Phanuphong Steel and Plates, a top-notch manufacturer and supplier based in Bangkok, Thailand, specializes in high-quality Alloy Steel AISI 8620 Bars that are crafted to meet strict industrial standards. Known for their precision, durability, and consistency, these bars are made using cutting-edge metallurgical techniques, guaranteeing reliable performance even in tough applications. With a strong focus on both local and global markets, Phanuphong Steel delivers dependable solutions for the automotive, machinery, and engineering industries. Their dedication to quality, prompt delivery, and outstanding customer service makes them a go-to choice for clients looking for premium alloy steel products in Thailand and beyond.
Alloy Steel AISI 8620 Bars are primarily composed of carbon (0.18–0.23%), manganese (0.60–0.80%), chromium (0.40–0.60%), nickel (0.40–0.70%), and molybdenum (0.15–0.25%). This blend results in a well-rounded mix of toughness, hardness, and wear resistance. Mechanically, these bars boast a tensile strength between 620 and 850 MPa, a yield strength of 370–510 MPa, and an elongation of about 15–20%. Their hardenability allows for effective heat treatment, yielding a robust, durable core with a tough, wear-resistant exterior. Additionally, the bars show impressive fatigue strength, impact resistance, and dimensional stability, making them ideal for applications that demand both strength and toughness under pressure.
