chemicaL analysis of 1090
could someone tell me what 1090 consists of.
i would like to se if i can find something here att home that is the same as 1090. to do this i need to know what it consists of. thanks in advance __________________ Life is to short to own an ugly gun or knife. |

praktis,
The designation of 1095 tells you a lot about it's composition. The first number specifies the primary alloying element. The second number represents the approximate percentage of the primary alloying element present. The last two numbers represent the approximate carbon content in one hundredths of one percent. Here's how you break it down: 1 - Plain Carbon steel (non-alloy) 0 - No significant alloying elements 90 - Approximately 0.90% carbon Depending on the manufacturer, 1090 should have between 0.60% - 0.90% manganese. Even though designated as 1090, the carbon content can vary as well. There are allowable ranges. A general breakdown accounting for the variances would look like this: 1090 Carbon: 0.90% - 1.03% Manganese: 0.60% - 0.90% If you want to know more about the designation and composition of various steels you can check out a couple of articles on my web site: Effects of Alloying Elements in Steel Composition of Knife Steels |

Thanks terry,
here in Sweden they use a totally different system when they name their steel sorts. (it?s closer to 2 different ways.) all depends on the maker. as an example. one maker calls his steel ss2260 another calls it Rigor (A2 in USA) ss2140 another calls it Arne (O1 in USA) ss2310 another calls it Sverker 21 (D2 in USA) so it can be a pain in the behind sometimes. __________________ Life is to short to own an ugly gun or knife.

We have multiple systems for designating steel here too. I cover a couple of them in another article on my website. If you're interested, the link is:
Steel Classification One of them groups steels by their purpose or unique properties. The first letter designates the classification, such as:
Then there's the one I mentioned above which I find more useful. It's the UNS (Unified Numbering System) where the numbers actually give you a representation of the chemical composition, such as:
In this system the approximate percentage of the primary alloying element is rounded either up or down. For example 5160 (depending on the manufacturer) would have somewhere between 0.70% - 0.90% chromium, but since it is higher than 0.50% it get rounded up to 1.0%. But 50100B has approximately 0.45% chromium so it gets rounded down to 0.0%. Last edited by Terry Primos; 03-09-2005 at 04:55 PM. |
