Sell alloy 825 welding wire

CHEMICAL COMPOSITIONS

• Good resistance to corrosion in acids and alkalis and is most useful under reducing conditions.
• Outstanding resistance to caustic alkalis up to and including the molten state.
• Virtually immune to inter granular attack above **5C, chlorates must be kept to a minimum.
• In acid, alkaline and neutral salt solutions the material shows good resistance, but in oxidising salt solutions severe attack will occur.

• Resistant to all dry gases at room temperature and in dry chlorine and hydrogen chloride may be used in temperatures up to **0C.
• Resistance to mineral acids varies according to temperature and concentration and whether the solution is aerated or not. Corrosion resistance is better in de-aerated acid.

• Manufacture and handling of sodium hydroxide, particularly at temperature above **0C.
• Production of viscose rayon. Manufacture of soap.
• Analine hydrochloride production and in the chlorination of aliphatic hydrocarbons such as benzene, methane and ethane.

• Manufacture of vinyl chloride monomer.
• Storage and distribution systems for phenol - immunity from any for of attack ensures absolute product purity.
• Reactors and vessels in which fluorine is generated and reacted with hydrocarbons.
