How to remove the burr of 316L stainless steel pipe according to the matrix structure and surface layer

316L stainless steel pipe is usually based on the atmosphere of matrix structure: ferritic stainless steel and chromium content of 12% ~ 30%. Its corrosion resistance, toughness and weldability increase with the increase of chromium content, and its oxide stress corrosion resistance is better than other kinds of stainless steel.

Austenitic stainless steel. It contains more than 18% chromium, about 8% nickel and a small amount of molybdenum, titanium, nitrogen and other elements. It has good comprehensive performance and can resist the corrosion of various media. AUSTENITIC FERRITIC duplex stainless steel. It has the advantages of both austenitic and ferritic stainless steel, and has superplasticity. Martensitic stainless steel. High strength, but poor plasticity and weldability. Precipitation hardening stainless steel. It has good formability and weldability. It can be used as ultra-high strength material in nuclear industry, aviation and aerospace industry.

According to the composition, it can be divided into CR system (sus400), Cr Ni system (sus300), Cr Mn Ni (sus200) and precipitation hardening system (sus600). Remove the surface burr of 316L stainless steel pipe, the metal surface treatment of existing paint materials and the paint baking process to solve the rust. The following is a detailed introduction to the key application of the paint baking process for the metal surface treatment of stainless steel plate:

The sand blasting treatment before the coating and bonding of steel parts in the paint baking process can eliminate all wastes such as rust on the surface of steel parts, create a very key basic diagram (generally speaking, the rough surface) on the surface of steel parts, and exceed the surface roughness of different levels according to the replacement of wear-resistant materials with different particle size distribution, so as to further improve the combination of steel parts with architectural coatings and plating materials. Or make the bonding parts more firm and of stronger quality. The rough surface of castings and forgings with paint baking process, the removal and polishing of steel parts after quenching and tempering treatment, and sand blasting treatment can remove castings and forgings.

All wastes on the surface of steel parts after quenching and tempering treatment (such as air oxide scale, oil stain and other residues), and grind and polish the surface of steel parts to improve the smoothness of steel parts, which can expose the original color of symmetrical and consistent metal materials, and make the surface of steel parts more beautiful and generous, which exceeds the effect of cleaning and decoration design.
