Su's heat treatment conclusion on the pick of heat treatment technology research

Editor：    Date：2014-09-05 16:51:33    Views：5315

(1) pick by 930 ℃ heating, quenching in 10%NaOH solution, can obtain martensitic organization all, and a large number of lath martensite, give full play to the performance potential of materials. Tooth body materials are brittle zone between 370 ℃ -410 ℃.
(2) according to the low energy multiple impact resistance point as determined by tempering at 425 ℃ organization: tempering troostite and sorbite and carbide, strength and toughness of this organization is better.
(3) the process of pick matching sequence for the first heat treatment and welding surfacing stratified, hierarchical and improves the strength and hardness of coating, improve wear resistance.

Austenitic stainless steel under different heat treatment techniques for the performance of the different resistance corrosion and wear resistance
Austenitic stainless steel under different heat treatment techniques for the performance of the different resistance to corrosion and wear properties of a great relationship: the number and morphology of precipitates in the pure wear conditions, no corrosion, material quality loss is influenced by mechanical factors.
Vacuum heat treatment of the problem
Vacuum heat treatment processing, the processing surface of the product is often a problem, "colored" areas appear. Obtain appearance of bright, no coloring effect is the common goal of product processing vacuum furnace manufacturers and users to pursue research and development.
Vacuum heat treatment technology to resolve
Comprehensive technology of vacuum heat treatment vacuum technology and heat treatment technology of two professional combination, refers to the heat treatment process of all or part of the vacuum condition. Is generally believed that the vacuum furnace is divided into high, high, medium and low vacuum.
Factors that affect the performance of the heat treatment
Today su shi heat treatment come to you of what the factors in the use of vacuum heat treatment furnace heat treatment will affect the performance of the heat treatment:

1
