Compared with the same model, it has better corrosion resistant properties which name is added L behind, for example:
【Difference between 304 and 304L】
304L stainless steel is superior corrosion resistance compared with 304 stainless steel, but 304L contains low carbon.
304 stainless steel has wide range of uses and good corrosion resistance, heat resistance, low temperature strength and mechanical properties; it also has good heat processing properties with no heat hardening such as pressing bending etc. (non-magnetic, temperature -196 ° C ~ 800 ° C)
304L has excellent inter-granular corrosion resistance after welding or eliminate stress. In the case without heat treatment, it also good corrosion resistance, (temperature -196 ° C-800 ° C )
【Difference between 1Cr18Ni9Ti and 0Cr18Ni9 (304) the difference between】
Carbon content of them is different, 1Cr18Ni9Ti is higher. They has the same Chromium, nickel content, as 18% and 9%, respectively.
In this case, because 0Cr18Ni9 has low carbon content, it has lower strength than 1Cr18Ni9Ti , better corrosion resistance than 1Cr18Ni9Ti. However, 1Cr18Ni9Ti contains titanium which has inter-granular corrosion resistance properties, it can increase inter-granular corrosion resistance properties after heat treatment.
【Difference between 304 and 316】
The corrosion resistance properties of 304 stainless steel is not as good as 316, and temperature requirements of them both can used.
If you do not consider the corrosion resistance properties of them, you can choose the economic costs of 304 which has low cost.
Corrosion resistance ranking from low to high
1cr18Ni9Ti, 304,304 L, 316,316 L, 317,317 L, 321
