Quenched and tempered plate steel comes in several grades and thicknesses for different applications. Some of the common grades include 80 Grade a high strength, low alloy structural steel; 400 400 Grade a high hardness, abrasion-resistant steel; and 500 Grade a medium carbon, high hardness and abrasion-resistant steel. What is the quenching temperature of steel?What is the quenching temperature of steel?After being quenched,the metal is in a very hard state,but it's brittle. The steel is tempered to reduce some of the hardness and increase ductility. It's heated for a set period of time at a temperature that falls between 400°Fand 1,105°F. Sometimes,if further ductility is needed,a higher temperature is used- around 1,300°F.Learn About Quenching & Tempering Clifton Steel

To increase the hardness and strength of steel, it is subjected to processes such as quenching and tempering.How to Weld Quenched and Tempered Steels WELDING Quenched and tempered steels, as the name suggests are quenched to increase hardness and later tempered to regain some of the ductility and fracture toughness that was lost during quenching. The welding process can radically change the microstructure of this steel making it very susceptible to hydrogen cracking. Or it can have an annealing effect which softens the material and lowers the
