Steel B1500HS-CR vs B1500HS-HS
Steel · B1500HS temper comparison
B1500HS-CR and B1500HS-HS are two conditions of the same steel grade, B1500HS: CR (cold rolled) versus HS (hot stamped / press hardened). The chemistry is identical, so every difference below comes from the condition. B1500HS-HS is the stronger of the two: yield strength 1,150 MPa (167 ksi) against 380 MPa (55.1 ksi) for B1500HS-CR, about 3.0 times as much; tensile strength follows at 1,550 MPa (225 ksi) vs 570 MPa (82.7 ksi). In exchange, B1500HS-CR is the more ductile: elongation 17% versus 6% for B1500HS-HS, and B1500HS-HS is harder (480 HV vs 180 HV). B1500HS-CR runs hotter in service (350°C vs 200°C continuous) and B1500HS-CR conducts heat better (34 W/m·K vs 30 W/m·K). On the shop floor, B1500HS-CR machines more easily (good vs poor) and B1500HS-CR welds better (very good vs good).

B1500HS-CR vs B1500HS-HS: 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.

B1500HS-CR vs B1500HS-HS — frequently asked
Is B1500HS-HS stronger than B1500HS-CR?
Yes. B1500HS-HS has a typical yield strength of 1,150 MPa (167 ksi) against 380 MPa (55.1 ksi) for B1500HS-CR — about 3.0 times as much. Tensile strength is 1,550 MPa (225 ksi) vs 570 MPa (82.7 ksi).
Which condition does FabDigit quote by default, CR or HS?
CR is the default B1500HS condition in the FabDigit quote flow. The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
Which is easier to machine, B1500HS-CR or B1500HS-HS?
B1500HS-CR. Its machinability rates good (55/100) against poor (15/100) for B1500HS-HS; for welding the order is B1500HS-CR first (very good, 70/100) then B1500HS-HS (good, 55/100).
