/ 1.7362 Strip coils - It is a martensitic heat-resistant steel with low heat strength. Below 550 ° C, it has good heat resistance and corrosion resistance in a sulfur-containing oxidizing atmosphere and a hot petroleum medium. The steel can
Poor weldability, slow cooling after welding, and tempering at 850 °C to improve weld performance. This steel starts to violently oxidize above 650 °C, but still has some thermal strength.
