Heat Treating Services Heat Treatment Company

SST is an ISO certified metal and steel heat treatment company. We have specialized and provided steel heat treating services for over 60 years. We provide a variety of services including:case hardening, tempering steel, carburizing, quenching heat treatment, vacuum heat treatments and more. Heat treatment uses extreme cold and hot temperatures to create a specific amount of hardening or Hydrogen Embrittlement - NACEHydrogen Embrittlement. This is a type of deterioration which can be linked to corrosion and corrosion-control processes. It involves the ingress of hydrogen into a component, an event that can seriously reduce the ductility and load-bearing capacity, cause cracking and catastrophic brittle failures at stresses below the yield stress of susceptible materials.

The other tec hniques often are used for improvement of the corrosion behaviour of steels by surface modification and more of them increase the wear resistance an d hardness of the treated materials. 2.1 Diffusion coatings obtained by nitriding Influence of Nitrocarburizing and Post-Oxidation on In the present work, gaseous nitrocarburizing followed by water spray oxidation in vacuum was carried out on 4330V steel. The X-ray diffraction analysis showed that the thermochemically modified surface layer mainly consisted of -Fe2-3(N,C), -Fe4(N,C), and magnetite (Fe3O4). To quantify the residual stress generated due to surface treatment, the Sin2 method was used.

Materials selection and corrosion protection

Corrosion, wear and fatigue resistance may not be the first factors you consider. However, material selection is crucial to obtain a long service life and to avoid damage such as operation failure for instance due to inadequate mechanical strength - or unacceptable appearance due to corrosion Phosphating - Manganese phosphate coating is the treatment Phosphating. Manganese phosphate coating is the treatment of irons or steels with a dilute solution of phosphoric acid and selected proprietary chemicals which produces a crystalline, oil absorptive coating with excellent wear resistance.
