1045 Steel Plate


1045 Steel General Information

1045 steel plate is often used to manufacture large sprockets and steel gears for the paper industry and other processing industries. Coal, Iron, rock, stone, gravel, and even cement are processed and transported every day using parts made from 1045. Engineered systems such as moving systems, crushing systems, curing and drying systems handle enormous tonnages of raw materials while processing them into smaller, more refined, or mixed applications.

Heavy plate inventory1045 plate is a Chemistry plate, meeting the chemistry make-up listed below. The “10” designates a basic plain carbon steel and “45” designates the approximate carbon content.

Like the 1020 specification, the 1045 steel specification is included in the ASTM 830 family of specifications. The ASTM A830 specification covers approximately 48 Chemistry plates, ranging from G10060 – G15520, non-inclusively. Among other mills, ArcelorMittal and Nucor manufacture plates to the ASTM A830 specification.

Precision Grinding works with design engineers, job shops, parts and machine manufacturing companies, and even processing plants themselves to manufacture custom steel component parts used in the processing equipment that services these industries. Besides offering higher-strength steels such as 1045, we also manufacture mining equipment parts and other wear plates for systems requiring wear resistance in addition to high strength properties. We manufacture steel parts according to specifications as laid out by the mechanical engineers for fabrication job shops and for the plants themselves.

Common Uses of 1045 Steel Plate

Common uses of 1045: gears, shafts, axles, bolts, studs, sprockets, crushing equipment, pulverizers, & precision conveyor system parts, and other machine parts.

1045 steel plate is also suitable for flame and induction hardening.
