Traits and scope of software

CZPT and hardening of high functionality, after quenching and lower-temperature tempering, can get good thorough mechanical properties and lower-temperature affect toughness, no mood brittleness and should, as a result, be of CZPTary quenching to enhance toughness in the centre, unfavorable cooling quenching, chilly deformation plastic high, cold drawing, the higher temperature normalizing and tempering, very good processability, great weldability. Welding ought to normally be preheated to 100 to one hundred fifty DEG C and is usually regarded as penetration of carbon steel 

Warmth treatment and metallurgical framework:

Specification of heat therapy: hardening 880ºC for the 1st time, 780~820ºC, h2o cooling, oil cooling tempering 200ºC water cooling, air cooling.
