A4-80 stainless steel bolts are premium-grade fasteners designed for industries requiring superior strength, corrosion resistance, and durability. These bolts are widely utilized in marine, construction, and chemical processing industries, where they must withstand harsh environmental conditions.

 A4-80 stainless steel bolts derive their classification from two components:

A4 indicates that the bolt is made from the SS 316 family, austenitic stainless steel known for its exceptional corrosion resistance. 80 denotes a minimum tensile strength of 800 MPa, ensuring robustness and reliability.

 Bigboltnut  fasteners adhere to ISO 3506-1 standards, guaranteeing top-tier performance across industrial sectors that demand high-strength fastening solutions.

 Material Composition and Chemical Properties

The composition of A4-80 stainless steel bolts enhances their resilience against rust, acids, and chloride-rich environments, making them ideal for use in marine and chemical processing applications.

 Key Chemical Elements:

·         Chromium (16-18%) – Enhances corrosion resistance.

·         Nickel (10-14%) – Increases mechanical stability.

·         Molybdenum (2-3%) – Prevents pitting and crevice corrosion.

·         Carbon (≤ 0.08%) – Balances strength while reducing brittleness.
