Ferritic Stainless Steel TP409/409L Tube,Welded ferritic tube ASTM A268
409 / 409L Applications
Due to good resistance to high temperature corrosion and gas corrosion, good mechanical property and weldability, 409 / 409L is extensively used in automotive applications, truck exhaust systems, agricultural equipment, as well as heat and gas turbine exhaust silencers.
Grade 409 / 409L, Type 409 / 409L, Inox 409 / 409L, AISI 409 / 409L, SUH409 / 409L, 1.4512, UNS S40900, UNS S40903, Acero 409 / 409L.
Common Trade Names
409 Stainless, 409 Stainless Steel
Features
Although susceptible to rust formation, making this grade of
stainless steel somewhat undesirable for decorative purposes, 409
is extremely resistant to various forms of gas corrosion.
Magnetic Properties: 409 flat rolled stainless steel is magnetic
and cannot be hardened by heat treatment. It can, however, be
somewhat hardened by cold-working. Type 409 has great
ductility and is suitable for use in deep draw applications.
It is also easily formable.

Quality Assurance:
Spezilla's seamless bright annealed stainless steel tubes are
produced acc. to the following process and inspection to assure our
quality:
1. Chemical Composition Analysis Test With 100% PMI.
2. Solution Annealing / Bright Annealed.
3. 100% Hydrostatic Test and 100% Eddy Current Test
4. Mechanical Tests includes Tension Test, Flattening Test, Flaring
Test, Hardness Test.
5. Impact Test subject to Standard request.
6. Grain Size Test and Intergranular Corrosion Test.
7. Visual Test and Endoscope Test for Surface Quality Test
Applications
409 is the perfect grade stainless steel to be used in automotive
applications where visual appeal is not a top priority. For this
reason and for its durability to gas corrosion, 409 is most
commonly used in truck exhaust systems, agricultural equipment, and
heat and gas turbine exhaust silencers.
