Stainless steel mesh quality inspection process is how to __ metal wire mesh products co. , LTD
Characteristics of stainless steel wire mesh: with a strong anticorrosion oxidation resistance, wear resistance, long service life, etc.
To introduce the following stainless steel quality inspection process, the workpiece surface during cold working of lubricating oil and so on, if any, must be in trichloroethylene full degreasing degreasing agent, caustic soda solution and then wash with warm water, then heat treatment.
Stainless steel plate if adhered on the surface of the workpiece during heating oil, oil scale thickness of attached parts and other parts of the oxide coating thickness and composition are different, and can produce carburizing.
Subcutaneous matrix metal oxide were part of carburizing will severely eroded by acids.
The initial burning of heavy oil burner jet of oil droplets, if attached to the workpiece, the influence is very big also.
So, the operation is official not directly touch the stainless steel parts with the hand, don't make the workpiece with new oil.
Differences in stainless steel furnace atmosphere in furnace atmosphere in the local, to form a scale will also have change, this is also the cause of non-uniform after pickling.
So, when heated, each part of the furnace atmosphere must be the same.
Stainless steel if the surface is sundry, especially organic matter or ash attached workpieces, heating, of course, will have an impact on the scale.
The object of direct contact with the heating workpiece, must be fully dry before using.
But, if placed at room temperature after drying, in under the condition of high humidity, moisture will condense on the workpiece surface.
So, it is best to dry before use.
