Description
410 stainless steel is food grade, 410 stainless steel is not toxic, and it is not harmful to the human body when used as tableware. 410 stainless steel is a stainless steel grade produced in accordance with the American ASTM standard, equivalent to China's 1Cr13 stainless steel, S41000 (American AISI, ASTM). Carbon 0.15%, chromium 13%,410 stainless steel: has good corrosion resistance, machinability, general purpose blade class, valve class.
Choose stainless steel products, recommended to choose 304 steel. 304 steel (refers to stainless steel with chromium content of 18% and nickel content of 8%) is widely used in corrosion-resistant containers, tableware, furniture, railings, medical equipment and so on. The purchase of stainless steel products should be optimistic about the type of labeling.
There are often "13-0" (420 steel), "18-0" (430 steel), "18-8" (304 steel) on the stainless steel tableware, the number in front of the code indicates the chromium content, and the number behind represents the nickel content. Whether stainless steel utensils are safe is mainly a problem of heavy metal migration. In general, the 304 steel common on the market now is less chromium migration.
410 stainless steel Features:
1, high strength.
2. Excellent machinability.
3. Hardening occurs after heat treatment.
4. Magnetic.
5, not suitable for harsh corrosive environment.
6, scope of application: general blade, mechanical parts, class 1 tableware (spoon, fork, knife, etc.).
Application of galvanized steel coil
Galvanized steel coil can be divided into general use, roof use, building outer side plate use, structural use,tensile use and deep drawing use.
Main process flow of galvanized coil
The galvanizing production line is a complete set of equipment for hot-dip galvanizing a layer of zinc alloy coating on both sides of steel coils. The production line is composed of uncoiler, welding machine, storage machine, degreasing cleaning unit, continuous annealing furnace, zinc pot, air knife, finishing machine, tension straightener, oiler, shear, coiler and other equipment.
The coating used to produce color steel coil basically consists of four parts, namely resin, pigment, solvent and auxiliary agent. Among them, the solvent is volatile, and its three parts are basically non-volatile.
1.Hot-dip galvanized color coated steel sheet(prepainted galvanized steel sheet)The product obtained by coating an organic coating on a hot-dip galvanized steel sheet is a hot-dip galvanized color-coated plate. In addition to the protective effect of zinc, the hot-dip galvanized color-coated sheet also protects against rust and has a longer service life than hot-dip galvanized sheet;
2.Hot-dip aluminum-zinc color coated sheet(prepainted galvalume steel sheet)Hot-dip aluminum-zinc steel sheets can also be used as color-coated substrates (55% AI-Zn and 5% AI-Zn);
3.Electroplated zinc color coated sheet The electro-galvanized sheet is used as the substrate, and the product obtained by baking with the organic coating is an electrogalvanized color-coated plate. It has a beautiful appearance and excellent processing properties, and therefore can be mainly used for home appliances, audio, steel furniture, interior decoration, and the like.
The zinc layer has uniform thickness and strong adhesion. No peeling and good corrosion resistance.The Surface is very smooth and clean,zinc flower is symmetrical,beautiful.
Galvanized Coil With the cold rolled steel of different strength and thickness as substrate, it is produced through applying the zinc coated on both faces by hot dip process.
Large inventory All products are packed and warehousedafter passing the inspection, and deliveredin one order. So as to ensure that the customer's products can be delivered in the shortest time. You don't have to worry about the quality and transportation of the goods at all.
