STAINLESS STEEL
Quality is Everything.
The stainless steel has a characteristic high corrosion resistance and temperature.
When distributed homogeneously the constitution Steel, Chrome, on contact with air to form a thin layer that protects the material from oxidation and corrosion from the environment. You can add other elements to further improve this mixture:
Known as Austenitic, this is a compound formed by alloys Iron + Chromium + nickel.
Its main features are:
• High resistance to corrosion;
• High durability;
• Non-magnetic;
• Cryogenic Applications, may be used in high and low temperatures due to its resistance to oxidation and softening at high temperatures;
• When heated above 600 ° C, the material AISI 304 is more who indicated steels containing low carbon as the 304L and 316L, due to its tendency to corrosion of the grain boundary;
• Weldable pro various processes.
The Ferritic alloys are formed by iron + chromium.
Its main features are:
• Present magnetic characteristics;
• Do not hardened by quenching (martensitic transformation);
• Can be drilled, cut, bent etc;
• With a high resistance to corrosion;
• Soldiers using special features;
• Attention to reheat the other temperatures: there grain refinement by thermal treatment.
The Martensitic alloys are composed mainly of Iron + Chromium + Carbon.
Its main features are:
• Present magnetic characteristics;
• When heat-treated have moderate resistance to corrosion;
• harden with heat treatment;
• Hard soldering process;
• Good resistance to solutions such as nitric acid, however, corrosive reducing solutions with sulfuric acid and hydrochloric acid.
• Fall in resistance with increasing quantity and elements as Carbon, Sulfur and Phosphorus.
