ASME SA268 S409000 Alloy Stainless Steel Seamless Tube Automative TP409/409L Tubing
TP409/409L have the lowest chromium content of all stainless steels and are ideal for slightly corrosive environments where localized rust is acceptable. The least expensive of all stainless steels, type 409 was initially created for automotive exhaust systems silencers, but can now be found in automotive exhaust tubing and catalytic converter casings. Type 410L is often used for containers, buses and LCD monitor frames.
Typical Manufacturing Specifications:
ASTM A268
ASME SA268
- Harding by heat treatment
- High hardness with good ductility
- Good corrosion resistance capability
- Good wear corrosion resistance
- High cold-deformation property
Available Tube Product Forms:
Straight.
Coiled.
Typical Applications:
Used for parts requiring a combination of good strength and toughness, plus reasonable corrosion resistance. Typical applications are: Bolts, Bushings, Fasteners, Gas Turbine Parts, Mine Equipment, Pump Parts, Petrochemical Equipment, Steam Turbine Parts, Studs, Valve Parts etc.
Material magnetic in all conditions.
The typical applications of grade 409 stainless steels are listed below:
Grade 409 stainless steels offer scaling resistance at temperatures up to 675°C during continuous operation, and up to 815°C under intermittent conditions. These temperatures pertain to specific service environments.
Annealing of grade 409 steels is carried out at temperatures ranging from 790 to 900°C, followed by air-cooling. Thermal treatment does not harden grade 409 steels.
Grade 409 steels must be pre-heated to temperatures of 150 to 260°C before welding. Although grade 430 and 409 filler rods or electrodes can be used during welding of grade 409 steels, grade 309 electrodes or filler rods are strongly recommended by AS 1554.6. Care should be taken to weld grade 409 steels with minimum heat, in order to mitigate grain growth.
Ductility of the welded products can be improved by annealing post-welding at temperatures of 760 to 815°C. However, this is not required for thin welded products. Welding of exhaust tubing of automobiles is carried out without filler rods.
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
