Carbon Plate - C1020 / C1045 - ASTM A 830

General requirements for delivery
Material shall conform to the requirements of ASTM A 6.

The ASTM A 830 specification covers 48 standard chemistries. Oliver Steel offers two of these chemistry-only plate grades. C1020 offers better machinability than the normal low carbon commercial alternative of A36. C1045 provides higher strength and hardness levels and is readily flame hardened. Both have a much lower cost than free-machining grades of similar carbon levels.

This specification covers structural quality carbon steel plates furnished to chemical composition requirements only. There are no tensile requirements or other mechanical property requirements for this specification.

ASTM A 830 was first issued in 1984; prior to that the C1020 and C1045 chemistries were defined by AISI specifications.
