Inconel 600 Fasteners 

Introduction to Inconel 600 Fasteners

Kalpataru Piping is a well known supplier/ exporter of Inconel 600 Fasteners in India, the production of Inconel 600 fasteners which is highly performance oriented and has the ability to endure extreme heat, pressure and even corrosive environment. Designed as per ASTM B166 / ASME SB166 for Inconel 600 (UNS N06600 / Werkstoff Nr. These clamps give an excellent oxidation resistance and mechanical strength of 2.4816). The low coefficient of friction decreases sticking or galling in a wet or salty environment.

Frequently Asked Questions About Inconel 600 Fasteners

How does the Inconel 600 nuts differ significantly with Inconel 625 nuts?

Nuts made of Inconel 600 (UNS N06600) have better oxidation and high temperature stability. Nuts made of Inconel 625 (UNS N06625) have better tensile strength and high pitting/crevice corrosion resistance because of molybdenum and niobium. Select on the basis of temperature range and corrosion environment.

Inconel 600 fasteners have a general use?

Applications A: Inconel 600 fasteners are also common in nuclear reactors, heat treating equipment, chemical processing, marine, aerospace and oil and gas pipelines where high heat and corrosion resistance are needed.

What are the types of thread used in Inconel 600 fasteners?

Inconel 600 fasteners are provided by us in UNC, UNF, BSW, BSF, ISO Metric and 8UN thread forms in accordance with ASME B1.1 and B1.13M specifications.

What is the reason why Inconel 600 fasteners are chosen when it comes to nuclear reactor?

Inconel 600 is resistant to chloride-ion stress corrosion cracking (SCC) and has a mechanical property to 1175 o C. It is excellent in thermal expansion coefficient and nickel-chromium composition, which makes it stable, and therefore, it is excellent in nuclear pressure vessel and steam generator.

How much is the price of the Inconel 600 fasteners in India per kg?

The prices depend on the size and thread, coating, and quantity. Prices vary between 420 and 1450 or more per unit of bolts (M6 to M12). Get in touch with Kalpataru Piping at exporting piping kalpatarupiping.com with specific quote depending on your needs.

How and what are the terms of payment and shipment?

We do accept LC (Letter of Credit), TT (Telegraphic Transfer) and Cheque. The fasteners are shipped at the JNPT Mumbai / Kalamboli, Maharashtra, India.
