ASTM A830 1045 Plate

This medium‑carbon steel plate conforms to ASTM A830 1045 chemistry and is supplied for applications that require higher strength and good machinability. The “10” indicates a plain carbon steel and the “45” denotes an approximate 0.45% carbon level typical of 1045 grades, giving a balance of strength, hardness and wear resistance.

Key characteristics

• Composition: medium‑carbon steel (approx. 0.45% C), plain carbon grade (ASTM A830 1045 chemistry).
• Mechanical properties (typical): minimum yield ~45 ksi; average tensile ~90 ksi; elongation ~16%.
• Hardness (typical): Brinell ~163; Knoop ~184; Vickers ~170; Rockwell B approximately 84.

Common applications

• Components requiring strength and wear resistance: gears, shafts, axles, bolts, studs, sprockets
• Heavy‑duty equipment: crushing equipment, pulverizers, precision conveyor system parts
• Machine building, fabrications and other machining applications
• Suitable for flame or induction hardening when increased surface hardness is required

Processing and services available

• Plate cutting: oxy‑fuel flame cutting and plasma cutting on four 40 ft plate cutting tables (cut‑to‑size available)
• Heat treatment: stress relieving and annealing
• Grinding: Blanchard grinding and surface grinding for flatness and finish control
• Machining & fabrication: CNC machining and complete fabrication services
• Quality documentation: Mill certifications and Material Test Reports (MTRs) and heat‑cycle records available on request

Ordering notes

• Specify required dimensions, thickness, surface finish and any required heat treatment or certification when requesting a quote
• Precision ground and machined plate supplied to drawing tolerances upon request

If you require specific mechanical or chemical certifications, custom cutting, or special processing, include those requirements with your inquiry so the supplier can confirm capability and delivery.
