STAINLESS STEEL FASTENERS : PRODUCT

Stainless steel fasteners are known for their exceptional corrosion resistance and heat resistant properties. Stainless steel fasteners contain a minimum of 10.5% chromium which is fundamental in the resistance to corrosion. The chromium levels can be increased to help achieve a better resistance to corrosion. Other components like nickel, molybdenum and nitrogen can be added to increase corrosion resistance, resistance to pitting corrosion and mechanical strength respectively. Stainless steel fasteners are preferred not only for its high corrosion resistance levels but also for its other renowned properties like high-temperature strength, toughness in a number of environments and ductility. Stainless steel fasteners are high strength fasteners that are applicable in industries that require high-pressure like Hydrocarbon Industries & Refineries and Oil & Gas Exploration & Drilling.

PRODUCTION OF STAINLESS STEEL 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 Stainless Steel 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.

We are also members of various renowned agencies and Chambers of Commerce including MASSMA, EEPC, FICCI, FIEO, Indian Merchants Chamber etc. We provide a 1 year product replacement warranty for all Stainless steel fasteners exported from our company. We guarantee the quality because 100% Stainless steel fasteners manufactured are checked in house for defects in quality and workmanship. Our quality program is a 3 layered independent department check for various factors including Dimensional Check, Visual Inspection, and Finishing, Burr level, Leakage Test, Pressure Rating test, Chemical inspection and Mechanical properties verification. We are running at full capacities and sometimes outsource our job due to increased work load.
