Detailed Information:

The RatnaExports.com company manufactures and provides stainless steel washers in grades, sizes, and dimensions. We provide plain washers, star washers, spring washers, tooth washers, taper washers, tab washers, and so on. Moreover, it is available in custom-made specifications so that clients can satisfy their application needs.

Stainless steel 304 washers are usually used in various industries, including paper, food, refrigeration, and chemicals. These washers are highly used due to their high and low-temperature resistance. As well as having suitable welding and forming properties, stainless steel 304/304l washers also have excellent deep drawing properties.

As a result of the chromium content in stainless steel 304L washers, they are highly resistant to oxidation. They deliver excellent formability and ease of fabrication. 304-grade washers are designed to withstand extreme stress loads. The hardened temper is easy to achieve with grade 304L.

There are five mechanical and physical properties of stainless steel washers: density, melting point, tensile strength, yield strength, and elongation.

A stainless steel 304/304L washer is used in a wide range of industries, including furnaces (recuperators, fans, burners, doors, pipes), food processing industries, petrochemical and petroleum refineries for flares, recuperators, tube hangers, power generation for tube hangers, coal burners, cement plants – burners, burner shields, wind boxes feeding, and thermal process plants for annealing covers and boxes.

There are many advantages to stainless steel, including excellent formability, good strength-to-weight ratio, ease of fabrication and cleaning, excellent toughness at cryogenic temperatures, and corrosion resistance.

A low content of grade 304l is ideal when severe oxidizing conditions are present due to its excellent resistance to intergranular oxidation.

In addition to mechanical testing and chemical analysis, corrosion tests, die penetration tests, chloride contamination tests, microstructure tests, positive material identification tests, hydro tests, surface roughness tests, etc., are included in the documentation. The package includes various documents, including fumigation certificates, raw material test reports, quality assurance plans, and heat treatment charts.
