A179 is a steel grade produced according to American ASTM standards, which belongs to American standard. A53 Carbon steel round bar is applicable to cold drawn high-quality low-carbon seamless steel pipe for heat exchanger and condenser Round steel has relatively high strength, high hardenability and very good toughness, so its pressure bearing capacity is also guaranteed. Even if it is used at high temperature, the creep strength is high and the durability is also guaranteed.

Incoloy 800H coil is made of an austenitic heat-resistant alloy widely used in high-temperature environments. It has attracted much attention because of its good high-temperature strength, oxidation resistance and corrosion resistance. Incoloy 800H is widely used in equipment manufacturing in various high-temperature environme
