Super 00Cr Stainless Steel Sucker Rod
The characteristics of super anti-corrosion 00Cr material are concentrated in
high-strength, corrosion-resistant, fatigue-resistant, and wear-resistant. The mechanical
properties exceed some of the world's steel superpowers in the United States and Japan.
The comprehensive performance is far superior to that of Japan 13Cr.

High Strength
By increasing the content of other alloy elements, adding rare earth elements, using
controlled rolling and cooling technology, the steel's molecular structure is improved and
high-grade mechanical properties are achieved. Through the heat treatment process to
adjust the change of six kind metallurgical structures, it will achieve different levels of
material mechanical properties, in order to meet the safety requirement of materials in
different areas and working conditions. Tensile strength can be up to 1300MPa, and yield
strength can be up to 1050MPa and impact energy up to 80J at -40 °C.
Anti-Corrosion
Under the same conditions, the diffusion rate of Cr atoms in ultra-00Cr materials is several
decades faster than ordinary materials, which can effectively prevent intergranular
corrosion and point corrosion. The content of Cr in the grain and the grain boundary is
more easily balanced, with stronger corrosion resistance preventing grain boundary
corrosion and. When corroded by the medium, a Cr-rich passivation film is formed on the
surface to isolate the matrix metal from the corrosive medium. When the temperature of
the corrosive medium rises to 120°C-180°C, the surface is re-passivated and Cr-rich
again. The damaged passivation film begins to be repaired. The unstable components in
the passive film are washed away by the fluid and passivated after repair. The stability of
the film composition is better than that of a passivation film formed at a static state at this
temperature, and the anticorrosion performance is superior.
According to NACE TM 0284-2016 Standard A Method test result, under saturated H2S
2680 mg/L and 96 hours, no Hydrogen bubbling is detected on the surface.
Wear Resistance
The sucker rod products manufactured by Super 00Cr material have reasonable design of
rare earth alloy components, and adopt scientific metal tribology design and heat
treatment processing technology to ensure strong corrosion resistance and wear
resistance in various working environments.
High Density
Super 00Cr material uses special production technology to improve the microstructure
density of alloy steel, in order to obtain fine steel of excellent sorbite metallographic
structure. Sorbite is a small pearlite, also called "Nano-Steel", with good mechanical
properties, low residual stress, and a good match between strength and toughness. Fine
crystals and low residual stress both have good properties for resisting grain boundary
corrosion, electrochemical corrosion, pitting corrosion, and stress corrosion.
