ASTM B366 Incoloy 800 alloy is an iron, nickel, and chromium alloy that offers excellent resistance to carburizing and oxidation at high temperatures. Incoloy grades differ only in the level of content and the addition of titanium and aluminum. Incoloy 800 was the first alloy in the series, and subsequent modifications were made to optimize stress-to-rupture attributes by controlling carbon and grain size.
This alloy has been further modified to combine with aluminum and titanium levels that ensure optimum higher temperature properties. It is dual-certified and combines properties of both forms.
Table Of Content
ASTM B366 Incoloy 800 Buttweld Pipe Fittings are designed for high-temperature structural applications. The presence of nickel content makes them highly resistant to chloride stress corrosion cracking and embrittlement from precipitation of the sigma phase. Their general corrosion resistance property is excellent.
ASTM B366 Incoloy 800 alloy features and properties:-
In addition, these fittings offer superior creep and stress rupture properties in solution-annealed conditions. They can be used in applications with temperatures up to 1100 deg F, where other standard fittings may become distorted. The chemical structure allows the fittings to exhibit excellent resistance to oxidation, nitriding, and carburization. They will not become embrittled even after long exposure to high temperatures.
At Piyush Steel, we adhere to industrial quality norms at all levels of our business. We are committed to providing our customers with uncompromising quality and services. We achieve the highest quality standards through a team approach where all our members work within the industrial standards and design codes. Our quality control personnel are highly trained and knowledgeable in industry standards, and we use the latest inspection tools and machines to meet all customer requirements.
Quality policy:-
Our quality personnel ensures high quality, tolerance, and traceable products. We clear various material and destructive tests, including hardness, tensile, compression, leakage, pressure, and mechanical tests, among others. Material tests include positive material tests, radiographic tests, micro and macro tests, intergranular corrosion tests, flaring tests, flattening tests, ultrasonic tests, pitting corrosion tests, and more.
We pack our ASTM B366 Incoloy 800 Buttweld Pipe Fittings in industrial standard packing to eliminate the chances of damage during export. They are packed in wooden cases, plywood cartons, woven bags, and boxes and individually wrapped in a thin plastic film to protect against contamination and rusting during transport.
The destructive tests are hardness test, tensile test, compression test, leakage test, pressure test, mechanical test and more. Material tests are the positive material test, radiographic test, micro, and macro test, intergranular corrosion test, flaring test, flattening test, ultrasonic test, pitting corrosion test, etc.
Packaging:-
ASTM B366 Incoloy 800 Buttweld Pipe Fittings are packed in the industrial standard packing to eliminate the chances of damages while exporting. These are packed in mainly wooden cases, plywood cartons, woven bags, and boxes. It is also individually wrapped in the thin film of plastic that adds protection from contamination and rusting while exporting.
