SUS836L

SUS836L Austenitic Stainless Steel
High corrosion resistant austenitic stainless steel

 

Characteristics of SUS836L:
SUS836L is a kind of austenitic stainless steel with relatively high corrosion resistance. It contains high nickel, chromium and molybdenum. As a result, it is a kind of economical steel. It is well-known for its extremely high corrosion resistance. It can maintain this superior performance even under the harsh environment of elevated temperature and seawater. To a certain extent, its corrosion resistance can be comparable with that of hastelloy and titanium. Due to its high content of chromium and molybdenum, the pitting and intergranular corrosion resistance of SUS836L in the environment of chloride ions with high concentration are very excellent. It is recommended to be used in marine engineering, seawater desalination plant, seawater heat exchanger, condenser and other marine environments as well as concentrated salt storage tanks, heated tanks, evaporators, salt-making equipment of salt conveyor line and so on. SUS836L is also equipped with the typical properties of austenitic stainless steels, such as high ductility, great toughness and good workability.

Weldability of SUS836L:
The welding of SUS836L is the same as that of the ordinary austenitic stainless steels. Manual arc welding, TIG welding and plasma welding can be used in this process. Preheating and heating are not necessary. Furthermore, the welding material used should be C series of hastelloy. 

 

Heat treatment of SUS836L:
1. Solution treatment: 1125~1175℃, water cooling
2. Stress relieving heat treatment: 450~550℃, air cooling

 

Applications of SUS836L:
SUS836L is suitable for the applications under the environments of marine, chloride ion with high concentration and salt with high concentration, etc..
1. Marine environment: marine engineering, seawater desalination plant, seawater heat exchanger, condenser, condenser tube;
2. Environment of chloride ion with high concentration: pulp and paper industry, a variety of bleaching equipment, scrubber;
3. Environment containing salt with high concentration: resin manufacturing apparatus, reaction vessel and piping of pharmaceuticals;
4. Chemical equipment: PC manufacturing equipment, bisphenol A manufacturing equipment, carbon black manufacturing equipment;
5. Medical equipment: centrifugal separator, reactor;
6. Food equipment: soy sauce fermentation tank, salt sweetener jug, sauce manufacturing equipment;
7. Salt-making equipment: concentrated brine storage tank, heated tank, evaporator, salt transmission line;
8. Environmental protection device: thermal power station flue gas desulfurization device.
