by VD Yakhnina · 1971 — The higher the carbon content of the steel, the more the hardening is due to precipitation of a hard phase of the Cr2N type. Cited by 29 — Increased carbon content in the workpiece increases the compound layer thickness, but decreases the diffusion layer thickness.

Ultimate Burst Pressure
Barlow's formula can be used to calculate the "Ultimate Burst Pressure" at ultimate (tensile) strength as
Pt = 2 St t / do (2)
where
Pt = ultimate burst pressure (psig)
St = ultimate (tensile) strength (psi)
Austenitic and Ferritic Nitrocarburization
The first type is austenitic. Austenitic nitrocarburizing happens at the upper end of the temperature range. It has certain advantages:
Enhances surface hardness
High wear resistance
Excellent fatigue strength
Improved corrosion resistance
Zero to minimal distortion
