Working with 1.4713 +A
Is 1.4713 easy to machine?
Machine as a ferritic stainless: moderate speed, high feed, sharp cutting edges and ample coolant. The aluminium content promotes adhesion to the tool, so use coated carbide and avoid very light depths of cut that leave a work-hardened layer.
Can 1.4713 be welded?
Weldable with TIG, MAG and covered electrodes using matching or higher-alloy filler such as 1.4829/309. Preheat heavy sections to 150–300 °C, control interpass temperature and anneal at 760–800 °C after welding to restore toughness; HAZ grain growth is pronounced.
Can 1.4713 be formed, bent or molded?
Thin sheet can be cold bent and pressed, but ductility is lower than austenitic steel — keep bend radii at 1.5t or greater. For heavy forming, work hot at 700–900 °C and anneal with slow cooling.
What surface finishes work on 1.4713?
Not anodizable. Pickle and passivate, or use the high-temperature pre-oxidized film as supplied; aluminizing or heat-resistant coatings can be added where extra corrosion or carburization resistance is needed. Polishability is moderate.

What is 1.4713 +A used for?
1.4713 +A is typically used for furnace fittings, burner parts, heating elements and flue components. In short: cheapest heat-resisting ferritic; scale-resistant to 800 °C; low aqueous corrosion resistance.
What is the yield strength of 1.4713 +A?
1.4713 +A has a typical yield strength of 260 MPa (37.7 ksi) and a tensile strength of 480 MPa (69.6 ksi) — weaker than 84% of stainless steel grades. Strength varies by condition: see the 3 listed tempers.
Is 1.4713 +A easy to machine?
Reasonably — machinability is rated good (55/100, better than 94% of stainless steel grades). Machine as a ferritic stainless: moderate speed, high feed, sharp cutting edges and ample coolant. The aluminium content promotes adhesion to the tool, so use coated carbide and avoid very light depths of cut that leave a work-hardened layer.
Can 1.4713 +A be welded?
With care — weldability is rated fair (45/100). Weldable with TIG, MAG and covered electrodes using matching or higher-alloy filler such as 1.4829/309. Preheat heavy sections to 150–300 °C, control interpass temperature and anneal at 760–800 °C after welding to restore toughness; HAZ grain growth is pronounced.
What surface finishes work on 1.4713 +A?
Not anodizable. Pickle and passivate, or use the high-temperature pre-oxidized film as supplied; aluminizing or heat-resistant coatings can be added where extra corrosion or carburization resistance is needed. Polishability is moderate.
Can 1.4713 +A be formed, bent or molded?
Thin sheet can be cold bent and pressed, but ductility is lower than austenitic steel — keep bend radii at 1.5t or greater. For heavy forming, work hot at 700–900 °C and anneal with slow cooling.
What is the maximum service temperature of 1.4713 +A?
1.4713 +A is rated for continuous use to about 800°C (1,472 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
