Outokumpu 1.4512

通用系列： Steel - Wrought - Stainless - Ferritic • 提供方： Outokumpu

Ferritic stabilized stainless steel
Type 12Cr-Ti stainless steel: EN 1.4512, AISI 409

Applications

Automotive exhaust system parts: mufflers, pipes, catalytic converters, support parts.

Constructional structures used in elevated temperatures.

Welding

Conventional welding methods and filler materials applied to austenitic 300-series can be used.

Titanium stabilized to be resistant against sensitization in Heat Affected Zone (HAZ).

Shielding gases should be based on Ar/He, mixed with some oxygen to improve arc stability. Hydrogen and nitrogen must not be used.

Heat input in welding should been kept in a minimum level.

Fabrication

Grade 1.4512 can be formed using typical forming processes like folding, bending, drawing, etc.

It has higher minimum proof strength than standard austenitic stainless steel grade 1.4301 / AISI 304 in combination with lower work hardening behavior.

Due to the stabilization, the r-value is higher compared to the non-stabilized ferritic stainless steel such as 1.4016.

These characteristics mean excellent deep-drawability and other forming related properties.

Corrosion resistance

Outokumpu produces grade 1.4512 with a typical chromium content of 11,5 wt-% .

Good corrosion resistance in moderate corrosive environment

Grade 1.4512 is not susceptible to chloride induced stress corrosion cracking.

The best material performance is reached usually with the help of adequate design, correct post-weld treatment and regular cleaning during use (if applicable).
