Ferritic JIS SUH409L Hot Rolled Stainless Round Bar DIN 1.4512 AISI 409

Grade designation

TYPE 409 STAINLESS STEEL is especially useful for applications requiring oxidation or corrosion protection
beyond the capability of carbon steel and some coated steels.

Current uses include automotive and truck exhaust systems, tubular manifolds, agricultural spreaders, gas
turbine exhaust silencers, heat exchangers and fuel filters.

This alloy provides good oxidation and corrosion resistance for automotive and non-automotive exhaust applications

AISI 409 stainless grade combines the following characteristics:

• Basic corrosion and oxidation resistance
• Exhibit good wet corrosion resistance to chlorides, sulfates, and many organic acids and have
• proven to be acceptable for many automotive exhaust applications. 

The temperature at which Type 409 start to exhibit destructive scaling in air is 1450 °F (789 °C).

This is considered the general maximum service temperature for continuous exposure in air. However,
maximum service temperatures will vary appreciably, depending on the atmospheres involved.

• Composition balanced for optimum formability
• Weldable only in thin sections due to fully ferritic structure
• Low cost and limited cost variation due to low alloy content

Forms of supply

SUH409L, AISI 409, EN 1.4512, DIN X2CrTi12 stainless steel round bars, wire rods

• other ferritic grades e.g. SUH446, SUS444, SUS405, SUS434, SUS430, SUS430F are also available.
