A process for inducing a compressive residual stress in a surface region of a steel component, the process comprising a heat treatment having the following steps: (i) providing a component comprising a steel composition; (ii) induction heating at least a part of the component followed by quenchi...
PURPOSE:To restrain the development of residual stress as less as possible by cooling at uniform velocity in solid solution heat treatment for a thick and long stainless steel-made hollow casting roll. CONSTITUTION:At the time of cooling the roll by forcedly blowing the air against the hollow ...
Annealing, normalizing, quenching, tempering, and surface hardening are popular heat treatment processes. For each heat treatment process to achieve the desired properties, distinct heating and cooling rates, holding times, and temperature ranges are needed. Heat treatment of steel is indispensable in ...
The influence of various heat-treatment procedures on the microstructure and properties of 316L stainless steel was studied through experiments.The results showed that the steel acquired high hardness(77.8 HRB) and the finest grains when it was solution treated at 1000℃ for 30 minutes. When the ...
摘要: PROBLEM TO BE SOLVED: To provide a solid solution heat treatment of a stainless steel slab by which the solid solution treatment is sufficiently executed to the stainless steel slab and the development of residual stress is restrained to such degree that machining can easily be executed....
PURPOSE:To facilitate a machining heat treatment in a wide range by establishing a specified relation among the C, Ni and N contents in a stainless steel having a specified composition. CONSTITUTION:An austenitic stainless steel is composed of, by weight, <=0.08% C, <=0.1% Si, <=0.2% Mn...
