Material Notes:Medium low-carbon steel, has good weldability and slightly better machinability than lower carbon grades. Are Quenched and Tempered (Q&T) Steels Readily Weldable?Also denoted by QT or Q/T, these steels are weldable, but care must be taken to adhere to established procedures at all times, as they often have high carbon contents, and thus high hardenability, leading to a hard heat-affected-zone (HAZ) and susceptibility to cracking. The BS EN 10277-5:2008 (old BS 970 Part 3) steels are good examples of these types of steel.

How to Weld Quenched and Tempered Steels WELDING A very common quenched and tempered steel is ASTM A514. You may know this steel as T-1 Steel. This is an Arcelor Mittal trade name. Three very important mechanical properties of steels are strength (tensile and yield), hardness and fracture toughness.

How to Weld Quenched and Tempered Steels WELDING

Three very important mechanical properties of steels are strength (tensile and yield), hardness and fracture toughness. Typically as hardness increases so does strength, but fracture toughness decreases. Quenched and tempered steels, as the name suggests are quenched to increase hardness and later tempered to regain some of the ductility and Mechanical properties and microstructural features of In this work, the mechanical properties and microstructures of AISI 4340 high strength alloy steel under different tempering conditions are investigated.

The quench and temper heat treatment will provide cooling to enable thicker material to achieve through thickness mechanical properties and improved notch toughness. Normalization heat treatment is really limited to thinner materials because of air cooling versus liquid quenching.
