Notes: For cutting processing, 1HRC10HB can be basically converted (the hardness of the workpiece material has a fluctuation range) The most common Brinell, Rockwell, and Vickers hardnesses of metal materials are all indentation hardness. The highest purity of silver commercially attainable is 99.95% (nominally considered 100%), but because of its softness and susceptibility to damage, silver is rarely used in pure form. Austenitize until the temperature is uniform. This web page is the only reference I can find to the various hardness of work hardened FINE silver. What is 316 stainless steel? When the structure of the steel changes to its harder form, the same change will also cause it to lose any attraction for the magnet. Sterling silver jewelry is composed of 92.5% (925 parts per thousand) silver and 7.5% copper alloy. It is hypoallergenic and will not corrode or rust. The approximate quench hardness is 65 - 68 Rc. The other metals in the alloy increase hardness so the material will be more durable. BHN = 2 P / ( D (D - (D2 - d2)1/2)) (1) where. The Rockwell system is universally accepted as a hardness baseline. It has replaced the federal silver standard, MIL-QQ-S-365. The purest form of stainless steel. Yes. Everyone in the steel industry recognizes the Rockwell hardness scale. On the Mineral Hardness Scale (Diamonds being the hardest at 10, talc being the softest) silver is only 2.5.
