In some cases, the low carbon Alloy SS Sheets 304L may show a lower corrosion rate than the higher carbon Alloy 304. The data for formic acid, sulfamic acid, and sodium hydroxide illustrate this. Otherwise, the Alloys SS Sheets 304, SS Sheets 304L, and SS Sheets 304H may be considered to perform equally in most corrosive environments. A notable exception is in environments sufficiently corrosive to cause intergranular corrosion of welds and heat-affected zones on susceptible alloys SS Sheets 304,SS Sheets 304L.

1) NO. 1 -After hot rolling, to do heat treatment, pickling or corresponding processing on products.
2)2D - Annealed and pickling finish, semi-matt silver-grey surface. D= Dull
3)2B - Skin passed finish, , 2D light rolling between highly polished rollers B= bright
4)BA- Bright heat treatment or bright annealed, the product are of high reflectance and gloss.
5)HL-Using appropriate abrasive to grind product continuously so as to make grinding grain in it.
6)8K-The product is continuous processed with 1000 # abrasive thus it is with high gloss and
Low and Elevated Temperature Properties
Typical short time tensile property data for low and elevated temperatures are shown below. At temperatures of 1000°F (538°C) or higher, creep and stress rupture become considerations. Typical creep and stress rupture data are also shown below.
