What is the Alloy K500 Round Bar?

Alloy K500 Round Bar is a precipitation hardened nickel-copper alloy. It has the great corrosion resistance of Monel 400 but with the extra strength of the age-hardening process.

The material is non-magnetic even at -101°C and may be used in magnetic survey equipment and cryogenic applications. The alloy maintains its structural integrity in harsh marine environments and high pressure systems.

Technical Specifications

Physical & Chemical Properties

Application

This alloy is resistant to saltwater and is used in components of marine engineering such as pump shafts, propeller blades and subsea equipment. It has a high strength-to-weight ratio and is used in turbine blades and aerospace fasteners.

Oil and gas extraction equipment may be safely used in sour gas settings . It is used for valve components and reactor internals in the chemical processing industry. Medical tools must be biocompatible and withstand sterilizing.

Production and Processing Technology

TSM Technology's 60,000㎡ facility combines vacuum induction melting, hot forging, precision rolling and CNC machining. We have 8 manufacturing lines which employ over 100 state-of-the-art machinery to guaranty precise tolerances. The age hardening process is conducted in computer controlled furnaces at 540-650°C for 8-16 hours to optimize the mechanical characteristics. Stress-relief annealing removes residual tensions, therefore reducing stress corrosion cracking.

Our quality team monitors processes in real-time throughout manufacture to make sure every Alloy K500 Round Bar fulfills specification criteria before to dispatch.

Quality Inspection

Comprehensive test processes are in place, according to nickel alloy bar requirements (ASTM B160, B166, B335).

• Chemical analysis: Composition and trace-element limitations confirmed by OES, XRF, ICP
• Mechanical Testing : The Performance is verified by Tensile, Hardness, Elongation and Reduction of Area tests.
• Non-Destructive Testing: Ultrasonic (UT), penetrant (PT) and magnetic particle (MT) examination detects internal and surface faults.
• Dimensional Inspection: Diameter, length and straightness measures are to specification.

FAQ

Q: How does product differ from Monel 400?

A: K500 undergoes precipitation hardening, delivering three times the yield strength and double the tensile strength of Monel 400 while maintaining similar corrosion resistance.

Q: Is product susceptible to stress corrosion cracking?

A: When age-hardened correctly, it demonstrates high resistance. Our products undergo stress-relief annealing to minimize this risk in demanding environments.

Q: Can this alloy function at sub-zero temperatures?

A: Yes. It remains non-magnetic down to -101°C, making it perfect for cryogenic applications and magnetic survey instruments.

Q: What machining considerations apply?

A: Its high work-hardening rate requires heavy-duty equipment, slow speeds, and tungsten carbide tools. We recommend machining in the annealed state when possible.

Q: Does your product meet NACE MR0175?

A: Absolutely. Our bars are processed to comply with NACE MR0175/ISO 15156 standards for H2S-containing oil and gas environments.
