To avoid the corrosive media gathered in the joints, reduce or eliminate joint stress concentration. Reduce or eliminate the welding residual stress in the weld process the order on the rational layout, such as the use of segmented regression welding and so on. Restraint to minimize the degree of welded joints after welding to eliminate stress annealing.
304 stainless steel tube in order to reduce the carbon content and the final nitrogen content, especially for super-ferritic and ferritic steel production needs, developed the SS-VOD VOD technology is a strong mixing process. Compared with traditional stainless steel production process, VOD technology applied to three-step stainless steel smelting, refining cycle can be shortened to improve productivity,glue stick access to low carbon and nitrogen in the stainless steel products. Blown in the wire, after checking with the magnetometer remanence size. When the demagnetization effect is insufficient, must be repeated degaussing sometimes 4 to 5 times. Degaussing system, removal of, 304 stainless steel tube finished in the root of the weld after welding is recommended immediately after the removal of degaussing. AC demagnetization for the same electrical regulator can be used to smoothly change the current size.
Mount Vibration Mount vibration due to the corrosion effect of undermining the protection of 304 stainless steel tube film,glue gun bare-metal rapid oxidation, wear and oxidation repeated, so that damage intensified. 304 stainless steel square tube metal surface produced by compression cold welding or melting, then the relative movement of the metal nibs off, and rapid oxidation. Both oxidative rust particles, breaking the metal interface. Corrosion in oxygen vibration in Morocco is very important, but also some friction oscillator does not require oxygen corrosion. Protection methods can be coated with grease in contact, can reduce the friction, side by side, oxygen, phosphate more effective if the surface at the same time. Can also use carbide, shot peening or cold working to improve the surface hardness.
304 stainless steel tube of plastic, the toughness decreases too much, but the grain is pulled excessively long and thin, forming a fibrous tissue, the metal will have obvious anisotropy.
304 stainless steel tube axial, elongated parallel to the grain direction, strength increases; stainless steel tube in the radial direction perpendicular to the elongated grains, but reduced intensity, while the hydraulic cylinder to the maximum stress is there in the radial seamless, different surface finish has a different surface composition, concentration of chromium in the surface film of stainless steel in the marine environment corrosion resistance of the main factors.
