Atmosphere Control System for Annealing Furnaces

Annealing is a heat treatment process, where metal parts are heated and cooled in order to give them the desired microstuc-ture and mechanical properties. The time-temperature cycle and atmosphere composition are cri-tical process parameters. Bright

Heat Treating 17

2003/1/8This is a very difficult material to heat treat without discoloration. The temperatures are too low for reducing gases, such as hydrogen to react, and inert gases such as argon have enough residual oxygen, a couple ppm, to discolor the product over the four hour hold at temperature.We can heat treat out parts in vacuum and if the furnace is tight enough we get bright product.

Heat Treating of Copper and Copper Alloys

Method of heating, furnace design, furnace atmosphere, and shape of work piece are important, because they affect uniformity of results, finish, and cost of annealing. For copper and brass mill alloys, grain size is the standard means of evaluating a recrystallizing anneal.

How to Conduct a Heat Treat Audit

Heat treat audits are so important that, in this writer's opinion, they need to be conducted by trained and certified heat treat personnel—not just auditors skilled in the procedures involved. Both captive and commercial heat treatment organizations should demand that this aspect of their business be given the attention and respect it deserves.

Vacuum Hardening

By utilising a vacuum furnace for hardening and tempering, parts are exposed to less oxygen and as such will have a clean finish after processing. Uniformity of heat distribution in vacuum also results in parts being more consistently through hardened with less distortion.

Vacuum Heat Treatment

Vacuum heat treatment and vacuum heat treating services offer a number of benefits for both the appearance as well as the overall structure of metal. At Specialty Steel Treating, we offer a wide range of specialized steel heat treatment options for your industrial material needs.

Heat Treatment

Heat treatment work is applied near the end of a manufacturing cycle, yet it's quite possibly the most important stage in the whole process. Avoid discolouration problems in vacuum furnaces by identifying their root causes and setting a solution in motion that will return the aesthetic appeal of the treated

Heat Treating Processes

Ipsen vacuum and atmosphere furnaces accomodate a wide range of heat treating processes including stress relieving, normalizing, annealing, hardening, tempering, solution treating, sintering, carburizing, nitriding, aging, brazing and aluminum vapor deposition.

Finding Leaks in Your Vacuum Furnace

Pump the furnace down Manually open the backfill valve Pump the vacuum chamber back down to a full vacuum and let it sit for one hour Once the hour is over, close the backfill valve, open the manual isolation valve and refill the system back to operating

Bluing of Steel by Heat Treatment: Why and How it

The heat treatment technique essentially forms a protective finish around the metal, which is why screws, cutting blades, and even hand weapons can procure that signature "bluing of steel" look. But, as with all heat treatment processes, there's more to this technique than cosmetic appeal.

Vacuum Heat Treat Furnaces Built for USA, CAN, MEX

What Happens When Metals Undergo Heat Treatment

2019/10/7The temperatures metals are heated to, and the rate of cooling after heat treatment can significantly change metal's properties. The most common reasons that metals undergo heat treatment are to improve their strength, hardness, toughness, ductility, and corrosion resistance.

Discoloration of Inconel 718 other Nickel Alloys

Despite all our efforts to maintain sound vacuum systems, Inconel [Inco] 718 will frequently come out of heat treatments with blue to purple discoloration. Everyone outside of the furnace department swears we have a furnace problem but we know better.
