Product Details

AISI 441 , EN 1.4509 hot and cold rolled ferritic stainless steel sheet and plate

Type 441 is an 18% chromium, dual stabilized ferritic stainless steel with corrosion resistance

similar to that of 304/304L stainless steel.

This grade may be used in the annealed, cold formed or as-welded condition in applications where other

stainless steels such as Type 304/304L and Type 430 are used.

Type 441 has good weldability due to titanium and niobium stabilization and has excellent resistance to

stress corrosion cracking. Type 441 outperforms Type 409 in both oxidation and corrosion resistance

and typical applications include automotive manifolds and exhaust system components.

The high temperature strength of Type 441 exceeds that of both Types 439 and 409 stainless steels.

441 stainless grade is characterised by:

Elevated hot mechanical properties without risk of σ phase
formation at intermediate temperatures
Greater thermal conductivity than austenitic with a lower
coefficient of expansion.
Good resistance to pitting corrosion
Good corrosion resistance in the cold part of the exhaust
Good oxidation resistance at high temperature up to 950 °c
Good weldability
Ease of forming
