HASTELLOY FASTENERS : PRODUCT

Hastelloy is a super alloy that contains nickel, molybdenum, chromium and an addition of tungsten. Hastelloy fasteners have excellent corrosion resistance in a number of severe environments. Hastelloy fasteners contain a low carbon content which minimizes gain-boundary carbide perception. It also has an outstanding resistance to strong solutions of oxidizing salts such as ferric and cupric chlorides. There are a very limited number of fasteners that have resistance the corrosive effects of wet chlorine gas, hypochlorite, and chlorine dioxide Hastelloy fasteners being one of them. Because of its ability to withstand oxidizing in reducing and neutral atmospheres, Hastelloy fasteners are very useful in aircraft, automobiles and chemical processes. Hastelloy fasteners also have good resistance to localized corrosion such as pitting and stress-corrosion cracking.

PRODUCTION OF HASTELLOY FASTENERS

We have a state of the art mill facilities access which runs at a full capacity due to export order overload. We have 3 heavy punch machines for shaping the bar. We also have threads machines to make NPT, BSPT & BSPP threads to the forging. Added to that we have in house testing facilities like spectro machine, PMI Machine, Mechanical test, Hardness Test, Ultrasonic Testing, Hydrostatic Testing, Pressure testing, and manual inspection of gauge.

The production process can be divided separately for different type of Hastelloy Fasteners Manufacturers:

Nuts:

Nuts are manufactured from hex bars. The hex bars are subject to CNC Machining that ensures the nuts are compatible with the bolts of the given size.

Bolts:

The bolts are manufactured from round bars either original bright or forged. The bolts are then threaded as per size. The head is either round, hex or of different shape as required in order specification.

Washers:

Washers are manufactured from plates. The size of hold depends on the bolt and nut along with which it has to be used.

Our intelligent procurement module places a lot of emphasis on selection of raw material. As much as possible, we try to procure Japanese and European origin raw material domestically or from the international markets. Secondary preference is given to Indian and Chinese origin raw material from good quality mills.
