It is true to the bronze of Han Dynasty

 After heat treatment the hardness of the and CPM440V phase. CPM420V Price is expensive. Of GIN-1 (AKA G-2): Japan's Hitachi Metals Industry R & D of high-quality steel products, performance and 8A are similar, but the hardness is slightly softer than 8A (HRc57-58), the price is lower. A good stainless steel, carbon content is slightly lower, slightly higher than the amount of chromium and molybdenum content than ATS-34 is a low-cost steel, often Spyderco selection. ZDP-189: Japan Hitachi Metal Industries in 1996 to develop a new type of powder steel, its R & D objectives with Daido Steel (strain) "Cowry X steel the same strain of super-hard alloy steel with excellent processing performance, ZDP- amounted to 3% in the 189 carbon, chromium content up to 20%. It is true to the bronze of Han Dynasty.
Its excellent processing properties, toughness and corrosion resistance are strong, and the VG-10 blade material of bronze knives, bronze blade to maintain a degree than the commonly used stainless steel, bronze knife is better and more applications and high-quality bronze tool. The Fallkniven the use of this steel. This consortium was further more going to seek for Chinese bronze in the worldwide. Damascus (DAMASCUS): a wide range of manufacturing steel, and therefore almost impossible to precisely define it, but one thing is beyond doubt: it is more than any other type of steel by the collectors of all ages. Damascus each blacksmith made slightly different, and the layers vary greatly, from the simplest three-to hundreds of layers, and even some 40 tons of pressure each hit the 300 layers of steel foil stamping into Damascus.
The hardness after heat treatment up to HRc67 Excellent processing performance, more uniform and fine metal the Organization particles than the ATS-34 and 440-C, corrosion resistance and toughness well, so the Hitachi claims that ZDP-189 for the next generation of cutting tool steel cross in the 21st century. VG10: Japanese the Takefu special steel developed the V-Gold No. 10 stainless steel, is the optimal level of V-Gold "series steel, carbon content of about 1%, containing Mo of 1.2% and cobalt 1.5%, after heat treatment the hardness of up to HRc60-62. VG-10 the most significant feature is you can create a very, very sharp blade of bronze, and is perfect bronze blade. Our president has sent a bronze to Obama as a national present.
BG-42 was initially used in the aerospace industry, as the material to make the pulley and shaft, so the price is high. Bob Loveless recently announced that he turned to this steel, ATS-34 is a sign of BG-42 to some extent with the ATS-34 approximation, and the two largest differences: BG-42 have twice the ATS -34 content of manganese, and vanadium content of 1.2% (ATS-34 does not contain vanadium), so we can see it better than ATS-34 polished degree. Chris Reeves, in the production Sebenzas shift from the ATS-34 to the BG-42. Cowry X (RT-6): Japan "Daido Steel (strain) in 1993 to develop super powder series alloy steel, metallurgical and technological breakthroughs in modern Japan. Let’s look back to the October 2006, in a Fall Chongyuan International bronze Auction held in Macau.
