A2-70 is a specific grade of stainless steel that is commonly used for stud bolts, screws, and other stud bolts. Let's break down the features, applications, and corrosion resistance of A2-70 stainless steel:
Features:
Material Composition: A2-70 stainless steel is primarily composed of iron (Fe), chromium (Cr), and nickel (Ni). The "A2" designation is a reference to the AISI (American Iron and Steel Institute) 304 stainless steel grade, which is equivalent to the SAE (Society of Automotive Engineers) 304 stainless steel grade. The "70" represents the minimum tensile strength in megapascals (MPa), which is approximately 700 MPa.
Corrosion Resistance: A2-70 stainless steel offers good corrosion resistance, especially in moderately corrosive environments. Its high chromium content (around 18%) forms a protective oxide layer on the surface, which helps prevent rust and corrosion. However, it may not be suitable for highly corrosive or marine environments.
Strength: A2-70 stainless steel has a moderate tensile strength, making it suitable for applications where high strength is not a primary requirement. Its strength is sufficient for many general-purpose fastening applications.
Machinability: A2-70 stainless steel is relatively easy to machine, making it suitable for a variety of manufacturing processes, including threading for stud bolts.

Applications:
A2-70 stainless steel stud bolts and fasteners are used in a wide range of applications, including:
Construction: They are commonly used in construction projects for joining structural components, such as steel beams, frames, and supports.
Machinery: A2-70 stud bolts are used in the assembly of machinery and equipment, where corrosion resistance and moderate strength are required.
Automotive: They find use in the automotive industry for various fastening applications, including engine components and body panels.
General Fastening: A2-70 stud bolts can be used in a variety of general fastening applications, including those in industrial and household settings.
Corrosion Resistance: While A2-70 stainless steel offers good corrosion resistance in many environments, it may not be suitable for highly corrosive conditions such as marine environments with exposure to saltwater. In such cases, a higher-grade stainless steel, like A4-70 (AISI 316 stainless steel), which contains more nickel and molybdenum, is typically preferred.
To preserve the high standards of our selection of industrial stud bolts, we have always adhered to a systematic quality management process.
Our staff of experts is vibrant and talented, and they have always been our largest supporters and contributors to our success. Our vision is to create a world of stud bolts.
