Latham Steel, a trusted manufacturer and supplier located in Hamilton, New Zealand, specializes in high-quality SAE 1045 Steel Sheets and Plates. These products are crafted for medium-strength, high-wear mechanical and industrial applications. Renowned for their excellent machinability, toughness, and precise dimensions, Latham Steel guarantees that its SAE 1045 offerings adhere to rigorous international standards. This medium-carbon steel grade is a popular choice for parts that need enhanced hardness and strength compared to low-carbon steels. With dependable supply, precise processing, and strict quality control, Latham Steel plays a vital role in supporting New Zealand’s engineering, fabrication, automotive, and machinery sectors with durable and cost-effective SAE 1045 steel solutions.
SAE 1045 Steel Sheets and Plates are composed of about 0.43–0.50% carbon, along with manganese, phosphorus, sulfur, and small amounts of silicon. This medium-carbon makeup gives them significantly greater strength and hardness than low-carbon steels while still allowing for good machinability. Their mechanical properties include high tensile and yield strength, excellent wear resistance, and improved toughness. SAE 1045 responds well to heat treatment methods like quenching and tempering, which enhance hardness and fatigue resistance. It maintains stable mechanical performance even under moderate to heavy loads, making it ideal for demanding mechanical components.
