What is 1045 steel?
AISI 1045 is a commonly used medium carbon steel known for its balance of strength, toughness and weldability. With approximately 0.45% carbon it can be hardened through heating and quenching.
What are its typical applications?
1045 plates are widely used for machine parts, small tools, shafts and general fabrication where better formability is required than high-carbon steel. It's also ideal for applications involving welding, cutting or machining.
How do mechanical properties compare to other steels?
Yield strength of 1045 plate ranges from 35-65 ksi allowing it to be readily machined or formed. It has greater strength than low-carbon grades but higher toughness than most tool steels. Elongation typically reaches 20-30% for good ductility.
Can 1045 plate be heat treated?
Yes, 1045 responds well to common heat treating processes. Hardening involves heating to 1550-1650°F range then oil or water quenching to attain RC 40-50 hardness levels. Tempering then diffuses the carbon for improved toughness.
What thickness and size ranges are offered?
We stock 1045 plate in thickness from 1/8" up to 4" and widths ranging 6-72". Longer length capabilities are available through blanking from our full size inventory coils and plates.
How is 1045 processed and certified?
All plates are produced on slabbing/hot rolling lines with strict quality assurance. Certifications include material test reports to verify chemical composition and mechanical properties meet ASTM A515 standards.
