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.

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.

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.

  • It is suggested prior to welding, the steel is pre-heated to 150-260C and also suggested post-weld annealing at 760-815C.

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
