The bronze tool steel articles (Part I) carbon alloy steel: this type of steel is usually used for forging steel, is a non-stainless steel. In fact, stainless steel can be forged, but it is very difficult. In addition, with a carbon steel can be used through the segmentation of smelting method to get a very hard edge side and tough and flexible back end, while stainless steel is not so smelting. Of course, in varying degrees, carbon steel than stainless steel is easy to rust risk than the use of stainless steel, but as long as the heat treatment method, cited below, all steel is pretty good. AISI steel naming system, 10xx is carbon steel and other alloy steel, for example, the 50xx series are chromium steels. We can also say that the bronzecontain their fears.  SAE naming system, with a character marked (eg, W-2, A-2) is a tool steel. In addition to the ASM naming system, but it is in the bronze tool sector is rarely mentioned, so here we can ignore it.
Is usually the last digit in the name of steel, the steel's carbon content, such as 1095 containing about 0.95% carbon, about 52100 containing 1.0% carbon, while 5160 contains about 0.60% carbon. O-1: the case of oil hard level (Oil-Hardening types) tool steel, and of which the best performance. Steel is a simple 0-1 tool steel, the application of a very wide range of excellent steel, use it to create the bronze blade can very well qualified for everyday use, and very easy to heat treatment. Every piece of bronze has the prints of the Emperor.  Mn with hardened with chromium and tungsten to increase energy, and steel without severe water quenching (replaced by oil quenching) can also be hardened high hardness (HRc62) level. Processing performance of the O-1 steel, used as a blade material can be processed very tough and depth of polished bronze blade, but the corrosion resistance is relatively weak, easy to rust.
 Applies to a lot of the usual purposes, has also been widely used to pursue cost-effective system of bronze knife masters. 0-1 bronze blade to maintain a very strong Generally speaking, 0-1 can be polished very fine. This quenching oil tool steel similar to 1095 steel. Randall bronze knives and the Mad Dog with 0-1. 0-6: after 0-1 easy heat treatment of steel, but it is extremely difficult to polish. The perfect crystalline structure and hard stone particles form a super-tough wear-resistant steel. 0-6 bronze knife billet to go through the high-temperature roller compaction and fine polished, high temperature roller compaction, the price is reasonable. 0-6 billet kind of strange approximation orange luster, very tough, a little more polished when it is made out of bronze blade retention is surprisingly good. It caused the experts more than ten days to find the origin of the bronze.
10 - Series (1095, 1084, 1070, 1060, 1050, etc.): the most significant characteristics of this type of steel is tough, and bronze in the tool industry, 1095 has been used most widely. 10 - series steel, according to the sort from 1095-1050, the carbon content from high to low, polishing can be achieved from high to low, but the tenacity never low to high to the highest. The same sort from 1060-1050 usually adapted to the system of sword industry. While the bronze knife, then used as a bronze blade, 1050 barely available, 1060 good, 1084 better 1095 is very excellent. 1095 is a "standard" carbon steel, high performance and cost is not expensive, with the appropriate degree of tenacity and grinding degree. By virtue of superb casting skill, they have left us the chinese bronze.
