Hastelloy Washers
Hastelloy Washers Description
Material selection and processing
C276 is one of the most widely used Hastelloy alloys. We mainly use powder metallurgy to make it.
High temperature fusion of various elements-forging process-repeated rolling into plates-cutting and drilling process-stamping forming-solution heat treatment-polished surface treatment-comprehensive quality inspection.
Characteristics
1. Super corrosion resistance
- Resistance to a variety of acids: excellent resistance to oxidizing acids and reducing acids.
- Resistance to pitting and crevice corrosion: It has strong corrosion resistance to various salt solutions, such as chloride and sulfate.
- High temperature corrosion resistance: it can still maintain good corrosion resistance under high temperature conditions and will not be deformed.
2. Good thermal stability
- It can maintain its mechanical properties at higher temperatures and be used for a long time.
- Strong thermal fatigue resistance: good toughness, not easy to crack or deform, long service life.
Application
C276 Washer mainly plays the role of sealing and shock absorption, which can effectively prevent medium leakage, withstand the erosion of pressure and corrosive media, and improve the reliability and service life of equipment.
Hastelloy Alloy C276 Flat Washers are widely used in chemical, petrochemical, flue gas desulfurization, pulp and papermaking and other fields. They are often used to manufacture chemical pipelines, valves, seawater treatment systems, oil refining equipment, pharmaceutical equipment, sewage treatment equipment, nuclear power plants and other equipment that need to operate in a high-intensity corrosive environment.
The main functions of Alloy C276 Fasteners are:
- Connection and fastening
In various mechanical equipment and structural parts, through bolts, nuts, screws and other C276 fasteners, different parts can be connected to form a complete component to prevent the relative displacement or loosening of parts during the working process.
- Seal and leak proof
In pressure vessels, reactors and other equipment, to ensure excellent sealing, to prevent internal high temperature, high pressure, corrosive media leakage.
- Ensure long-lasting safe operation
It can resist the erosion of various media, maintain good mechanical properties and connection fastening performance, and ensure long-term stable operation of equipment in harsh environments.
- Easy to install and disassemble
When the equipment is repaired, maintained or replaced, the relevant parts can be easily separated without causing too much damage, reducing the maintenance cost and downtime of the equipment.
