Phanuphong Steel and Plates, a prominent manufacturer and supplier located in Bangkok, Thailand, is known for its top-notch Alloy Steel AISI 4145 Bars. These bars are celebrated for their precision and durability, crafted to meet strict industrial standards, ensuring they perform exceptionally well across a variety of applications. Phanuphong Steel merges cutting-edge production methods with thorough quality control, delivering products that boast impressive strength, toughness, and reliability. With a strong focus on customer satisfaction, the company helps industries enhance their operational efficiency and achieve long-lasting performance, making it a trusted ally for Alloy Steel solutions not just in Thailand, but throughout the Southeast Asian region.
Alloy Steel AISI 4145 Bar is primarily made up of carbon, chromium, and molybdenum, which work together to boost its strength, hardness, and resistance to wear. The carbon content gives it remarkable tensile strength, while chromium enhances its corrosion resistance and hardenability. Molybdenum adds to its toughness and strength at high temperatures. Typically, this steel has a tensile strength that ranges from 850 to 1000 MPa, a yield strength of about 655 MPa, and hardness levels between 217–269 HB, depending on the heat treatment it undergoes. It also shows good fatigue resistance, making it a great choice for components that face repeated stress. This blend of mechanical properties ensures it remains reliable in demanding industrial settings.
