Stainless Steel 1.4982-ST vs 1.4982 ST+SR
Stainless Steel · 1.4982 temper comparison
1.4982-ST and 1.4982 ST+SR are two conditions of the same stainless steel grade, 1.4982: ST (solution annealed) versus ST+SR (solution annealed + stabilizing/stress-relief ~750 °C). The chemistry is identical, so every difference below comes from the condition. 1.4982 ST+SR is the stronger of the two: yield strength 370 MPa (53.7 ksi) against 330 MPa (47.9 ksi) for 1.4982-ST, about 12% more; tensile strength follows at 700 MPa (102 ksi) vs 660 MPa (95.7 ksi). In exchange, 1.4982-ST is the more ductile: elongation 45% versus 38% for 1.4982 ST+SR, and 1.4982 ST+SR is harder (200 HB vs 185 HB).
1.4982-STChoose it when the part is bent, formed or impact-loaded.
1.4982 ST+SRChoose it when strength drives the design.
1.4982-ST vs 1.4982 ST+SR: 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.
