Stainless steel coil

AISI 304 stainless steel coil is one of the most common stainless steel materials. It is used in industrial and commercial fields. The coil is known for corrosion resistance, strength, and flexibility. It has good strength and good formability. It is chosen for construction, food processing, chemical equipment, and automotive manufacturing.

Chemical Composition (Typical, % by weight)

Mechanical Properties

FAQs

Q1: What is the difference between 304 and 316 stainless steel coil?

304 is for general use. 316 has molybdenum, so it resists chloride corrosion better.

Q2: Can AISI 304 stainless steel coil be polished?

Yes. It can be brushed, satin, or mirror-polished.

Q3: Which industries use 304 stainless steel coil the most?

It is used in construction, food processing, chemical equipment, automotive, and household goods.
