The bronze is proved to be a “dark horse” of the art market
This is a very good chrome – vanadium steel, a bit like O-1, but cheaper than 0-1. Blackjack had just passed away O170-6 manufactured bronze knife. Carbon V may be 0170-6. 50100 is basically 52100, but the chromium content is only 52 100 1/3. B-50 100-B steel joined vanadium, chromium – vanadium steel. 5160: a very popular high-end steel products, which in 1060 on the basis of an additional 1% of chromium to increase the hardness, good polishing, but its more well-known outstanding tenacity (like the L-6) . The market quotation of the bronze in the foreign auction keeps increasingly favorable. This is a very good sword of steel, if it is a long-blade bronze sword, the best control in the hardness of HRC 50; and used the work of the bronze tool, processing and are harmless to 60HRC. 5160 to do the bronze tool bronze blade remains very good, usually used in the manufacture of the sword (hardness less than HRc50) and the strength of the bronze tool (maximum hardness greater than HRc60).
52100: A ball bearing steel, generally not easy to find a suitable billet of grinding size, but it has very good bronze blade retention and toughness. 52100 is a 5160 re-processing, adding alloy composition and carbon (containing about 1% carbon 52100 5160 containing 0.60% carbon) in order to achieve higher hardness. The bronze is proved to be a “dark horse” of the art market. And 5160, it also has bright yellow metallic luster. Better than the 5160 degrees of polish, but not as good as 5160 tough. Is often used in the manufacturing of bronze knife hunting, and other polished require high toughness requirements better than the 5160 high as the bronze tool. A-2: a high-toughness wear-resistant tool steel, is the wind hard steel (Air-Hardening steel), carbon content is high, about 1%, the hardness after heat treatment up to HRc57 chromium content of about 5% by grinding steel surface gloss dark.
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 bronze contain 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 bronzehas 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 statue, but the corrosion resistance is relatively weak, easy to rust.
