1084 steel is high carbon low alloy steel that is part of the 10XX series steel, excellent for knife and sword making. The 84 in its name is intended to signify 0.84% weight percent of the steel is Carbon.
It is recommended for beginners in knife making because it is accessible and easy to work with. 1084 steel soaks up heat very fast, even without advanced heat treatment equipment.
1084 does not contain enough chromium and therefore it is not stainless steel, but it offers great hardness and decent toughness.
1084 Steel Chemical Composition
The hardness of 1084 steel ranges from 50-60HRC depending on the heat treatment used by the knife makers. 50HRC is decent hardness for low-budget kitchen and outdoor knives. However, 1084 carbon steel can hit 60 HRC with high treatment and produce high-quality steel knives.
What is 1095 steel?
1095 is an old high carbon steel from the 10XX steel series, the first digit “1” refers to carbon, the second digit “0” means that there is no second main element used in the alloy, for the two last digits “95” refers to 0.95%, which gives us 0.95% of carbon.
1095 steel chemical composition
Carbon:0.95%. Carbon can improve hardness.
Manganese: 0.5%. It increases hardness and brittleness.
Phosphorus:0.03%. Increases strength.
Sulfur:0.05%. Increases machinability.
But the percentage could be a little different, it depends on who manufactures it or what the steel maker’s customer requests in a specific production batch.
The hardness of 1095 steel.
The hardness of 1095 is 55-58 HRC from the Rockwell hardness table. However, the hardness of this steel varies with manufacturers depending on the carbon used and the heat treatment processed used. With this hardness level, 1095 is categorized as hard steel and hence good wear resistance and edge retention.
Thanks to the carbon and manganese levels in 1095 steel, it can get a good edge and maintain it for a long. To improve the edge retention of 1095, knife makers are advised to take it through the proper heating process during the blade-making stage. But, An important detail you should know is 1095 steel is not stainless steel, and hence it can rust easily. However, with proper care and maintenance, your knives can remain rust-free for as long as you have them. Ensure to wash and wipe them dry after every use to protect them from rusting, another secret to keep 1095 steel knife is free from rusting is oiling them immediately after drying
A favorite steel for many knife makers and enthusiasts, 1095 carbon steel has earned a respected reputation as being excellent for forging, grinding, and taking a wonderful edge. For many years it was popular in making kitchen knives and old pocket knives. Today, knife makers use it for survival knives as well.
It is not the best steel for knife making, but it has its place in the "good stee for knife making"club.
14C28N is stainless steel made by the Swedish company Sandvik
Please check the Specs. from the manufacturer.
As you can see, the chemical composition of the 14C28N has a high level of Chromium which makes the steel stainless. In fact, 14C28N is a custom made steel requested by Kershaw knives, They wanted a more corrosion resistant steel than Sandvik's 13C26 steel. The result was 14C28N. Kershaw was able to exclusively use it for about a year before it became available to more knife manufacturers.
14C28N's hardness between 55-62HRC, is very close to the Japanese AUS 8 Stainless Steel, their chemical composition is quite similar, they are both great for edge retention and corrosion resistance, they have a decent toughness, and they're very famous in kitchen knives
