Ismail Flanges, a well-known producer and supplier of Carbon Steel F70 Flanges with its headquarters located in Jakarta, Indonesia, offers strong and reasonably priced solutions for high-pressure and high-temperature applications. Under harsh operating conditions, our Carbon Steel F70 flanges are designed to provide outstanding strength, weldability, and dependability. These flanges meet international quality standards and are perfect for use in sectors like power generation, petrochemicals, and oil and gas. Here at Ismail Flanges, we prioritise customer satisfaction, prompt delivery, and precision manufacturing to make sure our customers get reliable, high-quality flanges that are customised to meet their unique project needs.
In controlled amounts, carbon, manganese, phosphorus, sulphur, and silicon make up the majority of carbon steel F70 flanges. Manganese increases toughness and wear resistance, while carbon increases strength. Tensile strength of 485–655 MPa, yield strength of 260 MPa, and elongation of roughly 20% are typical mechanical characteristics. These flanges are appropriate for pressure systems and high-stress situations because of their exceptional weldability, machinability, and impact resistance. Carbon Steel F70’s sturdy structure and mechanical stability guarantee reliable performance at both room temperature and higher temperatures.
