ASTM A694 Carbon Steel Grade F42/46/52/56/60/65/70 Bars are high strength, low alloy steel bars that meet specific mechanical properties and chemical composition specifications set out by ASTM International standards. They are commonly utilized by industries where robustness, corrosion resistance and resilience to impact are of primary concern in applications like structural components or machinery components that must withstand extreme loads such as machinery production lines.
Each grade within the ASTM A694 specification corresponds to specific mechanical properties and chemical composition tailored to suit various applications: F42: This grade features a minimum yield strength of 42ksi (kilo-pound per square inch), making it appropriate for applications requiring moderate strength and toughness.
ASTM A694 Carbon Steel Grade F42/46/52/56/60/65/70 Bars are known for their outstanding strength-to-weight ratio, excellent weldability, and corrosion and abrasion resistance and make ideal components for various industries such as construction, oil & gas exploration/production/pipelines petrochemistry power generation offshore drilling etc.
These bars are widely employed in fabricating structural components like beams, columns and trusses as well as in building heavy machinery, equipment and pipelines. Furthermore, their high strength and corrosion-resistance make them crucial components for operational reliability and safety in manufacturing applications such as pressure vessels, valves, flanges and fittings.

Melting and Casting
Steel and alloying metals are loaded into an electric arc furnace. Once in the furnace, the metal is heated to a specific temperature above its melting point, usually in excess of 2800°F.
Forming
Most cast steel is formed by hot rolling—the slab, bloom, or billet is heated and passed through large rollers, stretching out the steel into a longer, thinner form.
Heat treatment
Heat treatment strengthens rolled Carbon Steel by recrystallizing the deformed microstructure. Most Carbon Steel is heat treated by annealing.
Descaling
A rolled piece of Carbon Steel acquires a layer of oxidized “mill scale,” which needs to be washed away to restore a shiny surface finish.
Cutting or Machining
Carbon Steel is cut to a specified shape and size. The Carbon Steel can be sheared with circular knives, sawed with high-speed blades, or blanked with punches.
