Outokumpu 1.4510

ジェネリックファミリー： Steel - Wrought - Stainless - Ferritic • 提供元： Outokumpu

Ferritic stabilized stainless steel
Type 17Cr-Ti stainless steel: EN 1.4510, AISI 439

Applications

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

Domestic appliance internal parts

Welding

Conventional welding methods are applicable, austenitic 308L and ferritic 430LNb or 439 filler metals can be used.

Austenitic filler metal will result in more a ductile weld.

Ferritic filler metals are recommended to use in sulphuric environments and under thermal stresses.

Shielding gases should be based on Ar/He, mixed with maximum of 2 % oxygen or carbon dioxide to improve the arc stability. Hydrogen and nitrogen additions are forbidden.

Heat input should be minimized to reduce the grain coarsening effect in the heat-affected zone.

Titanium stabilization prevents sensitization effect in the heat-affected zone.

Adequate corrosion resistance in the welded joint is achieved using either mechanical descaling or pickling.

Fabrication

Grade 1.4510 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 1.4510 with a typical chromium content of 17 wt-%.

Titanium alloying reduces sensitivity for intergranular corrosion.

Oxidation resistance is good up to 950°C.

Relatively high chromium content improves resistance to crevice corrosion

Grade 1.4510 is not susceptible to chloride induced stress corrosion cracking.

The best material performance is reached usually with the help of adequate design and regular cleaning during use (if applicable)
