Which heat treatments are used for an SA 276 Gr 304 Threaded Bars?

Mills customarily subject an SA 276 grade 304 threaded bar to annealing for ductility (Condition A). You can select hardening, tempering, strain hardening, or ageing for a threaded bars. An SA 276 TP 304 cold drawn round bars in Condition B is severely cold-worked for high-strength building and plumbing.

What is the surface finish of an A276 Gr 304 Polished Bar?

Polishing achieves a smoother, reflective surface, protecting an ASTM A276 Grade 304 polished bar from contamination and oxidation. A polished bars differs from a mirror finish (buffing, brightening). Customers can opt for BA or rough-turned finish. An SA 276 304 black bar is darker and matt. A black bars differs from a bright one (cold-drawn and shinier)

What are the top 4 applications of an SA276 304 square bar and an SA276 304 hot rolled bar?

A hot rolled bars comes in square, round, flat, and hex shapes.

  • Square bars fulfill architectural roles like railings and barriers.
  • An ASTM A276 Grade 304 cold rolled bar works in the shipbuilding and automotive sectors.
  • A rod and a bars (higher strength and durability) work in construction.
  • An ASME SA276 304 rod works in machinery, axles, and shafts.

What are the different tolerance levels for an ASTM A276 type 304 bar?

Exacting tolerances prevail for cold-rolled and an ASTM A276 304 hot rolled bars. Allowed diametrical variations are +/-0.070mm for a round bars (<18mm). A flat cold rolled bars, square, and hex ones permit +/-0.110 and +/-0.090mm, respectively. Length variations in a cold drawn round bars can be +/-2mm.
