Stainless
Steel Flanges are frequently produced from common
stainless steel grades like stainless steel 304 and 316. These alloys are
made up of varying amounts of iron and chromium metal, as well as other
micro components. Some of the desirable features and attributes of stainless
steel alloy are as follows:
• excellent corrosion resistance
• exceptional durability
• high tensile strength
• can be utilized in high temperatures
• long-lasting
• are recyclable and environmentally friendly

Stainless steel flanges
are classified into four categories depending on their chemical structure. These four
categories are ferritic, austenitic, martensitic, and duplex. Each of the categories has
unique characteristics that make them valuable for specific applications and industries.
The SS alloys are used in a variety of fields and sectors. Its usage can span from
industrial to consumer durables.
Stainless Steel flanges are of various grades such as 200 series austenitic alloys, 300
series austenitic alloys, 500 series, 600 series martensitic age-hardened alloys, 400
series ferritic and martensitic alloys, and others. Austenitic stainless steel is the
most popular and widely used family of stainless steel. Common commercial stainless
steel grades include 304, 316, 310, and 321. While annealed with a solution, austenitic
stainless steel is non-magnetic, and certain cold wrought grades are magnetic. Thermal
hardening will not work on these steels. They do, however, have good corrosion and creep
resistance while being suitable for welding.
