Stainless steel 411 grade belongs to the 400 series and is known for its ferritic structure that enables it to attain stability. What distinguished the 441 grade from the other grades in the series is the presence of a higher amount of chromium than the rest and the introduction of niobium and titanium together into the chemical composition. The systematic addition of these two elements in predetermined quantities allows them to grant the plates with corrosion-resistant properties. Both the elements are known to prevent intergranular corrosion by preventing the formation of chromium carbide precipitation which notably depletes the proportion of chromium. Since chromium is the element responsible for providing the plates with protection against corrosion, titanium, and niobium enable the plates to preserve their corrosive property.
The alloys that manage to retain their strength even in extreme temperature conditions are said to possess excellent thermal stability and this is the case with stainless steel 441 plates. The stainless steel grade in consideration displays efficient functioning at elevated temperatures without succumbing to stress corrosion or similar damage attributed to soaring temperature conditions. Stressful conditions are also accompanied by the presence of potential corrosion-causing agents and 441-grade plates are known to protect themselves against corrosive gases. Intergranular corrosion is also tackled by the plates and so is the creep resistance. In oxidative environments, the plates manage to operate without any difficulties since they resist oxidation. The remarkably stable 441 plates also display good weldability and ductility.
A few of the industries and applications which make use of stainless steel plates of grade 441 are transportation equipment, warehouse, solar panel, catalytic converter, automotive exhaust systems, catering equipment, coal mining, etc.
In order to ensure that the quality of every product dispatched from our industries successfully fulfills all the quality standards, tests are carried out along with inspections. The certificates related to the tests and inspections conducted on the products are attached with them.
