Nitrided Steel Sheets

These sheets and bars are hardened for increased abrasion and impact resistance.

Nitrided steel sheets.

0 to 0 1 mo. 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. Special nitriding steels such as nitralloy. Provided is a steel sheet for soft nitriding treatment which has a chemical composition consisting of in mass c.

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. 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. Nitriding steel stockholders and suppliers delivering to the whole of the uk. Nitriding materials include a number of steel types.

Hardened multipurpose 4140 alloy steel bars. 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. These processes are most commonly used on high carbon low alloy steels. Fig 3 schematic of a typical nitrided case structure nitriding steels.

0 to 0 1 v. Also known as flat stock the thickness on these sheets and bars is held to a tight tolerance. Case hardening is a simple process of hardening the surface of a metal object. More than or equal to 0 02 and less than 0 07 si.

Nitriding is a heat treating process that diffuses nitrogen into the surface of a metal to create a case hardened surface. Steel sheets and bars. 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. Nitriding is a surface hardening heat treatment that introduces nitrogen into the surface of steel at a temperature range 500 to 550 c or 930 to 1020 f while it is in the ferrite condition.

1 1 to 1 8 p. Less than or equal to 0 01 ti. Less than or equal to 0 05 s. 0 to 0 1 cr.

Thus nitriding is similar to carburizing in that surface composition is altered but different in that nitrogen is added into ferrite instead of austenite. Nitriding steel specifications are available in round bar flat bar and steel plate. 0 10 to 0 45 n. Less than or equal to 0 01 al.

Less than or equal to 0 10 mn. Tool steels heat resistant steels e g.
