ASTM A276 is a standard specification for stainless steel bars and shapes. However, it also has relevance in the world of bolts. When it comes to ASTM A276 condition A, it refers to the specific conditions for the manufacture of stainless steel bolts.
This means that bolts made from a276 material must meet the specific mechanical and chemical properties outlined in the ASTM A276 specification. Astm A276 Stainless Steel Bolts are commonly used in applications where high strength, corrosion resistance, and durability are critical. There are industries that require strong and corrosion-resistant material for fasteners. Industries like the oil and gas industry have to deal with high corrosion resistance while the aerospace industry has to deal with high vibrations and requires strength.
ASTM A479 and ASTM A276 are both established standards for stainless steel bars and shapes. While they can sometimes be used interchangeably, there are significant distinctions between them. These differences are primarily due to the subtle variations in materials like martensitic, austenitic, and ferritic steel types, which greatly impact their respective costs.
ASTM A276 Condition A is a comprehensive specification encompassing various stainless steel shapes and dimensions, such as round, square, hexagonal, and flat bars. It also covers different material conditions, including Condition A and Condition H. Conversely, ASTM A479 is a standard specifically targeting stainless steel bars and shapes intended for pressure vessels and general applications.
Another difference between the two is that ASTM A479 requires additional testing, such as intergranular corrosion testing and Charpy impact testing, to ensure the material meets the necessary mechanical properties. This testing is not required in ASTM A276. Siddhagiri metals and tubes provide you with products of all your requirements and specification.

In summary, ASTM or ASME SA276 is a specification typically employed in the production of stainless steel bolts, while ASTM A479 is more frequently used for creating stainless steel bars and shapes intended for pressure vessels and general applications. Although these two products can often be used interchangeably due to their similarities, they possess notable differences. The primary distinctions between them lie in their testing requirements and the variety of materials covered within each classification.
