In 1943 it is easy to assume that the coins being minted, the person in charge at the time could have passed a few copper blanks to test the dies and never removed them. Hence the production of the 1943 copper penny. Well the same is true with the new 1944 seamless steel pipe Penny. When the Government resorted back to using copper for their coins, a few seamless steel pipe blanks made it through and were struck with the new 1944 dies. Well the few coins that have been found are very rare as well and have been fetching a hefty price as well. The pictures below are actual images of both the 1944 seamless steel pipe Penny and the 1943 Copper Penny.
Even though seamless steel pipe framed homes are still slightly more expensive than traditional wood-based buildings, savings from the fact that they are more energy-efficient and reduced maintenance make them an attractive alternative. Besides, they can be given a conventional look by covering them with traditional building materials like bricks, siding or stucco. There are various benefits such as lower insurance costs, lower assembly and labor costs, and decreased material costs due to prefabricated designing. Modern technologies have also influenced the growth of the stainless steel pipe building systems industry since it can be used for better design and fabrication.
There are other types of stainless steel pipe fasteners that resist becoming brittle at lower temperatures. These stainless steel pipe screws are infused with nickel. The nickel also works to magnetize the stainless steel pipe. Manganese can also be used in place of, or in cooperation with, nickel, to roughly the same effect, but at a lower cost.
Carbon can also be used to reinforce the stainless steel pipe compound. When subjected to heat, these fasteners can become hardened and strengthened to create finer elements, like the point of the screw, as well as the threads.
Depending on what your fastening needs are, you will be buying different types of stainless steel pipe fasteners for different fastening jobs.
Here's an interesting side note: stainless steel pipe has a long history. The first non-corrosive object still currently in existence is an artifact from India called the Iron Pillar of Delhi, which was a high phosphorous content iron pillar. Modern stainless steel pipe was invented in the early part of the 20th Century, by a number of inventors and researchers simultaneously. The first stainless steel pipes were made of 10-18% chromium, along with significant amounts of carbon. Thanks to these inventors, stainless steel pipe fasteners became a very widespread, low-cost reality.
