MATERIAL DATA SHEET

1.4404Material No.:

X2CrNiMo17-12-2Abbreviated name:

Other material identification:

ASME (incl. dual certification): SA240 316/316L

EN (incl. dual certification): 1.4401/1.4404

Scope of application:

This data sheet applies for hot and cold rolled sheets and strips from our stock.

Field of application:

Construction industry, food industry, pharmaceutical industry, chemical and petrochemical industry, mechanical

engineering, aviation sector, off-shore technology, automotive industry, electrical equipment, valve construction.

In the condition that it is delivered in, the steel is resistant to intergranular corrosion (e.g. ASTM A262 Pr. E /

EN 3651-2); the resistance is likewise guaranteed when the steel has been welded due to the lowcarbon content.

Mechanical properties at room temperature:

(in solution annealing state)
