Are plain steel chimney liners ok?

I have recently moved into this home and one chimney has a thick steel liner. Non stainless 10 inch liner in a 24x24 brick inside chimney. This is very common in this area with larger capacity furnaces and stoves that use bigger sized flues. Im guessing these are ok to use but may require more frequent cleanings?

Thanks for any advice.
