0.6mm 316L 430 stainless steel coil Cold Rolled For Industry
Stainless steel basics
To understand why stainless steel is rust-resistant, and how this resistance breaks down, it is helpful to understand how these alloys are different than other steels.Stainless contains a minimum of 10.5% chromium. This chromium reacts quickly with surrounding oxygen to form a thin oxide layer on the steel's surface. Unlike iron oxide, which often is in the form of flaky and corrosive rust, the chromium oxide clings to the steel. It therefore acts as a protective barrier. The chromium oxide is known as a passive film which seals the iron in the alloy away from the air and water in the environment. This film gives stainless its rust-resistance.Stainless steel is low maintenance, and its resistance to oxidation and staining makes it an ideal material for many applications.There are four main types of stainless steels: austenitic, ferritic, martensitic, and duplex. Austenitic stainless steelis dominant in industry and comprises over 70% of total stainless steel production. Its properties include a maximum of 0.15% carbon and a minimum of 16% chromium, yielding very strong protection against rust. Ferritic stainless steel has reduced corrosion resistance compared to austenitic grades, but fares better than martensitic stainless steel. Duplex stainless steels have high resistance to localized corrosion particularly pitting, crevice corrosion, and stress corrosion cracking.

Difference between cold rolling and hot rolling
The stainless steel coil has two opposing technologies. When it exceeds the phase transition temperature of 912 degrees Celsius, it is hot processing, and when the temperature is lower than this temperature, it is cold processing.
Cold-rolled Stainless steel plate:Cold-rolled Stainless steel plate is a stainless steel plate produced by cold-rolling process. Used to make corrosion-resistant parts, pipelines, containers, medical equipment, marine equipment, etc. Divided into austenitic steel, austenitic-ferritic steel, ferritic steel, martensitic steel.
Hot rolled Stainless steel plate :After the straight hair coil is processed by a finishing line such as head cutting, tail cutting, edge trimming, and multi-pass straightening and leveling, then it is cut or re-coiled to become; hot-rolled stainless steel plate. It has a smooth surface, high plasticity, toughness and mechanical strength, and is resistant to corrosion by acids, alkaline gases, solutions and other media. It is an alloy steel that is not easy to rust.
Applications of Stainless Steel
Due to the many great features of stainless steel, it is widely
used in many industries. It includes constructions, home
appliances, automobiles, kitchen accessories, mechanical structure,
decoration engineering, chemical industry, etc.
