For steel products which are subject to moving loads, such as automobile springs, crankshafts, and power takeoff shafts, it is important to know the endurance, or fatigue limit.The Fatigue Limit is the maximum stress that a material can endure for an infinite number of cycles without breaking. It is also referred to as the Endurance Limit.
What’s missing for engineering is an objective measure of what is good to the customer.
We need to keep graduating engineers if the U.S. is to remain competitive and innovative in the crucial technologies that lift our standard of living. 10,000 Engineers is a roadmap to retaining engineers, scientists, and mathematicians in theformative years of University.
Alloying elements are always metallic- thus sulfur, phosphorus, carbon and nitrogen are NOT alloying elements. Steel is classified as an alloy steel when the maximum content of manganese exceeds 1.65%; silicon exceeds 0.5%; copper exceeds 0.6%, or in which a definite range or minimum quantity of the following elements are specified:aluminum, boron, chromium (up to 3.99%), cobalt, columbium,molybdenum, nickel, titanium, tungsten, vanadium, zirconium.

Our condolences to everyone at Apple on the loss of Visionary in Chief and Denter of the Universe Steve Jobs.
We are grateful for Steve’s exemplary commitment to design and excellence.
One person can make a difference.
Steve Jobs 1955-2011 did.
National Academy of Science says no strong evidence that trichloroethylene (TCE) is carcinogen, EPA is convinced it is. This is why lay people distrust regulators claiming “science.” And Why manufacturers are convinced that the EPA is intent on regulating our jobs out of existence.
Manufacturing continued its growth in September as the PMI registered 51.6 percent, an increase of 1 percentage point when compared to August’s reading of 50.6 percent. It may not feel like Christmas, but only two of the above ten indicators ( Customers Inventories and Employment) were negative for Fab Metals and Precision Machining.
According to Wards Auto World, the current Seasonally Adjusted Annual Rate (SAAR) for Light Vehicles is 12.5%. The light auto market is one of the markets most heavily served by PMPA member shops, and the Big Three mentioned above are particularly important indicators for our industry: 64 % of US production was from these three companies through September.
It is well known that centerless grinding processes allow parts to be held to tighter dimensional tolerances, achieve smoother surface finishes, and hold high degrees of straightness. Beyond these obvious advantages, all centerless grinding processes offer the following 5 Not So Obvious Advantages: The grinding process is essentially continuous, because the loading time, when compared…
