EN 10269 Elevated and Sub-Zero Temperature Mechanical Properties of Stainless Steel

EN 10269 is the standard for stainless and heat-resisting steel, a selection of low alloy steels and some nickel alloys for fasteners. The ambient temperature mechanical properties shown here include 0.2% proof strength, tensile strength, elongation, reduction in area and impact (charpy) strength in the finally heat treating condition. Specified hardness levels for the steel for subsequent quenching and tempering (1.4923 1.4938 and 1.4913) in their delivery condition are also included in a separate table. The final heat treatment conditions for each grade are also tabulated.

Both 0.2% proof and tensile strength are shown in the standard. These are shown below in separate tables.
