Corrosion resistance

The corrosion resistance of **4 stainless steel is better than that of **4 stainless steel.The **6 stainless

steel is also resistant to ocean and corrosive industrial atmosphere erosion.

Heat resistance

Under **1 ° C (***0 ° F) of use and at **7 ° C (***0 ° F) above, the continuous use of **6 stainless

steel(*6 cr*7ni*2mo2) has good oxidation resistance.At **7 ° C to **7 ° C (**0 ° F to ***5 ° F) range,

it is best not to use **6 stainless steel continuous, but outside the temperature range of continuous

use **6 stainless steel, the stainless steel has good heat resistance.The performance of **6L stainless

steel is better than that of **6 stainless steel, which can be used in the above temperature range.

Heat treatment

In *******0 ° C temperature range of annealing, and annealing quickly, and then rapidly cooling.**6

stainless steel cannot be hardened by heat treatment.

Weld

**6 stainless steel has good welding performance.All standard welding methods are available.The

filler rod or electrode of **6Cb, **6L or **9Cb stainless steel can be used for welding according to

the purpose.In order to obtain the best corrosion resistance, the welding section of **6 stainless

steel needs to be annealed after welding.If **6L stainless steel is used, no post-welding annealing

is required.

The main USES of **4 stainless steel capillary tube are heat exchangers for pulp and paper making

equipment, dyeing equipment, film washing equipment, pipes and materials for external use in

buildings in coastal areas.In ***3, it was also used in the field of solenoid valves, mainly for shells,

clamps, spheres, valve bodies,seats, nuts, stem and so on.Because **6 stainless steel corrosion
