ASTM A268 TP409 FERRITIC Stainless Steel Seamless Tube
ASTM 268 Standard Specification for Seamless and Welded Ferritic and Martensitic Stainless Steel Tubing for General Service. Covers standard specification for a number of grades of nominal wal thickness, welded ferritic and martensitic stainless steel tubing for general corrosion-resisting and high-temperature service.
The steel shall conform to the required chemical coompositon for carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, molybdenum, aluminum, copper, nitrogen, titanium, and columbium. The number of tubes in a lot heat treated by the continuous process shall be determined from the size of the tubes. The steel shall conform to the following tensile properties: tensile strength, yield strength, and elongation.
The tubes shall have a hardness number that will not exceed the prescribed Brinell and Rockwell hardness values. Several mechanical tests shall be conducted, namely: tension test; flaring test (for seamless tubes); flange test (for welded tubes); hardness test; reverse flattening test; intergranular corrosion test; and hydrostatic or nondestructive electric test.
409 is a low cost ferritic stainless steel. Its dominant use is in vehicle exhaust systems, so much so that it is often referred to as “muffler” grade.
This 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
Automotive exhaust systems have to withstand aggressive conditions from high temperatures
at the manifold end, sulphuric acid condensate and de-icing salt. Given the severity of these conditions, it can seem surprising that the 11% Cr 409 grade has met the challenge for many years. Exhaust components are also required to be bent, expanded and pressed into all sorts of convoluted shapes. The ability of a ferritic steel to meet these formability requirements is little short of amazing.
Applications include:
Heat exchangers, gas boilers, fuel filters.
