Alloy C276 has nickel, chromium and molybdenum in its chemical composition with added tungsten.It shows excellent corrosion resistance in various environments.The Hastelloy C276 tube also shows pitting and crevice corrosion resistance.They have a low carbon content which minimizes the risk of carbon precipitation during welding.The EN 2.4819 square tubing shows good resistance to elevated temperature conditions that can go up to 1038°C.
They possess good mechanical properties, with a minimum yield strength of 345 Mpa.Nickel C276 condenser tubes can achieve strength by undergoing the pilger process.They can also maintain their toughness at cryogenic temperatures.The 2.4819 Hastelloy C276 gas tube can be hot worked within the temperature range of 870-1230 °C.They have a high work hardening rate, so annealing is a recommended process.
The price of alloy C276 tube in India can vary with the suppliers you choose.Firstly, the raw material prices depend on the market conditions and it also changes with the quality.The suppliers also have their internal pricing strategies and the demand for the UNS N10276 cold drawn tube also determines the price.
Now other factors like quantity ordered, added requirements like surface treatments, testings, etc.and delivery location also determine the price.You should always do your research and go for reputed suppliers like Regent Steel & Engineering Co., who offer quality Hastelloy alloy C276 boiler tubes at competitive rates.
