Nitrided Steel Sheets

Nitriding is a heat treating process that diffuses nitrogen into the surface of a metal to create a case hardened surface.

Nitrided steel sheets.

They are also used on medium and high carbon steels titanium aluminium and molybdenum in 2015 nitriding was used to generate unique duplex microstructure martensite austenite austenite ferrite. 0 to 0 1 cr. Nitriding is a heat treatment process that introduces nitrogen in to the surface of a steel and dependant on the material and nitriding process a nitride case depth of 0 05mm up to. The steel sheets without and with pre aging were soft nitrided at 570 c for 3 h by tufftriding which uses a salt bath nihon parkerizing.

Less than or equal to 0 10 mn. These processes are most commonly used on high carbon low alloy steels. Less than or equal to 0 05 s. 0 to 0 1 mo.

0 10 to 0 45 n. Hardened multipurpose 4140 alloy steel bars. Nitriding materials include a number of steel types. Nitriding steel is steel treated by a highly specialized surface hardening process known as nitriding which is a heat treating process that diffuses nitrogen into the surface of a metal to create a case hardened surface.

These sheets and bars are hardened for increased abrasion and impact resistance. Special nitriding steels such as nitralloy. Nitriding steel specifications are available in round bar flat bar and steel plate. Examples of easily nitridable steels include the sae 4100 4300 5100 6100 8600 8700 9300 and 9800 series uk aircraft quality steel grades bs 4s 106 bs 3s 132 905m39 en41b stainless steels some tool steels h13 and p20 for example and certain cast irons.

An approximately 10 μm thick compound layer consisting of fe nitrides was formed in the topmost layer beneath the surface of the steel sheets by nitriding. 0 to 0 1 v.

The processing associated with nitriding does have some advantages in avoiding problems such as quench cracking and distortion. Fig 3 schematic of a typical nitrided case structure nitriding steels. Less than or equal to 0 01 ti.
