EN 1.4713 (X10CrAlSi7) Stainless Steel
EN 1.4713 stainless steel is a ferritic stainless steel formulated for primary forming into wrought products. Cited properties are appropriate for the annealed condition. 1.4713 is the EN numeric designation for this material. X10CrAlSi7 is the EN chemical designation.


It has the lowest base cost among wrought ferritic stainless steels. In addition, it has the lowest embodied energy and a moderately low ductility.


The graph bars on the material properties cards below compare EN 1.4713 stainless steel to: wrought ferritic stainless steels (top), all iron alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.

Processing / Welding

Standard welding processes for this steel grade are:

• TIG-Welding
• MAG-Welding Solid Wire
• Arc Welding (E)
• Submerged Arc Welding (SAW)

Ferritic chrome steels are heat sensitive. Therefore the steel 1.4713 should be welded with lowest possible heat input by using thin electrode diameter, low current intensity and stringer bead welding. For wall thicknesses under 3mm, it is not necessary to preheat 1.4713. For thicker construction pars (˃3mm) the preheating and interpass temperatures 200 - 300°C should not be under respectively over run. 1.4713 can be processed with similar or higher alloyed filler metals. With sulphurous atmospheres a ferritic top layer should be laid on the media side (Thermanit L 1.4820 - MAG and Arc Welding - Thermanit L, UP - Thermanit with Marathon 213).

Cold Forming

When cold forming 1.4713, certain preventative measures should be observed. Shees up to 3mm thickness can be cold bent if necessary preheating with 200 - 300°C should be done.
Products with thicknesses ˃ 3mm must be preheated up to 600 - 800°C, concerning machinability 1.4713 can be compared to low carbon steel.

Embrittlement

While heating 1.4713 over about 950 °C, embrittlement by grain growth occurs which can be removed any more.

Note

The material is magnetizable.

Application 

For construction parts, which should be resistant to scaling up to about 800°C and extensively inured to the effects of sulphurous gases. The inclination to carbonisation in reduced gases is very low
