A276m Hex Bar and A276 bright bar suppliers in UAE
What is ASTM A276 & ASTM A276m ?
ASTM A276 & ASTM A276m is a standard specification of stainless steel bars of different shapes. The ASTM A276 Round Bar is a common circular cross section bars that is defined by its composition and mechanical requirements as per stainless steel. The A276 round bars offers superior strength and tolerances. They can be processed in either hot or cold rolling procedures.
What is purpose of annealing A276 round bar ?
The A276 round bars is annealed to make it more formable and ductile. Annealing the A276 stainless steel rounds help improve its workability and toughness while reducing its hardness. This makes the bars more ductile and easily machinable. In addition, the A276 hex bar can be annealed to increase its electrical conductivity.
Difference between ASTM A276 Round Bar, Shafting, and Drill Rod
- ASTM A276 round bar is a long cylindrical metal bar. These bars are available in different diameters and provide support and strength to the material. They are generally hot or cold rolled.
- Shafting is also referred to as turned ground bars that are produced with fine precision and high quality. The A276 stainless polished bars has a straight surface with a flawless finish.
- ASTM drill rod is manufactured from tool steel having a tight diameter tolerance. They are tempered before machining and are fabricated in square shapes. These rods punch holes into steel, wood, etc.
How do you calculate shear stress in a ASTM A276 stainless steel rod?
The shear strength of an ASTM A276 stainless steel rod is 60% of the tensile strength of the material.
Hot Finished vs Cold Finished ASTM A276 bar
- The ASTM A276 hot rolled bar is produced at high temperatures till it reaches its recrystallization limit. A276 ss cold drawn round bars is processed at room temperature soon after the hot rolling process.
- Hot rolled A276 steel rectangular bars requires lower process time and are cheaper than cold finished bars.
- Cold finished A276 bright bars exhibits better strength and superior finish compared to hot rolled bars.
