Description

Cold rolled steel, sometimes abbreviated to CRS, is well-known for being an extremely ductile material, and is ideal for applications where precision is necessary. It is used in many applications, like household appliances, furniture, lockers, and filing cabinets. In construction applications, CRS is commonly used for building garages, steel sheds, and other industrial buildings.
In simple terms, cold rolling is the process of strengthening steel by changing its shape without using heat. Cold rolling, unlike hot rolling such as with hot rolled steel, can only occur when a metal is below its re-crystallization temperature. Where hot rolling is performed using high temperatures, cold rolling is performed at room temperature. Instead of heat, mechanical stress is used to change the structure of metal. Strain hardening can then increase the metal's strength by up to 20%, and can also improve a metal's surface finish.

Application

stainless steel cold rolled coil is widely used in construction, surgery, kitchen essentials, etc. 304 stainless steel is suitable for the construction of external banisters and handrails, and it has good processing performance and weldability. 316 stainless steel is suitable for kitchen essentials such as equipment, cutlery and cookware, and it has good corrosion resistance and a wide range of shapes. 316L stainless steel is suitable for medical and surgical applications, which demand high levels of reliable performance.

Classification

There are many types of stainless steel coil price, which can be divided into several categories according to the organizational structure at room temperature:

1. Austenite type: such as 304, 321, 316, 310, etc.;

2. Martensite or ferrite type: such as 430, 420, 410, etc.;

Austenitic type is non-magnetic or weakly magnetic, and martensite or ferrite is magnetic.

The stainless steel usually used as decorative tube sheet is mostly austenitic stainless steel coil material. Generally speaking, it is non-magnetic or weak magnetic. However, due to chemical composition fluctuations or different processing conditions caused by smelting, magnetism may also appear, but this cannot be considered as Counterfeit or substandard.

As mentioned above, austenite is non-magnetic or weakly magnetic, while martensite or ferrite is magnetic. Due to component segregation or improper heat treatment during smelting, a small amount of martensite or ferrite in austenitic 304 stainless steel will be caused. Body tissue. In this way, 304 stainless steel will have weak magnetic properties.
