Corrosion Resistant Tin Plate Steel Coils For Food Cans

Corrosion Resistant Tin Plate Steel Coils For Food Cans

Tin plate offers the strength of steel combined with the noncorrosive and nontoxic properties of tin. It is available in a wide range of gauges, coating weights and tempers.

Electrolytic tinplate is made from strip steel that is cleaned in a pickling solution and then coated with tin by electrolytic deposition. This tin layer is melted and fused, leaving a beautiful metallic luster.

Corrosion Resistance

Corrosion resistance is the ability to resist corrosion. It is important for industrial metals, such as tinplate steel, because it is used for packaging and manufacturing food. This material is also useful in the automotive, building, and appliance industries, where it provides strength and formability. It is also durable and easy to weld. Moreover, it has good ductility and a beautiful appearance. It is also hygienic, nontoxic and recyclable, making it an excellent material for food cans.

Electrolytic tin plate is made from cold-rolled low-carbon thin steel strips tinplate steel coils for food cans that are coated with commercial pure tin on both sides. The tin is applied using an electrolytic process that deposits the coating in a series of tanks. The tin coating thickness is typically between 0.4 and 2.1 mm. The tin coating protects the underlying steel and enhances its formability, weldability, paintability, printability, and colorability.

The tinplate steel is further processed to improve critical characteristics, such as formability, weldability, and strength, before being shipped to the canmakers. This process includes cold rolling to a gauge that is lighter than the initial black plate coil, and then tempering or forming into tinplate or TFS. The tinplate can be further coated in zinc and aluminum to make it galvanized. The tinplate cans are then sold for use in various industries. They offer superb corrosion resistance, are light and strong, and can be easily transported and stored.

Weldability

Besides its strong structure, tin plate has good weldability and solderability. It is also non-toxic and provides excellent barrier properties to protect food products from impurities, bacteria, moisture, light and odours. This enables the contents to be stored and preserved for a longer time. The tin coating also helps preserve nutritional values by keeping the product’s taste and colour. It also helps to reduce oxidation of juices and other soft drinks, and it can be easily recycled.

Tinplate steel coils are a type of cold-rolled low-carbon iron sheet coated with commercial pure tin on both sides. It is available in a wide range of tempers, tin coating weights, and surface finishes. It is a good choice for making food cans, because it is easy to work with and has good corrosion resistance. MR grade is a commonly used tinplate for general line cans. Other grades, such as GL, can be used for more specific applications.

Electrolytic tinplate is a cold-rolled low-carbon steel of 0.0149 inch thickness or lighter on which tin has been electrodeposited. It is a low-cost material that is highly recyclable. It can be welded by hand or by machine and offers good weldability, solderability and corrosion resistance. It is widely used in the production of tin cans for beverages, food and chemical products. It is also used in the manufacture of metal closures for containers and bottles.

Printability

Tin plate has a beautiful metallic luster and excellent properties in corrosion resistance, formability and weldability. It can be printed in a variety of different patterns, making it a Annealed Steel Strip popular choice for food cans and industrial parts. It is also odorless, non-toxic, and easy to shape and process into a finished product.

During production, the tinplate is passed through a series of mechanical tests. These include the tensile test and Rockwell hardness test. The tensile test measures the strength of the tinplate, while the Rockwell hardness test is used to gauge its hardness.

Once the tinplate has undergone the mechanical tests, it undergoes a final anneal. This helps to reduce the amount of tin that is lost during the manufacturing process. It is then punched into a coil and is ready for use in the production of food cans.

The tinplate is either equally or differentially coated. Equally coated means both sides of the steel have an equal layer of tin, while differentially coated means one side has a higher layer of tin than the other. It is also passivated, which prevents the tin from reacting with water or foods.

Our tinplate coils are available in various sizes, and can be silk-screened or printed. They are also packed in standard export packing or according to customer’s requests.

Appearance

Tinplate has the strength and formability of steel and the nontoxic and noncorrosive properties of tin. It is odorless and tasteless, which makes it ideal for food containers. It is also paintable, allowing manufacturers to add logos and trademarks to their products. Additionally, it is easy to solder, which helps to increase production speed and reduce labor costs.

The tinplate steel sheet goes through a number of processes before it is made into coils. First, it undergoes an electrolytic leaning process, which removes impurities from the steel. The clean substrate then goes through temper rolling, which is a heat treatment that softens the metal. This process produces a thinner and lighter coil.

After the tinplate is rolled, it undergoes annealing. This process aims to prevent internal stresses that may cause the coils to become brittle. It can be done in two ways: continuous annealing and batch annealing. Continuous annealing involves passing the tinplate continuously through heaters, while batch annealing involves baking it individually.

The tinplate is then flow melted in an electrolytic tank, which bonds the tin to the steel surface. The molten tin forms an oxide film that protects the steel and gives it a shiny appearance. The tinplate can then be welded to produce a smooth and even surface. The tin coating is usually painted with a bright finish to make it look attractive, and the welded joints are called lap welds.
