With a strong background in precision engineering and a commitment to quality, this company delivers bars that guarantee outstanding durability, reliability, and performance. Alloy Steel F91 Bars are well-known for their exceptional strength, heat resistance, and corrosion resistance, making them perfect for tough environments. Phanuphong Steel is dedicated to delivering products on time, meeting the needs of industries both in Thailand and around the globe with trusted engineering and material solutions.
These Alloy Steel F91 Bars are primarily made up of chromium, molybdenum, and vanadium, with carefully controlled amounts of carbon, manganese, phosphorus, and sulfur. This specific alloy mix provides remarkable creep strength, stability at high temperatures, and resistance to corrosion. In terms of mechanics, these bars boast a tensile strength ranging from 585 to 760 MPa, a yield strength of about 415 MPa, and an elongation of roughly 20%. They also exhibit impressive hardness, toughness, and wear resistance, even in high-temperature settings. Their perfect blend of strength, durability, and thermal resistance makes them ideal for high-pressure and high-temperature industrial applications.
