Standards for Monel K500 Tube

We make things that meet the standards set by ASTM B161, ASTM B725, and ASME SB-163. We follow EN 9120:2018 for aircraft delivery and ISO 9001 quality management, which makes sure that every batch is the same size and made of the same material.

What are the Features of Monel K500 Tube?

· High Strength: The age-hardening process makes the yield strength three times higher than in Monel 400.

· Better corrosion resistance: Works well in seawater, hydrofluoric acid, and sulfuric acid.

· Important for directed drills and MWD tools that are not magnetic.

· Resistance to Stress Corrosion and Cracking: Can handle chloride environments where stainless steels fail

· Low-Temperature Toughness: Keeps its flexibility at very low temperatures

Application

The Monel K500 Tube works well in the following situations:

· For oil and gas, we have downhole drilling collars, stabilizers, and MWD housings.

· In marine engineering, pump shafts, propeller sleeves, and valve stems are used in saltwater.

· Chemical Processing: Heat transfer tubes that work with acidic and basic substances

· Aerospace: parts that aren't magnetic and need to be strong for their weight

· Medical Devices: Surgical tools that need to be strong and biocompatible

Production and Processing Technology

We are in charge of every step at TSM Technology's 60,000㎡ production center, from vacuum induction melting to the final precise drawing. To get regular mechanical qualities, our age-hardening procedure starts with solution annealing at 980°C and then controls the cooling and aging at 600°C for 16 hours. Our automated bright annealing lines give the surfaces a better finish without rust, and our advanced CNC cutting and cold pilgering make sure that the tolerances are very tight (±0.05 mm on wall thickness).

Quality Inspection

According to ASTM B163 standards, every Monel K500 Tube goes through strict tests:

Chemical Analysis: ICP and OES checks for titanium and aluminum content

Mechanical tests: tensile, yield, elongation, and hardness (Rockwell C 25–35 is normal).

NDT: 100% ultrasonic (UT) and eddy-current (ET) checks for problems inside the product

For hydrostatic testing, the pressure integrity must be at 1.5 times the design pressure

Checking the dimensions: using a laser to measure the OD, WT, length, and straightness

Surface Inspection: A look at something under controlled lighting

Each package comes with full paperwork, such as MTC, ITP, and SGS reports.

FAQ

Q:What's the difference between Monel 400 and product?

A: Both have about the same level of resistance to rust, but Monel K500 has been age-hardened to have much higher tensile and yield strengths, which makes it perfect for building structures that need to be strong.

Q:Does Stress Corrosion Cracking (SCC) not happen in product?

A: Yes, it does not react with SCC in most fresh and industrial waters. In chloride environments, it works better than austenitic stainless steels.

Q: Is it possible to weld product?

A: Yes, cracking can be avoided in the heat-affected zone by using Monel Filler Metal 60 and being careful with heat. There is no need to heat up first.

Q: What kind of magnet is the tube?

A: No, product is still not magnetic. This is important for MWD and directional drilling tools because magnetic disturbance can change the accuracy of the survey.

Q: What is the highest temperature at which it can work?

A: We suggest constant use up to 480°C (900°F). Higher temps may weaken the material over time because they cause it to age too quickly.
