- Q: I don't know why but I'm having a VERY difficult time finding the melting point of 1008 steel.
- It is still the same for 1008 steel. Go to the bottom and see the listing of the grades it covers. Since the only difference between the 1006 and 1008 steel is a few micro amounts of alloys and by far the greatest majority or main component is iron (99%), as a general melt temperature , 2750 F is the melt temperature at which the other alloys are added to the charge to fine tune the mix. Just like adding salt to distilled water actually lowers the boiling point of water, adding alloys to iron decreases the melting point of iron. The iron melts at 2800F, but once alloys to make the 1008 grade are added, it decreases melt temp to 2750F. Since the melting point of pure iron is 2800F, the temperature is actually decreased by adding these impurities of alloys. These alloys are tested while the mix is starting to come down from a pure melt, steel is sampled. and then alloys below are checked and added to make the 1008 steel. The steel is maintained at 2750 F so that the less volatile alloys don't boil off before combining with steel. Minimum Properties Ultimate Tensile Strength, psi 43,900 - 51,900 Yield Strength, psi 26,100 - 34,800 Elongation 42 - 48% Chemistry Iron (Fe) 99% Carbon (C) 0.08% Manganese (Mn) 0.6% max Phosphorus (P) 0.035% max Copper (Cu) 0.2% min Sulfur (S) 0.04%

- Q: I plan to buy a bushcraft knife ..The blade made up by damascus steel.My question is ,is damascus steel is very strong ?
- Pattern welded /damascus is too expensive to use as an everyday knife, as it can cost more than silver. It's best kept as a collection piece. You'd be stupid to keep it in your pocket or use it everyday. that would be a waste of money. Knives you use everyday might be lost or stolen, or they may get rusted, worn, or dirty..... ruining their value. From that point of view the strength or edge-holding ability means very little. Specifically, the bushcraft knife is pattern welded steel. True damascus or Wootz steel is something you'll only find in museums and private collections. they stopped making it several hundred years ago. Despite what many people have claimed, Wootz damascus was inferior to modern tool steels in every respect. It was a brittle, dirty material. It's legendary status has more to do with myth and storytelling. The reason they stopped making was undoubtaby because more modern methods came along that produced a more consistent product, more quickly and easily. Old technologies tend to be abandoned for good reasons. With pattern welded steel, about a dozen strips of two different grades of steel have been stacked, welded together, the twisted and forged to create interesting patterns. This more of an artistic process and doesn't improve the properties of modern steels. Pattern welded steel is for the most part, inferior to a homogenous blade made of a single grade of steel. First of all, PW is a handmade product which means there will be faults and oxide inclusions incorporated into the steel. The welding process is not perfect. Secondly, in the hardening and tempering process you end up with a compromise between the properties of the two different grades of steel. You end up with a product that is not quite as good as either steel would have been individually. The blade may either be too brittle or too soft.
- Q: Hey I just got a mini 14 manufactured in 1980. I also had some .223 Wolf steel cased HP rounds (about 200) that i could shoot throught it, but I was just wondering if its a bad idea to use this steel cased ammo...? Only the casing is steel i believe... and the bullet is copper jacketedthanks for your help
- I have had significant ejection and rechambering problems with Wolf semi-auto handgun ammo. It took forever to clean the fouling that the lacquered ammo generated too. I do not know about the rifle ammo, but I won't tempt fate over cheap rounds again.
- Q: What are the challenges in coil leveling for high-strength steel?
- One of the main challenges in coil leveling for high-strength steel is the material's inherent strength and hardness. High-strength steel is designed to have superior mechanical properties, which can make it difficult to manipulate and flatten during the leveling process. The high tensile strength and increased yield strength of the steel can cause it to resist deformation, leading to springback or permanent deformation issues. Additionally, the increased hardness of the steel can put more strain on the leveling equipment, potentially leading to wear and tear. Proper equipment selection, precise control of leveling parameters, and advanced process monitoring techniques are required to overcome these challenges and achieve accurate and consistent coil leveling results for high-strength steel.
