Surface finished of stainless steel
| Surface finish | Characteristics & Application |
| NO.1 |
Hot-rolled surface,annealed and pickled,can be used as cold-rolling material,industial tanks and chem i cal devices. |
| NO.2D |
Cold-rolled, an nealed and pick led with out skinpassing the dull prod ucts can be used as auto mo bile parts, build ing materrials and pipings. |
| NO.2B |
The surface brightness and flatness of NO.2B is better than NO.2D. Then through a special surface treament to improve its mechamical properties, N02B could nearly satisfy com pre hen sive uses. |
| NO.3 |
Polished with abra sive belt of grit #100#120,have bet ter bright ness with dis con tin u ous coarse stria, used as in ner and ex ter nal or na ments for building, elec tri cal ap pli anc es and kitchen uten sils etc. |
| NO.4 |
Polished with abrasive belt of grit #150-#180, have better brightness with discontinuous coarse stria, but thinner than NO.3, are used as bathtud building inner and external ornaments electrical appliances, kitchen utensils and food processing equipment etc. |

Features: 254 SMO is a high performance austenitic stainless steel. Its high alloying
elements content imparts excellent resistance to uniform, pitting and crevice corrosion,
and stress corrosion cracking. It was originally developed to withstand the corrosion of acids,
especially in the presence of halide ions, such as hydrochloric acid, hydrofluoric acid,
phosphoric acid, and sulphuric acid contaminated with chlorides. In certain environments it is an alternative to more expensive nickel alloys and titanium alloys.
Applications: Chemical processing equipment, pulp and paper industry bleaching equipment, desalination plant seawater piping, food and beverage industry, pharmaceuticals,
and hydrometallurgy.
Alloy 254 SMO is a very high end, molybdenum and nitrogen alloyed super austenitic stainless steel with low carbon content. It demonstrates outstanding resistance to pitting, crevice corrosion stress cracking, and corrosion fatigue uniform corrosion. Alloy 254 SMO is substantially stronger than the common austenitic grades, with strength nearly twice that of 300 series stainless steel. It is also characterized by high ductility and impact strength. With high levels of chromium, molybdenum, and nitrogen, Alloy 254 SMO is frequently used in high chloride environments, such as brackish water, seawater, pulp mill bleach plants, and other chloride process streams. In some applications it has even been found to be a more cost effective substitute for high nickel and titanium alloys.
Due to its high levels of molybdenum and nickel, Alloy 254 SMO is frequently used in high chloride environments. Examples of applications that call for the used of Alloy 254 SMO include:
