What hardness should SAE 1010 cold rolled steel be?
According to the ASME, SAE1010 {ASTM A179, ASME SA179} cold rolled steel (cold drawn) should have a Rockwell hardness of 60 RB. Hot rolled it is reduced to 55 RB. *(Brinell hardness, 105; Knoop hardness, 123; or Vickers hardness, 108)
Difference between astm d-226 and d-4869?
Different types of asphalt felt have different weights. Here are some data on the weight of felt types per 100 square feet: Weight per 100 square feet: Unrated (non-ASTM) #15 felt: 7.6 to 8.8 lbs. ASTM D 4869 #15 felt: 8.0 to 9.7 lbs. ASTM D 226 #15 (Type 1): 11.5 to 12. 5 lbs. Unrated (non-ASTM) #30 felt: 15.7 to 19.9 lbs. ASTM D 226 #30 (Type 2) felt: 26.4 to 27.3 lbs. Other relevant information from the article: "Asphalt felt, which has been around for over a hundred years, was originally a true cloth felt. "A long time ago, they used rag felt, which was cotton," says Dodie Webster, technical services manager at Tamko Roofing in Joplin, Mo., a manufacturer of asphalt felt. "But we can't get cotton rags any more." Since present-day asphalt felt is a paper product, the term "felt" is somewhat of a misnomer. "Unsaturated felt is basically composed of recycled corrugated papers mixed with sawdust," Webster says. Over the years, asphalt felt has also gotten lighter. "In the old days, it used to weigh 15 pounds per 100 square feet, but not anymore," says Allen Snyder, product engineer at CertainTeed, a manufacturer of asphalt felt. The main reason manufacturers make light-weight felts is because they're cheaper. "The whole issue comes down to price," says Ed Todd, technical manager at Atlas Roofing, an asphalt felt manufacturer in Atlanta. "This is a price-sensitive product," Todd says. Manufacturers now call their product "number 15" felt instead of 15-pound felt, and it weighs anywhere from 7 to 14 pounds per square. "ASTM has established two standards for asphalt felt. The less stringent standard is ASTM D 4869, which requires Type 1 (#15) felt to weigh at least 8 pounds per 100 square feet. The more rigorous standard, ASTM D 226, requires a minimum weight of 11.5 pounds per square. Most lumberyards stock only light-weight asphalt felt with no ASTM rating. "We sell a lot of the lightweight felts, the non-ASTM #15," says Webster. "It is probably our biggest seller." This type of #15 felt sometimes weighs only 7.6 pounds per square. There are a few regions where ASTM-rated felt is widely available, however, because of code requirements. "The most stringent felt market in the U.S. is Florida," says Ed Todd, of Atlas Roofing. "In Florida, at a minimum you must have 'ASTM D 4869' on the wrappers." "Asphalt felt is also available in a heavier version, commonly called 30-pound felt. This #30 felt is available in both the unrated grades and the ASTM-rated felts. ASTM standards refer to #30 felt as Type 2. The lightest unrated #30 asphalt felt is still heavier than the heaviest ASTM-rated #15 felt, making it a logical choice for concerned builders. "Asphalt felt has a permeance of only 5 perms when dry, but a much higher rating of 60 perms when wet. Fans of felt note one of its advantages over housewrap: If water gets behind felt - either due to a flashing leak or condensation from solar-driven moisture - the felt can soak up the liquid water and gradually dry to the exterior."
