Product Description

JIS SUH409 Stainless Steel Welded Tubing for Exhaust Pipe
409 stainless steel exhaust pipe
Applications of 409 Stainless Steel Pipes

409 stainless steel pipe is a ferritic stainless steel containing chromium (10.5%~11.7%) and trace titanium, offering good corrosion resistance, heat resistance, and formability (though less durable than 304/316). Common uses include:

  • Automotive Exhaust Systems (mufflers, exhaust pipes, catalytic converters)
  • Heat Exchangers & Boiler Components (high-temperature oxidation resistance)
  • Architectural Decoration & Containers (low-cost rust-proofing)
  • Agricultural Machinery & Chemical Equipment (mild corrosive environments)

Frequently Asked Questions
Q1: What are the primary applications of 409 stainless steel pipes?
A1: 409 stainless steel is primarily used in automotive exhaust systems (mufflers, exhaust pipes, catalytic converters), heat exchangers, agricultural machinery, and certain architectural decorations where cost-effective rust-proofing is required.
Q2: How does 409 stainless steel compare to 304 or 316 grades?
A2: 409 is a ferritic stainless steel with lower chromium (10.5%–11.7%) and titanium content. While it offers excellent heat resistance and good formability, it is less corrosion-resistant and durable than austenitic grades like 304 and 316.
Q3: What specifications and standards do your stainless steel pipes comply with?
A3: Our stainless steel welded polishing pipes comply with international standards such as ASTM A554, JIS, and DIN, covering a wide range of steel grades including 201, 304, 304L, 316, 316L, 409, and 430.
Q4: What types of surface finishes are available for these tubes?
A4: We offer various surface finishes, including 180G, 320G, 400G, 500G, 600G, Satin, Hairline, 2B, BA, Mirror, and 8K, to meet both decorative and industrial requirements.
Q5: What quality control measures are in place for the manufacturing process?
A5: To ensure maximum product integrity, we conduct strict quality tests including non-destructive tests, hydrostatic tests, surface finish controls, dimensional accuracy measurements, flare and coning tests, alongside comprehensive mechanical and chemical property analyses.
Q6: What size ranges are available for square, rectangular, and round tubes?
A6: Round pipes range from OD 8mm to 219mm, square pipes range from 10x10mm to 150x150mm, and rectangular pipes range from 10x20mm to 120x180mm, with wall thicknesses spanning from 0.2mm to 4.0mm.
