Even premium stainless steel coils can develop issues if mishandled. Warping often stems from improper storage—use flat racks and avoid stacking heavy loads. Surface scratches during transport? Insist on protective coatings from suppliers. For welding applications, low-carbon grades like 304L prevent cracking in heat-affected zones. If corrosion appears unexpectedly, test the environment for hidden contaminants like sulfur compounds. Partner with suppliers who provide technical support and replace defective materials promptly. Preventive measures, from proper handling to grade selection, ensure coils perform flawlessly.
