- Q: Do any tour players use steel shafted woods? And are there any real advantages to having steel shafted woods? I have only played with one person to use steel shafted woods, he tells me thats because he cant hit it straight with graphite, however he is a very short hitter.
- Graphite shafts are generally better for the amateur golfer. Graphite shafts are more forgiving than stell shafts. With graphite shafts, it is easier to get the ball in the air, and keep your ball trajectory always with good height. For SOME above average golfers and tour professionals, steel shafted woods find their way into their bags. This is because steel shafts have the ability of being more precise in terms of direction. However, to hit steel shafted woods, you need a lot of power and a slightly faster than normal tempo. Point is, if your a golfer that plays this sport for the leisure, or don't want to be stressed, take the graphite shafts. But if you're a single-digit handicapper, and feel you're physically fit ALL THE TIME, then go ahead and try the steel shafts.
- Q: How are steel coils processed for heat treatment?
- Steel coils are typically processed for heat treatment by first being uncoiled and then cleaned to remove any dirt or scale. The coils are then heated to a specific temperature, which is determined based on the desired properties of the steel. This temperature is maintained for a specific period of time to allow for the desired transformation of the steel's microstructure. After the heat treatment process is complete, the coils are cooled either slowly or rapidly, depending on the desired properties. This allows the steel to be hardened or softened as required. Finally, the coils are recoiled and prepared for further processing or shipment.
- Q: How are steel coils used in the production of heating and cooling systems?
- Steel coils are used in the production of heating and cooling systems as they serve as the primary component for heat transfer. These coils are designed to efficiently transfer heat or cool air, allowing for the effective regulation of temperature in heating and cooling systems.
- Q: What are the different types of steel coil recoiling methods?
- There are three main types of steel coil recoiling methods: slit edge recoiling, mill edge recoiling, and oscillated recoiling.
- Q: Can we construct a barn using steel and will it be a durable one?
- sure , steel barns are all over the place...the common brand of steel buildings around here are Butler Buildings...
- Q: Some stainless steel products are as shiny as chrome. Can all/most stainless steel be polished to a chrome like luster.
- The nickel and chromium content do have some effect on shine. But mostly they effect the corrosive and rust resistance property's of the stainless steel. 300 series stainless steel such as 304e or 316e will not rust like 400 series 416e eventually will. All types of stainless steel can achieve a bright shine. The key is using jewelers rouge and the correct buffing wheel. Avoid scotchbrite if you want shine. It will clean your stainless steel but it will not shine it the way you want. Miketyson26 (certified tig welder)
