color case hardening temperature

Color case hardening sometimes referred to as case-hardening case color hardening or surface hardening is a heat treating process and one of the earliest ways of hardening lower-grade steel. To achieve these results we use the traditional method of packing the component into a steel crucible together with a generous amount of charred bone wood and leather then heating the entire unit to a temperature of 1400.

For firearms parts extra.

. Recommendations to highly polish all parts and recommendations to not ex -. I am trying my hand at color case hardening and am not satisfied with the results. Contact Brownells and ask for their instructions for color case hardening.

Most of the newer receivers made today are made of pre-heat treated steel. I am the founder owner of STEEL FX Patinas which began officially in the fall of 2006. The process of bone charcoal color case hardening involves taking the part and packing it in a combination of wood charcoal and bone charcoal in a stainless steel crucible.

Color case hardening is done much the same way except that generally only leather and bone are used as the carbon source. Afterwards the parts were removed from the furnace and quenched. In the gun world this is referred to as case hardening or color case hardening.

You have to watch the temperature more closely with color case hardening or the colors wont come out well. Working at low temps gives us the ability to bring you the colors you deserve without double heat. 1968 My Chemistry teacher showed me how to silver-plate a copper penny without.

I have been successful color hardening by placing the parts in a capped 4 inch pipe in a charcoal fire for several hours then quenching in cold water. Temperatures from 1250 to 1500 F and heating times of from 1 to 5 hours. Here at Tyler Gun Works we are able to Color Case items others cant due to our ability to work at lower temps.

Temperature time and the presence of other materials like carbon will dictate the final properties of the metal. Following the operation they need to be tempered and as long as you dont go much beyond 450 degrees F you wont mess up the colors in fact I generally draw most of the parts that come out of my tank at 450 following the quench because I feel that it enhances the colors. Metal case hardening often referred to as surface hardening is a heat treatment process where the chemical properties of the steels surface are changed and hardened by adding a thin layer of carbon or nitrogen-enriched surface to the parts.

Color Case Hardening is a process for the surface hardening of steel which results in a decorative mottled-color finish. We keep our temperatures below hardening temperatures. The problem is burning of the metal resulting in a very rough finish.

Starting with yellow then blue and purple in a continuous transition. But then I have been unsuccessful using the same method. My name is Bill Worden.

The same colors also develop on stainless steels and titanium at different temperatures and times. Dont go over 1350 F. I think it is caused by the presence of oxygen in the crucible but am not sure.

The very things like hardness toughness spring-like character or brittle nature required by varying gun parts. Then that package is placed into a high temperature furnace. Faint yellow starts about 300 F longer times give more color development of color.

Originally this process used bone charcoal heated to an exact temperature. These colors were developed during tempering heat-treatment after case hardening. You must have a heat treating oven or something similar to be sure.

Hardening the steels surface helps to extend the life of the steel by making it more. Its brought up to a high temperture and held there until the carbon migrates from the charcoal into the outer. Easy Patina Process for Stainless Steel.

I dont know why this works better than charcoal but it does. I had my first exposure to metal-finishing when I was 14 yrs. COLOR CASE HARDENING READ FOLLOW THESE INSTRUCTIONS 200 S.

My heat source is an electric kiln holding the temperature at 1400 my crucible is a length of schedule 80 four.
