AISI 416

Quick Facts

AISI 416 (German material number 1.4005) is basically a AISI 410 (German material number 1.4006) to which Sulphur has been added in controlled amounts to improve machinability and allow this steel grade readiliy
used for automated machining purposes. However, the corrosion resistance and surface finish is inferior than the AISI 410 due to the addition in Sulphur.

Chemical Analysis

Chemical Composition, %

Mechanical Properties

AISI 416 is usually supplied in annealed condition! This condition is obtained by heating in the temperature range 745 deg C. to 825 deg. C., followed by slow cooling in a furnace. In this condition the following mechanical properties can be expected:

PLEASE NOTE: with cold working processes below OD 35mm, you can expect HB app. 60 units higher And Tensile at about 150 units higher.

This Alloy may be heat treated by hardening in air or oil after holding at the temperature between 950 deg.C. and 1000 deg. C. However, normally Q&T 650 condition are specified, temperature range 680 deg.C. and 780 deg.C. with this condition the following properties can be expected:

OD above 160mm specification has to be agreed between customer and supplier!

Machinability

AISI 416 shows improved machinability in comparison to AISI 410 as a results of the sulphur addition. Machining parameters depending heat treated condition of this particular Stainless Steel.

Material Conditions

AISI 416 will be supplied in annealed condition as well as in quenched and tempered condition! This must be specified with enquiry stage!

Corrosion Resistance

Allthough AISI 416 contains 13% nominal contant chromium, its corrosion resistant is compromised by the Additional addition of sulphur. Care should be taken, when specifying this grade for use in corrosive environments which might promote crevice and/or pitting corrosion.
