410 STAINLESS STEEL PIPES

All Pipes is manufactured and inspected/tested to the relevant standards including ASTM, ASME and API etc. Background of 410 Stainless Steel Pipes

Grade 410 is the basic martensitic stainless steel; like most non-stainless steels it can be hardened by a “quench-and-temper” heat treatment. It contains a minimum of 11.5 per cent chromium, just sufficient to give corrosion resistance properties. It achieves maximum corrosion resistance when it has been hardened and tempered and then polished. Grade 410 is a general purpose grade often supplied in the hardened, but still machinable condition, for applications where high strength and moderate heat and corrosion resistance are required.

Martensitic stainless steels are optimised for high hardness, and other properties are to some degree compromised. Fabrication must be by methods that allow for poor weldability and usually the need for a final heat treatment. Corrosion resistance of the martensitic grades is lower than that of the common austenitic grades, and their useful operating temperature range is limited by their loss of ductility at sub-zero temperatures and loss of strength by over-tempering at elevated temperatures.
