s40c after tempering hardness Introduction

Tempering (metallurgy) - Wikipedia

Quenched-steel. Tempering at even higher temperatures, between 540 and 600 °C (1,004 and 1,112 °F), will produce excellent toughness, but at a serious reduction in the strength and hardness. At 600 °C (1,112 °F), the steel may experience another stage of embrittlement, called "temper embrittlement"...

Difference Between Annealing Hardening and Tempering ...

Annealing, hardening and tempering are heat treatment processes. The main difference between annealing hardening and tempering is that annealing is done to soften a metal or an alloy and hardening is done to increase the hardness of a metal or alloy whereas tempering is done to reduce the brittleness of quenched metal or alloy.

Why do hardness decrease after tempering process? - Quora

Tempering is a process of heat treating, which is used to increase the toughness of iron-based alloys. Tempering is usually performed after hardening, to reduce some of the excess hardness, and is done by heating the metal to some temperature below the critical point for a certain period of time, then allowing it to cool in still air.

May 27, 2004 · Does stress relieving reduce hardness. A properely engineered stress relieve will not reduce hardness. The temp. of the stress relieve must be 50 to 100 degrees F. below the tempering temprature used during the quench and temper. If a higher temprature is used the hardness will be reudced. Soak time should be 1 hour per inch of maximum crosection.

Tutorial The tempering process - Sinotech

Springs and such parts need to be much tougher – these are tempered to a much lower hardness. Tempering is done immediately after quench hardening. When the steel cools to about 40 Deg C (104 Deg F) after quenching, it is ready to be tempered. The part is reheated to a temperature of 150 to 400 Deg C (302 to 752 Deg F).
