What are Annealed, Hot-Finished and cold-drawn in SA 479 gr 304 material?
A SA 479 gr 304 Bars is usually processed in annealed, hot finished and cold drawn conditions. The robust ASTM A276 Type 304 hot rolled bar is manufactured at high temperatures till it reaches its recrystallization limit. These bars have slightly rounded edges with small distortions. During the annealing process, the AMS 5639 Bar is heated at specific temperatures and later cooled. Annealing helps in softening the metal and improving its ductility while reducing its brittleness.
The 304 Stainless Steel Cold Rolled Bar is processed soon after the hot rolling process at room temperature. These bars have an excellent surface finish and have close tolerances. The SA 479 304 Cold Drawn Round Bar has better strength and enhanced corrosion resistance properties compared to the other two. The ASTM A479 Type 304 Polished Bar is a product of the cold forming process and has a shiny surface finish.
Difference between ASTM A276 Type 304 condition a and condition b
The ASTM A276 Type 304 is available in either condition a or condition b. ASTM A276 Type 304 condition a is an annealed metal that is highly resistant to corrosion in harsh environments. This SA 479 gr 304 Bar condition a grade is very ductile and is common in the automotive, marine, oil, aerospace, and petrochemical industry. The condition b SA 479 tp 304 Rounds is also annealed and is more stronger and ductile than condition a. This is accomplished via the cold working process. An SS 304 Black Bar is common in heavyweight fasteners, carabiners, linkage devices, the automotive industry, etc.
Why 304 Stainless Steel Round Bar is a popular grade? Read more about application and advantages
The SS 304 grade is the most common grade used in producing a stainless steel round bar. The ASTM A276 UNS S30400 grade has excellent chemical content, giving it outstanding resistance to corrosive and reducing affluents. The round bars of this grade have excellent toughness in elevated as well as low temperatures.
The austenitic SUS 304 rod has outstanding welding qualities and the raw materials required to manufacture the grade are readily available. This makes it a popular grade in the industry. The SA 276 304 Rectangular Bars is commonly seen in a variety of home and commercial applications. These bars are used in the food, domestic tools, and architectural industry. The A479 Gr 304 Forged Bars is also seen in chemical containers, heat exchangers, mining systems, etc.
