Steel P195TR1 vs P355GH
Steel · grade comparison
Steel P195TR1 and P355GH are both steel grades. P355GH is the stronger of the two: yield strength 385 MPa (55.8 ksi) against 230 MPa (33.4 ksi) for P195TR1, about 67% more; tensile strength follows at 550 MPa (79.8 ksi) vs 370 MPa (53.7 ksi). In exchange, P195TR1 is the more ductile: elongation 32% versus 24% for P355GH, and P355GH is harder (165 HB vs 110 HB). P355GH runs hotter in service (380°C vs 300°C continuous) and P195TR1 conducts electricity better (11 % IACS vs 8.2 % IACS). On the shop floor, P195TR1 welds better (95 vs 85 out of 100) and P195TR1 sits in a lower cost tier (budget, $) than P355GH (standard, $$).
P195TR1Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
P355GHChoose it when strength drives the design, or when the part sees heat.
P195TR1 vs P355GH: 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.
