Delivery status of Hastelloy C276 steel pipe
Hot-rolled state: After high-temperature rolling, the inner and outer surfaces of the material maintain good smoothness.
Fine rolling state: Cold processing is performed to improve the dimensional accuracy and surface quality of the material.
Annealed state: After heat treatment, the material is more stable and the corrosion resistance is enhanced.
Pickling state: The surface iron oxide is removed by pickling to ensure the surface cleanness of the product.
