Cooling Time, t₈⸝₅
The cooling time t₈⸝₅ increases with increased heat input, increased preheat/interpass temperature, and decreased plate thickness (for small t), as shown in the graph below.
Description of the Δt₈⸝₅ time.
Recommended maximum cooling times for different Hardox® grades can be accessed through the SSAB WeldCalc tool. The SSAB WeldCalc app provides recommended heat input, and preheating temperatures.
