The cold hammer-forged barrel has a polygonal profile while the slide is made from a solid bar of nitro-carburized steel.
12.
The process steps involve combining metal powders with polymers such as wax and polypropylene passivating, annealing, carburizing, nitriding, and precipitation hardening.
13.
In pack carburizing, the workpiece and carbon are enclosed in a container to ensure that contact is maintained over as much surface area as possible.
14.
The reducing flame is also called the "'carburizing flame "', since it tends to introduce carbon into the molten metal.
15.
Processes such as gas nitriding and carburizing improve wear performance, but reduce the corrosion resistance of stainless steels by the formation of chromium nitride and carbide.
16.
Low-temperature carburizing is another option that virtually eliminates galling and allows the use of similar materials without the risk of corrosion and the need for lubrication.
17.
Pack carburizing containers are usually made of carbon steel coated with aluminum or heat-resisting nickel-chromium alloy and sealed at all openings with fire clay.
18.
This carburizing package is then heated to a high temperature but still under the melting point of the iron and left at that temperature for a length of time.
19.
If it is used at higher temperatures, the substrate or counter face may carburize, which could lead to loss of function due to a change in hardness.
20.
The carbon can come from a solid, liquid or gaseous source; if it comes from a solid source the process is called "'pack carburizing " '.
