SEW680 10Ni14 Low Temperature Steel Pipe
10Ni14 steel pipe is a kind of low temperature steel. It has a high concentration of alloy elements and is mainly corrosion-resistant steel, heat-resistant steel, wear-resistant steel and other special steels with physical and chemical properties. Alloy structural steel has better mechanical properties than carbon structural steel, especially excellent heat treatment properties.
The alloy is typically produced by EAF /VD /LF and can be electroslag refined (ESR) if required for special applications.
Depending on the customer's requirements, GNEE will perform different levels of ultrasonic inspection on bars and forgings (if applicable).
Rod stock is usually supplied bright in the annealed condition.
Final heat treatment-heat treatment/QT.
