W.Nr.2.4819 alloy steel density：8.9g/cm3
W.Nr.2.4819 alloy steel Melting temperature range: 1325-1370 degree
W.Nr.2.4819 corrosion-resisting alloy steel application:
W.Nr.2.4819 has been widely used in chemical and petrochemical, such as element application chloride containing organic compounds in contact and catalytic system. This material is particularly suitable for high temperature, mixed with inorganic acid and organic acid impurities (such as formic acid and acetic acid), the use of seawater corrosion environment.
Other special applications:
The pulp and paper industry, such as cooking and bleaching solution container
The FGD system in the washing tower, heater, fan, wet steam
Equipment and components, work in the acidic gases in the environment
Reactor, acetic acid and acidic products
sulfuric acid condenser
methylene two phenyl isocyanate (MDI)
impure phosphoric acid production and processing.
W.Nr.2.4819 Processing and heat treatment:
W.Nr.2.4819 solid solution treatment temperature is in the range of 1100 - 1160 degree .
The method of cooling water quenching, thickness of less than 1.5mm material also can use rapid cooling. If the air cooling, it should be from 1000 degree to 600 degree cooling in 2 minutes.
In the process of heat treatment, must keep the workpiece cleaning.
