The Difference Between Cold Rolled And Hot Rolled 304 Stainless Steel Plate

Classification of 304 stainless steel plate:
304 stainless steel plate is a relatively common material in real life. Whether it is building materials, industry, food and other industries, 304 stainless steel materials are closely related. 304 stainless steel plate has a more specific division, that is, it is divided into cold rolled 304 stainless steel plate and hot rolled stainless steel plate, which is the classification of 304 stainless steel plate. Especially the mechanical processing industry in the industry has very strict requirements for it. Different boards are suitable for different use environments. In view of this situation, in order to avoid wrong purchases, JIANGSU TISCO INDUSTRIAL CO.,LTD will introduce cold-rolled 304 stainless steel to you in detail. The difference between the plate and the hot rolled stainless steel plate is provided for your reference.

Introduction of hot rolled stainless steel plate:
Common ground:
First of all, whether it is cold-rolled 304 stainless steel plate or hot rolled stainless steel plate, it is produced in accordance with national standards, that is, the proportion of each element is the same. It is worth mentioning that 304 now has a new standard and an old standard. points, so the digital grades have also changed, specifically: S30408, TP304.

The content of its ingredients is listed below:
C (carbon)≤0.08, Si (silicon)≤1.0 Mn (manganese)≤2.0, Cr (chromium) 18.0～20.0, Ni (nickel) 8.0～10.5, S (sulfur)≤0.03, P (phosphorus)≤0.035, N (nitrogen)≤0.1.Among them, it mainly depends on the content of Cr (chromium) and Ni (nickel), so 304 stainless steel is often called 18/8 stainless steel, which refers to its corresponding content. When it comes to the old standard mentioned above, it reflects the effect. The old standard 304 is now sometimes called 302 stainless steel, and its content is one less chromium than the new standard 304, which is 17/8 stainless steel, so when buying Be sure to open the content of the material list provided by the merchant, and don’t be fooled.

The difference:
(1) Width Specifications
The thickness of cold-rolled 304 stainless steel plate is 0.3-3.0mm, the common size of the plate surface is 1000*2000mm, 1219*2438mm, 1500*3000mm, and the length can be set in coils;The thickness of the hot rolled stainless steel plate is 3.0-250mm, and the common size of the plate surface is 1500*6000mm, 1800*6000mm, 2000*6000mm, and special sizes can be customized.

(2) Appearance color
The surface of the cold-rolled 304 stainless steel plate is silver-white, relatively smooth and delicate to the touch;The surface of 304hot rolled stainless steel plate is dark, brown and rough, and it is not as smooth as a cold plate.

(3) Production process
304hot rolled stainless steel plate is produced according to the inherent process. The specific process can be concerned with JIANGSU TISCO INDUSTRIAL CO.,LTD. Its surface is relatively rough, the intergranular gap is large, and the pore density is large, so it has good ductility and is suitable for folding. Secondary processing such as bending and rolling;
The cold-rolled 304 stainless steel plate is made of hot rolled stainless steel plate by rolling twice. The pore spacing is very small, so it has strong hardness and strength, and the mechanical properties are very beneficial, but the ductility is not hot rolled stainless steel. Steel plate is good, so it is suitable for deep processing, exterior surface decoration, architectural decoration, machinery, coal chemical and other industries.

All in all, the use of 304 stainless steel plate is very common, especially food grade 304 stainless steel products can be seen everywhere in the kitchen, it is precisely because of its good mechanical and physical properties, as well as the temperature range of -196℃-800℃, Make 304 stainless steel material gradually become the mainstream product in the market. The above is about the introduction of hot rolled stainless steel plate.
