BS 4276 provides a set of guidelines that consist of specifications for hard metal for wire, bar, and tube drawing dies.
BS 4276 specifies eight types of Hard Metal grades for use in wire, bar, and tube drawing dies and lays down the hardness, composition, and grain size required for the Hard Metal for these grades.
BS 4276 has been prepared under the authority of the Mechanical Engineering Industry Standards Committee and with the fullest cooperation of dying users and manufacturers, and the manufacturers of wire drawing machinery.
Note: Special Hard Metal grades in which some or all of the cobalt is present as eta-phase or in which binder metals other than Cobalt are used, are excluded from this specification.
BS 4276 on Hard metal for wire is useful for:
Wire drawing procedure involves close diameter wire production of tolerance by drawing descaled hot rod through a die. These dies are produced from hard materials like carbide, tungsten, etc.
BS 4276 standard is a set of guidelines for vehicle manufacturers with specifications for hard metal for wire, bar, and tube drawing dies.
BS 4276 specifies requirements for Hard Metal grades generally used in the manufacture of dies for cold drawing wire, bar, and tube in ferrous and non-ferrous metals and alloys.
BS 4276 guidelines help the buyers to use hard metal for wires for a strong and long-lasting product.
