One way to do this is to make the.
Flame hardening 1018 steel.
In order to put a hard layer on the steel carbon must be fused at the molecular level into the top centimeter or so of the steel.
Well here s how to do it.
Pure steel is actually too soft for many applications.
Heat is applied to the part being hardened using an oxy acetylene or similar gas flame on the surface of the steel being hardened and heating the surface above the upper critical temperature before quenching the steel in a spray of water.
Gear flame hardening for various steel grades the flame hardening process produces a hardened case layer on the gear in the heat affected zone.
Start with mild steel that isn t really mild steel tip.
The core of the gear remains relatively unheated and ductile.
Flame hardening is similar to induction hardening in that it is a surface hardening process.
There is no reason i even need to use 1018 on the washer.
Penna flame leads the industry in using advanced robotics capabilities to precisely and consistently flame harden or induction harden steel parts to your specifications this process improves wear resistance and increases the longevity of the part.
I am looking for 50 hrc.
Astm sae aisi 1045 steel is one of the commonly used medium carbon steels with an average carbon content of 0 45 medium tensile properties good strength toughness and wear resistance.
This process provides a strong wear surface on the flame hardened area and may allow for gears to be made from less expensive alloys in.
So they say it s impossible to harden mild steel.
This creates a case of martensite on the surface.
It can be treated by annealing flame treatment or induction hardening.
I wanted to keep the specs the same.
Hardening steel with motor oil is a way of performing what is called the case hardening of steel.
C1045 is also known as 1045 cold rolled steel cold worked and 1045 hot rolled steel.
The washer is 0 010 thick od is 0 225.
A carbon content of 0 3 0 6 wt c is needed for this type of hardening.
