Applications
304 stainless steel is the most widely used chrome-nickel stainless steel, as a widely used steel, has good corrosion resistance, heat resistance, low temperature strength and mechanical properties; Stamping, bending and other hot processing good, no heat treatment hardening phenomenon (use temperature -196℃ ~ 800℃). Corrosion resistance in the atmosphere, if it is an industrial atmosphere or heavily polluted areas, it needs to be cleaned in time to avoid corrosion.
Suitable for food processing, storage and transportation. It has good processability and weldability. Plate heat exchanger, bellows, household goods (1, 2 types of tableware, cabinets, indoor pipelines, water heaters, boilers, bathtub), auto parts (windshield wipers, mufflers, molding products), medical equipment, building materials, chemicals, food industry, agriculture, ship parts, etc. Among them, the content of 304 stainless steel is strictly controlled, which can also be called food-grade 304 stainless steel.
Differences between cold rolled and hot rolled 304 stainless steel
Difference one: different processing technology.
304 stainless steel cold rolled and hot rolled the biggest difference is that the processing process is different.
1. Cold rolling refers to the processing of 304 stainless steel plate at room temperature, through the roll pressure to make the plate thinner and achieve the required size and surface quality.
2. hot rolling is 304 stainless steel plate is heated to a certain temperature, and then through the roll pressure to make its deformation, and finally get the required size and surface quality.
Difference two: different mechanical properties.
There are also differences in the mechanical properties of cold rolled and hot rolled 304 stainless steel. 3.
3. The cold rolled 304 stainless steel sheet has higher hardness and strength, but lower plasticity and toughness.
4. hot rolled 304 stainless steel plate is relatively soft, with good plasticity and toughness, but lower hardness and strength.
Difference three: different surface quality.
The surface quality of cold rolled and hot rolled 304 stainless steel is also different.
5. The surface finish of cold rolled 304 stainless steel plate is higher and there are fewer surface defects and oxides.
6. The surface quality of the hot rolled 304 stainless steel sheet is relatively poor, and there are more surface defects and oxides.
7. However, the hot rolled 304 stainless steel sheet can be improved by subsequent surface treatment to improve its surface quality.
Summarize:
To summarize, the difference between cold rolled and hot rolled 304 stainless steel mainly lies in the three aspects of processing technology, mechanical properties and surface quality. When choosing 304 stainless steel plate, the suitable processing technology and plate type should be selected according to the specific needs and requirements of use.
