Color steel and stainless steel distinction

Stainless steel color sheet

1. Different definitions
Color steel: color steel plate, refers to the color coated steel plate, color coated steel plate is a kind of steel plate with organic coating.
Color steel plate is divided into veneer, color steel composite plate, floor plate.
Stainless Steel: Stainless Steel (Stainless Steel) is short for acid-proof Stainless Steel, resistant to weak corrosive medium such as air, steam, water, or with a Stainless Steel grade is called Stainless Steel;
And will be resistant to chemical corrosion medium (acid, alkali, salt and other chemical etching) corrosion steel is known as acid steel.
2. Different characteristics
Color steel: light weight: 10-14 kg/m2, equivalent to 1/30 of the brick wall.
Thermal insulation: thermal conductivity of core material: <=0.041w/mk.
High strength: it can be used as load-bearing plate of ceiling envelope structure, bending and compression resistance;
General houses do not use beams and columns.
Bright color: no surface decoration, color galvanized steel anticorrosion coating period in 10-15 years.
Flexible and fast installation: construction period can be shortened more than 40%.
Oxygen index :( OI)32.0(provincial fire product quality inspection station).
Stainless steel: weldability, product use of different welding performance requirements are also different.
A kind of tableware does not do requirement to welding property commonly, include partial boiler kind enterprise even.
But the vast majority of products require good welding performance of raw materials, such as second-class tableware, thermos cups, steel pipes, water heaters, water dispensers, etc.
Corrosion resistance, the vast majority of stainless steel products require good corrosion resistance, such as one, two kinds of tableware, kitchen utensils, water heaters, water dispensers, some foreign businessmen also do corrosion resistance of the product test: with NACL solution to boil, after a period of time to pour away the solution,
Wash, dry and weigh the weight loss to determine the degree of corrosion (note: when polishing the product, due to the presence of Fe in emery cloth or sandpaper, the surface will appear rust during testing)
Polishing performance, today’s society stainless steel products in the production of this process is generally through polishing, only a few products such as water heater, drinking machine tank do not need polishing.
Therefore, this requires the raw material polishing performance is very good.
Heat resistance, heat resistance refers to the high temperature stainless steel can still maintain its excellent physical and mechanical properties.

3. Different USES
Color steel: the color steel plate for construction is generally hot-dip galvanized steel plate and hot-dip aluminum-zinc steel plate as the substrate, mainly processed into corrugated plate or polyurethane composite sandwich plate, used for the construction of steel structure workshop, airport, warehouse, refrigerated warehouse and other industrial and commercial buildings roof, wall, door.
The color board of home appliance is general with galvanization of electricity and cold board are base board, use at producing freezer and large air conditioning system, freezer, bread machine, furniture.
The transportation industry is generally galvanized and cold plate as the substrate, mainly used for oil sump, automotive interior decoration.
