The 439 steel grade is based on the common ferritic stainless steel material 1Cr17 (430) to reduce the C content,
and at the same time adds Ti and other stabilizing elements, so that the intergranular corrosion resistance,
formability and weldability of the steel are improved. 439 stainless steel seamless pipes are mainly used in stress
corrosion-resistant environments, such as hydrogen sulfide, chloride ion environment for petroleum refining heat
exchanger pipes, oil production or oil pipelines; high-pressure heater pipes for various power plants, nuclear power
steam-water separation reheaters Tubes, waste heat boiler tubes of gas-fired power plants; waste heat utilization
air heat exchanger tubes of steel mills with high temperature sulfur corrosion (below 927 degrees Celsius).
