254SMO Stainless Steel Plate Description
254 SMO is a stainless steel originally used in seawater and other aggressive chloride environments. This grade includes a very high-end austenitic stainless steel; consisting primarily of 17.5 to 18.5 percent nickel, 19.5 and 20.5 percent chromium, 6 to 6.5 percent molybdenum, and. 18 to. 22 percent nitrogen. In this "super austenitic" chemistry, these specific levels of Cr, Ni, Mo and N give the 31254 impact toughness to resist cracking, pitting and crevice corrosion, and almost twice the strength of 300 series stainless steel.

Galvanized coils are our top choice for durability and
consistency.
The zinc layer
uniformity saves us time in post-processing, and your team's technical
support is
always
helpful.

We have been purchasing yulun galvanized steel coils for
the quality
has
consistently exceeded our expectations. The coating uniformity, corrosion
resistance, and
surface finish meet our strict standards, making them ideal for
construction.
