Corrosion Resistance of Carbon Steel A307 Fasteners

Carbon Steel A307 Fasteners are designed to resist corrosion. The presence of nickel in A307 improves its corrosion resistance as it shrinks the grain size, increasing fatigue life and tensile strength. Carbon Steel A307 Fasteners, when exposed to elevated temperatures, are susceptible to stress-corrosion cracking. To avoid any mishap, choosing a fastener with high nickel content, low hardness, and stress-relieved forging is ideal.

Chemical Composition of Carbon Steel A307 Fasteners

The chemical composition of Carbon Steel A307 Fasteners makes them ideal for many applications. They comprise elements like Carbon, Manganese, Phosphorus, Sulfur, Silicon, Copper, Chromium, Molybdenum, and Nickel, which impart strength and durability to the fasteners. Carbon Steel A307 Fasteners have a minimum yield strength of 36 ksi and are forged at a temperature of 2200°F with a cool-in-air process.
