ASTM A240 310s User Cases: A Common Choice for International Projects and Extreme Operating Conditions
- A multinational metallurgical company specified ASTM A240 310s plate for a 1200°C hot-rolling reheating furnace project in Southeast Asia. The equipment has operated for three years without oxidation damage, successfully passed local ASTM standard audits, and achieved a 100% project cashback rate.
- A chemical equipment exporter used ASTM A240 310s plate for high-temperature cracking furnace tubes. Due to its full ASTM A240 certification, the equipment was successfully exported to the EU. The equipment has operated at 850°C for two years without sulfidation corrosion or creep deformation, resulting in a 100% customer repurchase rate.
- An aviation parts supplier supplied ASTM A240 310s plate for a military project. Military testing confirmed that its 1200°C high-temperature performance and mechanical properties met ASTM A240 and military standards, successfully replacing imported material and reducing procurement costs by 40%.
