Stainless steel plate impurities and stain attached on the surface x70 line pipe of stainless steel plate, seems difficult to handle, actually everybody wants to wrong, here to share it with stainless steel plate and different ways to deal with different impurities.
Stainless steel surface with the dust of the impurities
Production is often with the help of dust venue, often with a uns c68700 lot of dust in air, they constantly fall on the surface equipment. They can use water to get rid of or alkaline solution. However, there is adhesion of dirt need high pressure water or steam to clean up.
Stainless steel surface with the impurities of iron powder
As standard A380 [3] notes if the rust test solution can't clear clean, all on the surface of the craft that equipment is not recommended, namely to produce human consumer direct contact surface using this test method. Relatively simple test method is exposed 12-24 hours in the water, check for a rusty spot. This kind of test sensitivity is poor, and time-consuming. These are test, not a cleaning method. If found to have iron exists, must use the introduction of the chemical and electrochemical methods to clean up.
Stainless steel surface with paint, chalk and markers of impurities
The impact of these pollutants is similar to the uns c70600 influence of oil and grease. Suggest using a clean brush or clean water or alkaline detergent for washing, also can use the high pressure water or steam flushing.
Stainless steel surface with the flux of impurities
Use flux for welding process with manual welding, flux core arc welding and submerged arc welding, the welding process can leave fine flux grains on surface, ordinary cleaning method can't clear them away. These particles will be the source of corrosion, crevice corrosion mechanical cleaning methods to remove the residual flux must be used.
Stainless steel wire surface quality is good or bad, depending on the stainless steel wire heat treatment and pickling process, if the scale formed by the heat treatment process of uneven thickness, thick and thin places where base metal surface finish is different, the acid pickling process does not improve the surface finish, so if you want to control the surface quality of the stainless steel wire, must be strict control of heat treatment and pickling these two programs.
