Kuama Steel's stainless steel coil inventory includes stainless steel coil products of various specifications
Widely used in all walks of life, it is an important material for modern industry.
Stainless steel coils can be divided into cold rolled stainless steel coils and hot rolled stainless steel coils according to different production processes.
According to the material can be divided into austenite, martensite, ferritic and duplex.
Commonly used stainless steel coil grade is usually expressed in numerical symbols.
There are 200 series, 300 series, 400 series and compound series.
304, 304L, 316 and 316L stainless steel coils are the most popular and economical grades of stainless steel.
Stainless steel 304/304L coils and stainless steel 316/316L coils and duplex stainless steel coils offer good corrosion resistance to many chemical environments as well as marine and industrial exposures.

Stainless steel coils are an excellent choice for a variety of applications, including heating and cooling systems, food processing facilities and even your home.
They are highly durable and can withstand high temperatures. In addition, they offer many advantages over other types of metal coils:
Stainless steel coils have a much longer lifespan than copper or aluminum. This means that you will get more use out of these coils before they need to be replaced. They also require less maintenance so you won’t have to worry about repairing them as often as other types of coils.
Stainless steel coils can withstand temperatures up to 2,000 degrees Fahrenheit without melting or warping. This makes them ideal for industrial processes that involve extreme heat such as chemical manufacturing and oil refineries. They can also be used in residential applications such as cooking stoves and fireplaces where there is a risk of fire starting due to exposed flames from burning wood or coal fires.
Stainless steel has excellent thermal conductivity properties that allow it to transfer heat quickly throughout its entire length — unlike other metals that may only conduct heat through their outer layers while their inner layers remain cool.
Rolled edge is the appearance of untrimmed edges after hot or cold rolling and annealing/pickling processes. It usually leaves irregular pinhole lines on the 10mm to 15mm side of the edge.
Slitting/slitting edge means we will trim the irregular pinhole lines on the slitter.
7219110000 – hot rolled stainless steel coil with thickness > 10mm;
7219120000 – 4.75mm ≤ 10mm thick hot rolled stainless steel coil;
7219131200 – hot rolled stainless steel coil with 3mm ≤ thickness ＜ 4.75mm without pickling;
7219131900 – other hot rolled stainless steel coils with 3mm ≤ thickness ＜ 4.75mm without pickling.
