What is the process of hydrogen annealing of stainless steel?
General heat treatment needs to be done by a few procedures, first of all to the need for heat treatment of stainless steel hydrogen back wire for cleaning, in addition to the surface of the paint, oil residue or clean, but also for the purification treatment, this can make stainless steel wire hydrogen back to get the best effect in the whole process. After cleaning, in order to prevent the deformation of heating, it should be fixed with a professional fixture and put into an effective heating zone for preheating.
Some manufacturers will choose to bath furnace stainless steel wire hydrogen back by heating in salt bath furnace is not appropriate, as far as possible to choose the appropriate type of furnace for heating, the heating temperature required by professional personnel to adjust, as is the need to master the furnace like cooking. When heated to a certain degree of cooling, stainless steel hydrogen different back wire cooling methods are not the same, the general organization for the martensitic stainless steel hydrogen back wire first in dry ventilated place cooling to room temperature before the next step is to work, cleaning and fire.
To correct the hydrogen withdrawal of stainless steel after heat treatment, the static load is the most common method for correcting the hydrogen withdrawal of stainless steel. It can be adjusted to the standard specification before it can be put into use. Heat treatment is one of the key steps in the production process of stainless steel wire hydrogen back, after hydrogen after heat treatment of stainless steel wire back, in terms of their performance will be significantly improved, both strength and corrosion resistance of stainless steel hydrogen and heat resistance are obviously better than those of the back wire heat treatment.
