Stainless steel bar is a very common material in stainless steel products, round steel, square steel, hexagonal steel, octagonal steel, flat steel collectively known as stainless steel bar. Stainless steel bar is widely used in hardware kitchenware, food, medical, electric power, petrochemical, building decoration, shipbuilding and other fields.
In the field of stainless steel bar, often people can not distinguish 303 and 304 stainless steel, what is the difference between the two?
1. Look at the surface: due to the sulfur content, the bright surface of 303 is a little dark, showing a dark, slightly worse brightness compared with 304, which has a high finish from the surface.
2. Machining performance: 303 good turning, easier processing, 303 stainless steel bar is more suitable for automatic lathes. 304 is a high strength alloy material, corrosion resistance, high temperature resistance, suitable for food, pipeline, medical treatment.
3. Material certification: When purchasing 303, 304 stainless steel bar, manufacturers can provide material certification to ensure the authenticity of raw materials.
4. Testing: 303 stainless steel bar and 304 stainless steel bar have roughly the same chemical composition, 303 sulfur content is higher than 304, so sulfur content testing can be done to determine the material.
