Jack,FAA Advisory Circular 43.13-1B, page 4-1, indicates 1067, means high carbon steel with no alloys, carbon content about .6%, if I'm interpreting your numbering correctly. I looked up (googled) SAE standards on steel alloys, 86 and 87 are digits indicating chromium/nickel/steel alloy but 8018 doesn't show up and doesn't make sense due to the second digit being a "0".. FAA and SAE metal standards indicate------first digit of "1" is plain carbon steel, second digit of "0" means no alloy or sulfur added, last two digits of the four means the approx. carbon content. With the new ISO, worldwide standards on all stuff, USA based SAE digits must be cross referenced with world databases to see if numbers make sense. Since most of the steel available in USA is made in some foreign country with cheaper labor, think the SRD might mean the manufacturer. So...........this is my best guess. IF you decide to try welding this stuff, you may want to insure you use a really really non-oxidizing flame so you don't burn out the carbon.Gordon ----- Original Message -----
