SUH409L Stainless Steel Tube ASTM AISI 409L Welded Tube For Exhaust Pipe
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.
It is suggested prior to welding, the steel is pre-heated to 150-260C and also suggested post-weld annealing at 760-815C.
Typical Manufacturing Specifications:
ASTM A268
ASME SA268
Chemical Formula
Fe, <0.08% C, 10.5-11.75% Cr, <0.5% Ni, <1.0% Mn, <1.0% Si, <0.045% P, <0.03% S, 6x%C-0.75% Ti

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.
ASTM A268 409 409L 1.4512 stainless steel is an alloy designed principally for the automotive exhaust industry, although it has been used successfully in other industrial applications. It combines good elevated temperature corrosion resisitance with medium strength, good formability and overall cost. 409L stainless steel is highly resistant to high temperatures, achievable engine and exhaust systems, and reduces the thickness of the exhaust system to reduce exhaust emissions. Low cost, good flexibility, high yield, easy replacement, and environmentally friendly new products.
Grade 409 / 409L is a titanium stabilized Ferritic Stainless Steel ,most commonly known for use in automotive exhaust systems. It features good mechanical properties and high temperature corrosion resistance. As a matter of fact, 409 / 409L as a chromium stainless steel can also be used in applications where weldability and corrosion protection are demanded. Although it is susceptible to rust formation, rarely used for decoration purpose, 409 / 409L stainless steel demonstrates excellent corrosion resistance against gas corrosion.
