The difference between 316 stainless steel pipe and 316L stainless steel pipe(1)
The difference between 316 stainless steel pipe and 316L stainless steel pipe(1)
316L stainless steel pipe is a kind of pipe widely used in food hygiene equipment or fluid transportation. The appearance of the tube is a long annular hollow steel tube. Industrial equipment, metallurgical equipment, medical equipment, food and light industry transportation pipelines or mechanical parts will use 316L stainless steel pipes, but many customers will confuse 316L with 316. The following briefly introduces the difference between 316L stainless steel pipe and 316 stainless steel pipe:
Difference in product cost
316 L stainless steel has low carbon content and is easy to weld, so the price of 316 L stainless steel pipe is more expensive than that of 316 stainless steel pipe, but the difference is not big. In addition, 316 L stainless steel can also be called ultra-low carbon steel 316 stainless steel.
Differences in compressive strength of stainless steel pipes
The compressive strength of 316 stainless steel pipe is higher than that of 316 L stainless steel pipe. The compressive strength of 316 stainless steel pipe is higher than 520 MPa~(316 L) stainless steel pipe. The compressive strength of 316 stainless steel pipe only exceeds 480 Mpa. This is because carbon is a strong martensite generating element, which can significantly improve the compressive strength of stainless steel pipes.
Differences in specific applications
The cost difference between 316 L stainless steel and 316 stainless steel is not big, and the corrosion resistance and forgeability of 316 L stainless steel are significantly better than that of general 316 stainless steel. From the manufacturer's point of view, stainless steel processing plants are reluctant to manufacture because the requirements for general 316 stainless steel are very low. Therefore, most of the specific commodities in the sales market are low-carbon and environmentally friendly 316 L stainless steel. Generally, 316 stainless steel is rarely sold in the market unless there are special requirements.
