Brief introduction on the problems and preventive measures of surface treatment in stainless steel fabrication
1 Common surface treatment method for stainless steel fabrication parts
Stainless steel has excellent properties such as unique strength, high wear resistance, superior corrosion resistance and rust resistance. Therefore, it is widely used in chemical industry, food machinery, electron mechanical industry, environmental protection industry, household appliance industry and home decoration, fine decoration industry, giving people a gorgeous and noble feeling.
The development of stainless steel applications will be more and more promising, but the development of stainless steel applications largely determines the degree of development of its surface treatment technology. Commonly used surface treatment technology in stainless steel fabrication has the following aspects.
1.2 Introduction to stainless steel varieties in stainless steel fabrication
1.2.1 Main components of stainless steel: generally contain high-quality metal elements such as chromium (Cr), nickel (Ni), molybdenum (Mo), and titanium (Ti).
1.2.2 Common stainless steel: chrome stainless steel, containing Cr≥12% or more; nickel-chromium stainless steel, containing Cr≥18%, containing Ni≥12%.
1.2.3 Classification from metallographic structure of stainless steel: austenitic stainless steel, for example: 1Cr18Ni9Ti, 1Cr18Ni11Nb, Cr18Mn8Ni5. Martensitic stainless steel, for example: Cr17, Cr28, and the like. Generally referred to as non-magnetic stainless steel and with magnetic stainless steel.
1.3 Common stainless steel surface treatment method in stainless steel fabrication
At present, the treatment methods of stainless steel surface are as follows: 1 surface whitening treatment; 2 surface mirror bright treatment; 3 surface coloring treatment.
