ASTM A479 stainless steel rod and A479 material suppliers in UAE
What is ASTM A479?
ASTM A479 grade covers standard specifications of hot and cold finished bars. The ASTM A479 bar is primarily utilized for pressure vessel and boiler construction. These bars are shaped in round, square, rectangular, hex, and other shapes. ASTM A479 Round Bar has a circular cross section and cover 4 grades of stainless steel including ferritic, austenitic, austenitic-ferritic, and martensitic specification.
The A479 round bar has enhanced strength and outstanding corrosion resistance properties. These bars are versatile and very malleable. A479 steel rectangular bar is a long flat bar having a rectangular cross section. These bars have good tolerance and are utilized in support and bracing equipment. The ASTM A479 flat bar is furnished in conditions A, B, T, and S. They are used in construction, manufacturing, mining, fabrication, and other industries. ASTM A479 condition b finish is annealed and severely cold worked. These bars are very strong and hard but are less ductile.
The ASTM A479 square bar has a square cross sectional area. These bars are commonly used for general repairs, assembly, and manufacturing units. A479 hex bar has a unique 6-sided shape that allows them to move easily in the system.
ASTM A479 Forged Bar vs Rolled Bar
The ASTM A479 forged bar is produced as metal is heated and hammered to get it in the right shape. In the rolling method, the A479 material is passed through rollers to reduce its thickness to the required size. Rolling can be done in both hot and cold processing types. A479 forged bar has complete flow lines, while the integrity of the metal streamline is destroyed after rolling. The degree of deformation in forging is much greater than in rolling. The cost of processing A479 stainless steel rounds is much higher than that of rolling.
What is the shear strength of A479 material?
The shear strength of ASTM A479 stainless steel rod is generally 60% of the tensile strength of the steel material.
Difference between Cold Drawn, Bright Drawn, Polished ASTM A479 bar
Cold drawn, bright drawn and polished bars are finishing processes of steel. The A479 SS cold drawn round bar is processed at room temperature, giving it superior strength and tolerance in harsh conditions. The A479 bright bar is the same as cold drawn bars, but they have a better surface finish exhibiting a glowy finish. The A479 stainless polished bar has excellent dimensional accuracy with a seamless surface finish and roundness.
What are the types of A479 round bar annealing?
Annealing is the process of transforming the A479 round bar to improve its plasticity and reduce the hardness of the material. There are 7 types of round bar annealing offered by the A479 rounds bars. This includes complete, isothermal, incomplete, spherification annealing, diffusion, stress relief, and recrystallization annealing.
What is Peeled and Reeled ASTM A479 stainless steel bar?
ASTM A479 peeled and reeled stainless steel bars are bars having a smooth and polished surface. These steel bars are subjected to cutting tools to make the surface free from any defects.
