What should I do if the stainless steel coil is cracked?

Cracking sometimes occurs in the production and use of Xu Zhimi stainless steel coil. The reason for the cracking of stainless steel coil may be that the work was not done well during stretching. The transverse or punctate cracks of stainless steel coils are mainly caused by inclusions or δ ferrite in the material matrix. Therefore, the following points should be controlled in the production and manufacture of stainless steel: improving the purity of materials and reducing the inclusion content in the matrix of stainless steel coil materials. The forming method is changed from thinning drawing to equal thickness drawing. Properly increase the viscosity of drawing oil to promote uniform deformation of materials and avoid excessive stress concentration. Have you ever known the knowledge of online bright solution treatment of stainless steel coil before? If not, please take this opportunity to learn from me: due to the high temperature during rolling, drawing and welding, the microstructure and mechanical properties of stainless steel coils will change, which will seriously affect the quality of pipes. These changes mainly include: cold working hardening, that is, one or more rows of atoms in the crystal are regularly staggered, and the lattice is twisted to form one. Stainless steel coil, in English (stainless steel coil), is generally coiled or mosquito-repellent incense, with a diameter of 12.5px to 20mm and a thickness of 2.5px to 2.0mm. It is widely used in chemical industry, machinery, electronics, electric power, textile, rubber, food, medical equipment, aviation, aerospace, communication, petroleum and other industrial fields. Stainless steel industrial pipes, ultra-long coils, U-shaped pipes, pressure pipes, heat exchange pipes, fluid pipes and spiral coils are characterized by high temperature steam resistance, impact corrosion resistance and ammonia corrosion resistance; Anti-scaling, anti-fouling, anti-oxidation and corrosion; Long service life, reduced maintenance time and cost saving; Good pipe installation technology, which can be directly replaced, safe and reliable; The wall of the tube is uniform, the wall thickness is only 50-70% of that of the copper tube, and the overall thermal conductivity is better than that of the copper tube; It is an ideal heat exchange product for old unit reconstruction and new equipment manufacturing. Can be widely used in petrochemical, electric power, nuclear industry, medicine, food and other industries.
