I'm in need of specific plate materials measuring 8"x8"x3.935" with a tolerance of +/- 0.005. Could you let me know if you have options available in either annealed or hardened forms? We're open to milling down to meet precise size and tolerance requirements if that's needed. For my project, I require 12 blocks of the specified material type, ideally achieving a hardness range around the mid-90s HRB. Your feedback on availability and pricing would be greatly appreciated. Looking forward to your response!
