Stainless Steel A4-70 Hex Bolt

The excellent strength and corrosion resistance of stainless steel A4-70 hex bolts make them fasteners for demanding settings. These bolts satisfy strict quality criteria since they follow ASTM A193 and ASME SA 193 standards. With a tensile strength of 700 MPa, the A4-70 grade qualifies for use, calling for dependable and long fastening. A4-70 bolts have composition calls for chromium (16–18%), nickel (10–14%), and molybdenum (2–3%), hence improving their resistance to corrosive agents—particularly in chemical and marine environments.


Here are some key features and characteristics of A4-70 stainless steel hex bolts:


Material Composition: A4-70 stainless steel is primarily composed of iron, chromium, nickel, and molybdenum. This combination of elements imparts excellent corrosion resistance and mechanical strength.


Corrosion Resistance: A4-70 stainless steel is highly resistant to corrosion and rust, making it suitable for use in harsh environments, including marine applications. Its corrosion resistance is a result of the chromium content, which forms a protective oxide layer on the surface of the bolt when exposed to oxygen or moisture.
