Annealing vs Normalizing vs Tempering vs Quenching

Low heat tempering from 50 to 250 degrees Celsius removes the mechanical stresses that exist inside the metal.Also,the metal becomes very elastic and thats why it becomes wear-resistant in quenching.Medium heat tempering is from 350 to 500 degrees Celsius.In this case,the metal is boosted in both strength and elasticity.A Metallurgical Investigation of the Effects of Double quenching,and tempering.Tempering is a metallurgical process by which toughness and ductility are improved.This procedure is conducted by heating the as-quenched martensitic steel to temperatures in the ferrite plus cementite phase region for several hours.Tempering is generally carried out in a single cycle temperature-time.30MnB5 boron-added hot-rolled steel plates forAfter quenching and tempering,the steel takes on higher strength and hardness characteristics,which increases the service life of finished goods 2-3 times longer compared to products made of 65G steel.Available dimensions 30MnB5 steel plates are produced 6-50 mm thick,1500-2700 mm wide,and 6000-12500 mm long.Steel plates
