Known for precision engineering and strict quality control, Aung Metals delivers products that meet international standards for durability, strength, and performance. The Stainless Steel 440C Hex Bar is designed for demanding industrial applications where toughness and corrosion resistance are critical. With modern manufacturing technology and a dedicated quality assurance process, Aung Metals ensures consistent mechanical integrity and finish, making it a trusted name across multiple sectors in Myanmar and beyond.
The Stainless Steel 440C Hex Bar is a high-carbon martensitic stainless steel containing approximately 1.0% carbon, 17% chromium, and trace amounts of manganese, silicon, and molybdenum. It offers an exceptional combination of hardness and corrosion resistance, especially after heat treatment. The material achieves a tensile strength of about 760–1000 MPa and can reach a Rockwell hardness up to 60 HRC when properly hardened. This balance of strength, wear resistance, and corrosion protection makes it ideal for precision components requiring superior performance under mechanical and environmental stress.
