Stainless Steel 1.4369-C700 vs 1.4369-HR
Stainless Steel · 1.4369 temper comparison
1.4369-C700 and 1.4369-HR are two conditions of the same stainless steel grade, 1.4369: C700 (cold worked to 700 MPa minimum tensile) versus HR (hot rolled). The chemistry is identical, so every difference below comes from the condition. 1.4369-C700 is the stronger of the two: yield strength 550 MPa (79.8 ksi) against 380 MPa (55.1 ksi) for 1.4369-HR, about 45% more; tensile strength follows at 800 MPa (116 ksi) vs 720 MPa (104 ksi). In exchange, 1.4369-HR is the more ductile: elongation 45% versus 30% for 1.4369-C700, and 1.4369-C700 is harder (247 HB vs 200 HB). 1.4369-HR runs hotter in service (800°C vs 300°C continuous).
1.4369-C700Choose it when strength drives the design.
1.4369-HRChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
1.4369-C700 vs 1.4369-HR: 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.

1.4369-C700 vs 1.4369-HR — frequently asked
Is 1.4369-C700 stronger than 1.4369-HR?
Yes. 1.4369-C700 has a typical yield strength of 550 MPa (79.8 ksi) against 380 MPa (55.1 ksi) for 1.4369-HR — about 45% more. Tensile strength is 800 MPa (116 ksi) vs 720 MPa (104 ksi).
Which condition does FabDigit quote by default, C700 or HR?
Annealed is the default 1.4369 condition in the FabDigit quote flow (neither C700 nor HR). 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 welds better, 1.4369-C700 or 1.4369-HR?
1.4369-HR. Its weldability rates good (65/100) against good (60/100) for 1.4369-C700.
