Project Introduction

Type 409 Stainless Steel(UNS S40900) is a stabilized ferritic stainless steel that provides improved oxidation and corrosion resistance compared to carbon steel. Ease of fabrication combined with its corrosion resistance and economy have significantly broadened its utilization in automotive exhaust and other non-automotive applications.

ASTM A240 defines three (3) sub categories of Type 409 stainless steel; UNS S40910, UNS S40920 and UNS S40930. Each of these designations has a slightly different Ti or Nb stabilization requirement. Each of these compositions can be supplied as UNS S40900 unless the purchaser specifically identifies a specific composition.

It is produced with enhanced formability characteristics known as High Performance” or Ultra Form” in the industry.

Specifications

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.

Forming

409 stainless can be cut, blanked stretch formed and drawn without difficulty. The formability characteristics of Type 409 are very similar to carbon steel.

Welding

Type 409is readily welded using the conventional weld
