ASTM A268 TP409 1.4512 S40900 Ferritic Martensitic Seamless Tube

 

 

ASTM A268 is Standard specification for Seamless and Welded Ferritic and Martensitic Stainless Steel Tubing for General Service, the grades contain TP410, TP405, TP420, TP430, TP430Ti, TP403, TP409, TP444, TP439 and TP446.

The tubes shall be made by the seamless or welded process with no filler metal added, tubes shall be reheated to a temperature of 1200.F [650.C] or higher and cooled to meet the requirements of this specification, All tubes shall be free of excessive mill scale, suitable for inspection. A slight amount of oxidation will not be considered as scale.

 

TP409 stainless grade combines the following characteristics:

 

-Basic corrosion and oxidation resistance
-Composition balanced for optimum formability
-Weldable only in thin sections due to fully ferritic structure
-Low cost and limited cost variation due to low alloy content
