B4D Round Bars
B4D Round Bars is Alloy Steel Bar which is a Chromium, Molybdenum, Vanadium Alloy Steel widely used for high strength industrial applications. It is commonly used in power generation turbines in high strength fastener applications such as Bolt material. It is widely used in power generation turbines and industrial fastener applications, such as high-strength bolting for pressure vessels, valves, flanges, and fittings.
M/s Textron Steel and Alloys Stocks B4D Grade Round Bar in As Rolled, Annealed or Hardened Condition. Our bar-stock inventory carry both black finish and peeled bright finish round bar sizes from 10 mm up to 150 mm.
These B4D Round Bar are the starting material form to manufacture full threaded studs, double end studs, stud bolts, hex bolts, heavy hex bolts, socket head cap screws, set screws, countersunk screws, hex cap screws, threaded rods used for high tensile bolting in boilers, pressure vessels, valves, pipeline flanges, and fittings intended for use in high temperature, high-pressure service or other special purpose applications.
ASTM A437 / A437M is a Standard Specification for Stainless and Alloy-Steel Turbine-Type Bolting Specially Heat Treated for High-Temperature Service. Other Grades under this standard are B4B and B4C .
