What is the difference between "sheet metal" and "sheet metal"?

Release date:2017-11-29 Author:Source Network Click:

Sheet metal is also sometimes used as a pull-out metal. The word comes from the English platemetal. It is generally the case that some sheet metal is plastically deformed by hand or die stamping to form the desired shape and size and can be further processed by welding or a small amount of machining Forming more complex parts, such as chimneys commonly used in homes, tin stoves, and car enclosures are sheet metal parts.

Sheet metal, Sheet Metal in English), sheet metal has yet to have a more complete definition. According to a definition of a foreign professional journal, it can be defined as: Sheet metal is a sheet metal (usually 6mm below) a comprehensive cold working process, including cutting, punching / cutting / composite, folding, welding, riveting, Stitching, forming (such as car body) and so on. The salient feature is the same part thickness. Metal Sheet; Sheet Metal in English is a technical means of automobile repair. In this respect, automobile sheet metal equals automobile sheet metal repair, which refers to the repair of the automobile body after the automobile collision, that is, in addition to the automobile body Anticorrosive and decorative paints work all the rest of the job. Such as automobile body damage analysis, automobile body measurement, automobile body sheet metal shaping, stretching correction, to stress welding, as well as automobile body accessories assembly, adjustment and so on.


The main purpose of sheet metal

Suitable for stamping process sheet metal material is very large, widely used in electrical and electronic industry sheet metal materials include:

⒈ ordinary cold-rolled plate SPCC SPCC refers to the continuous rolling of the ingot through the cold rolling mill into the required thickness of the coil material or sheet. SPCC surface without any protection, exposed to the air can easily be oxidized, especially in humid environment, accelerated oxidation, the emergence of dark red rust, when used to paint the surface, electroplating or other protection.

⒉ galvanized steel SECC SECC substrate for the general cold-rolled coil in the continuous galvanized line after degreasing, pickling, electroplating and a variety of post-processing process, which became electrogalvanized products. SECC not only has the general cold-rolled steel mechanical properties and approximate processibility, but also has excellent corrosion resistance and decorative appearance. In the electronics, home appliances and furniture market has great competition and substitutability. For example, the computer chassis is commonly used SECC.

⒊ Hot dip galvanized steel plate SGCC hot dip galvanized steel coil refers to the hot-rolled pickling or cold-rolled semi-finished products, after cleaning, annealing, immersed in a molten zinc bath temperature of about 460 ° C, and the steel plate Zinc layer, then quenched and leveled and chemical treatment made. The SGCC material is harder than the SECC material with poor ductility (avoiding deep draw design), a thicker zinc coating and poor weldability.

⒋ stainless steel SUS301 Cr (chromium) content lower than SUS304, poor corrosion resistance, but after cold work can get good tensile strength and hardness, good elasticity, and more for the leaf spring and anti-EMI.

⒌ Stainless Steel SUS304 One of the most widely used stainless steels, Ni-containing steel is more corrosion-resistant and heat-resistant than Cr-containing steels. It has very good mechanical properties, no heat treatment and hardening, no elasticity .
