Carbon Steel A307 Fasteners
Fasteners are an integral part of any manufacturing industry. They keep the machinery and equipment together and enhance their stability and durability. Among various types of fasteners available in the market, the Carbon Steel A307 Fasteners are popularly used due to their robustness and resilience. The Carbon Steel A307 Fasteners are versatile and economical fasteners widely used in various industries. They have excellent physical and mechanical properties that are ideal for high-stress applications.
Features of Carbon Steel A307 Fasteners
The Carbon Steel A307 Fasteners are low-cost fasteners that are easy to machine and hot-form. Due to their low work-hardening rate and flexibility, they are used in various industries like chemical, petroleum, steam, gas, water, and power generation. The bolts, nuts, and screws made of carbon steel A307 are galvanically compatible with other materials and do not trigger dissimilar metal corrosion. They have a high resistance to wear and tear due to the hard surface layer formed after fastener servicing.

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.
Applications of Carbon Steel A307 Fasteners
Carbon Steel A307 Fasteners are widely used to manufacture flanges, pipe fittings, valves, and other piping components. They are also used in high-temperature power generation plants, petroleum refineries, chemical plants, and paper mills. Due to their excellent corrosion resistance, they ensure the safe and secure transportation of crude oil, natural gas, and other petroleum products.
Physical & Mechanical Properties of Carbon Steel A307 Fasteners
Carbon Steel A307 Fasteners have excellent physical and mechanical properties. They have a density of 7.8gm per cubic cm, a melting point of 1432°C, and a thermal conductivity of 24 W/mK. They have a tensile strength of 485 MPa and a yield strength of 250 MPa. Their elongation at break is 20%, and their hardness in the annealed condition is Brinell 187.
