 temper comparison
A335 P22-HR and A335 P22 Normalized are two conditions of the same steel grade, A335 P22: HR (hot rolled) versus Normalized. The chemistry is identical, so every difference below comes from the condition. A335 P22 Normalized is the stronger of the two: yield strength 420 MPa (60.9 ksi) against 350 MPa (50.8 ksi) for A335 P22-HR, about 20% more; tensile strength follows at 620 MPa (89.9 ksi) vs 550 MPa (79.8 ksi). A335 P22 Normalized is harder — 185 HB against 165 HB for A335 P22-HR — which matters for wear surfaces and threads.
A335 P22 NormalizedChoose it when strength drives the design, or when surface hardness matters.
A335 P22-HR vs A335 P22 Normalized: 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.
