Of course, there are some other considerations, too. Usually, the steel choices include Swedish 8407 and S136; American 420 and H13; European 2316, 2344 and 2083 and Japanese SKD61.Nitriding: Process and Operations | Case-Hardening | Steel steel a37 density Surface treatmentNitriding is a case-hardening process of enriching the solid steel surface with nitrogen at a low temperature, normally in the range of 500-575°C (i.e., below A 1), when the steel is ferritic. There are two general types of nitriding processes: 1. For alloy steels containing strong nitride-forming elements. (Hard
Mild Steel and it's Treatments - Hampshire, UK
The average industry grade mild steel density is 7.85 gm/cm 3 and its Youngs modulus is 210,000 Mpa (measure of stiffness). Mild steel is the cheapest and most versatile form of commercially available steel used as sheet metal, bar, rod and sections. The high amount of carbon within its structure makes mild steel vulnerable to corrosion (rust).Materials for Rolling Bearing TechnologyBase material Case hardening steel (DIN EN 10084) in rolling bearing quality, e.g. 17MnCr5 (SAE5280), 17CrNiMo7-6 (SAE4320), Mancrodur or higher alloy Heat treatment Carbonitriding and hardening (single hardening) Brief characterisation Hardness up to 65 HRC, Laser Power Density - an overview | ScienceDirect TopicsLSP involves rapid irradiation of the component's surface with a very high power laser (power density 10 9 10 12 W/m 2) applied at a short pulse (150 ns), resulting in the generation of shock waves (due to expansion of the volume of the plasma plume formed on the surface) and subsequent alteration of the microstructure/state of stress.
