Frequently Asked Questions

Learn more about A830-1020 steel plate.
A830-1020 and A830-1045 are both carbon steel plate grades within the ASTM A830 specification family, but they are used for different performance needs. A830-1020 has lower carbon content, which makes it better suited for applications that require ductility, formability, machinability and weldability. A830-1045 has higher carbon content and is typically used when a part requires greater hardness, strength or heat-treating potential.
ASTM A830-1020 steel plate is used for machined and fabricated parts that require low-carbon steel with good ductility, formability, machinability and weldability. Common uses include couplings, studs, bolts, structural components, base plates, machine frames and general-purpose machine parts. It may also be used for shafts, gears and axles when workability is more important than higher hardness or heat-treating potential.
In 1020 steel, the “10” refers to a plain carbon steel, while “20” refers to the approximate carbon content. This lower carbon content helps make A830-1020 more ductile, formable and weldable than higher-carbon grades such as A830-1045.
ASTM A830 steel grades are furnished primarily to chemical composition requirements, so A830-1020 is not always routinely tested for mechanical properties unless testing is requested. If a project requires specific yield, tensile, elongation or hardness values, those mechanical property requirements should be requested when the plate is ordered.
