1. What is ASME SA240 Gr 405 (S40500)?

ASME SA240 Gr 405, also known as UNS S40500, is a ferritic stainless steel alloy with 11.5-14.5% chromium and aluminum additions (0.1-0.3%) for enhanced oxidation resistance. It is designed for moderate corrosion resistance and excellent heat resistance up to 815°C (1500°F), with improved weldability due to its low carbon content and aluminum stabilization, which prevents hardening during cooling after welding.

ASME SA240 Gr 405 materialis ideal for applications requiring cost-effective performance in high-temperature environments with moderate corrosion exposure, such as heat exchanger components, furnace parts, and automotive exhaust systems. Compared to ASME SA240 Gr 409, ASME SA240 Gr 405 offers better weldability and resistance to scaling at elevated temperatures.

Gangsteel’s ASME SA240 Gr 405 stainless steel plate is engineered for industries seeking affordable, heat-resistant solutions, providing a practical alternative to grades like ASME SA240 Gr 430 or ASME SA240 Gr 410.
