Stainless Steel A4-70 Flat Washer:
Material: A4-70 flat washers are made from stainless steel of grade A4-70. The "A4" denotes the stainless steel grade, which is equivalent to 316 stainless steel. The "70" indicates the minimum tensile strength in megapascals (MPa), which, in this case, means the washer has a minimum tensile strength of 700 MPa.
Corrosion Resistance: A4-70 stainless steel offers excellent corrosion resistance, particularly in marine and highly corrosive environments. It can resist rust and corrosion, making it suitable for outdoor, maritime, and chemically aggressive applications.
Design: Flat washers have a simple, flat, and circular design with a central hole. They are used to distribute the load of a fastener (such as a bolt or screw) over a larger surface area, reducing the pressure on the material and helping to prevent damage.

Applications: A4-70 Flat Washers are employed in various industries, including construction, marine, automotive, and manufacturing. They are used wherever a standard flat washer is needed to evenly distribute loads, protect surfaces, and prevent fasteners from loosening.
Stainless Steel A4-70 Spring Washer:
Material: A4-70 spring washers are also made from stainless steel grade A4-70, which is the equivalent of 316 stainless steel with a minimum tensile strength of 700 MPa.
Corrosion Resistance: A4-70 stainless steel offers excellent corrosion resistance, making A4-70 spring washers suitable for outdoor and marine applications where exposure to moisture and saltwater is a concern.
Design: Spring washers, also known as split washers, have a unique design with a split or cut that allows them to exert spring-like tension when compressed. This tension helps prevent fasteners from loosening due to vibrations or dynamic loads.
Applications: A4-70 Spring Washers are commonly used in machinery, automotive, and industrial applications where maintaining tension in fasteners is critical. They are particularly useful in situations where there is a risk of loosening due to vibrations or thermal expansion and contraction.
When using A4-70 stainless steel washers, it's essential to match them with compatible A4-70 stainless steel fasteners to ensure consistent corrosion resistance and mechanical properties. Proper installation techniques and torque values should also be followed to achieve the desired performance and load distribution.
