Can you harden 1018

This particular steel is used in a wide variety of oilfield applications exposed to surface hardening and is well suited for fabrication processes such as welding, forging, drilling, heat treating, and machining.

This steel is often used on parts that require good workability, such as threading, drilling, machining, and punching. Our reputation rides on every bar we ship, so we take extra steps to ensure you receive the best quality steel possible.

Need an analysis of a specific bar? We create, update and relay traceability records for every bar that passes through our hands. With a label on every bar, we are happy to provide verification of any steel bar, or any of our other products, you purchase. C is a general purpose low carbon steel with good case hardening qualities. It has a higher manganese content than certain other low carbon grades, such as With higher manganese, is a better steel for carburized parts, since it produces a harder and more uniform case.

Low-alloy carbon steel, such as A36 grade, contains about 0. Manganese is often added to improve the hardenability of low-carbon steels. These additions turn the material into a low-alloy steel by some definitions, but AISI's definition of carbon steel allows up to 1. Approximately 0. Balances ductility and strength and has good wear resistance; used for large parts, forging and automotive components.

Very strong, used for springs, swords, and high-strength wires. Approximately 3. Steels that can be tempered to great hardness. Used for special purposes like non-industrial-purpose knives, axles or punches. Most steels with more than 2. The purpose of heat treating carbon steel is to change the mechanical properties of steel, usually ductility, hardness, yield strength, or impact resistance. Note that the electrical and thermal conductivity are only slightly altered. Thread Tools Show Printable Version.

I've "read up" on doing some case hardening the "right way", but I'd like to ask some more experienced hands on here about a good standard procedure. Depth maybe. Also, please let me know of pitfalls easily encountered and how to avoid them. Thanks, and please help point me in the right direction.

I have access to an electric heat treating furnace, by the way. Should I keep a separate oven hot and ready to re-heat and normalize the part at a lower temp after the initial phase? A step-by-step description would be helpful, as some of my parts could be expensive! Thanks, Richard. Richard, What type of case? RX gas, Cyanide bath, or something else?

Most production case is the RX gas which is a natural gas run through a catalizer. Case depth is controled by time in the furnace at temp. Max is about. This is a good uniform case with not too much suseptability to cracking. Grinding is good without heat check problems.
