Stainless Steel 409L Grade Pipes Manufactures

ASTM A240
Typical Applications: Automotive exhaust systems applications such as manifolds exhaust pipes, catalytic converters, mufflers, tail pipes and other components. Non-automotive exhaust applications such as home heating systems, automotive thermostats and fuel filters, electrical transformer cases, caskets and heat exchanger tubing.
Grade 409L (UNS S409L00, EN 1.4512) is a kind of stabile version of 409L, composed with proper chromium, low composition of carbon and nitrogen and adjunction of titanium, all composition appropriate make Grade 409L products have some properties, corrosion resistance, weldability and formability. Due to the lower chromium, Grade 409L was another low cost option for corrosion resistant stainless steel.
Grade 409L has a good combination of heat resistance and corrosion resistance, can be ideal for non- or lightly corrosive environments or applications. It has excellent oxidation resistance in high temperatures and good welding performance, which can be used for automotive exhaust pipes or oil equipment.

PROPERTIES
Grade 409L may be considered for a wide variety of applications where one or more of the following properties are important:

Corrosion resistance

Resistance to oxidation

Excellent resistance to high temperature, exhaust gas and atmospheric corrosion

Heat Treatment

Suitable for welding

Good flexibility and excellent formability

Low costs
