Feature

 

Good toughness / plastic nature /deformability;Be able to bend/ crimp/ fold at room temperature, good solderability T 800 Stable oxidation resistance; long-term use at T =- 40 -540 .

 

Good thermal conductivity / low swell factor, excellent resistance to corrosion; Its machinability inferior to the former one. T 750 Stable oxidation resistance

High level of ferrochrome, stainless, T = 800 -1200 During the intervals of 400 ,stainless steel is with the strongest antioxidant, at 310 is with the same or better anti-cyclic oxidation.

Ultra-pure iron ferrite stainless steel, good performance in mechanical properties / toughness / welding performance / antioxidant / anti-stress corrosion  particularly suitable for organic acid / oxidizing acid / alkali corrosion conditions; in chloride medium has good resistance pitting corrosion resistance; while in chloride / hydrogen sulfide / sulfuric acid / alkali-free corrosion, there is no cracking stress point.

Better performance in toughness and  cold eformability, T 30 , in  the weak corrosion medium, it has good corrosion resistance, T 700 , it shows sufficient strength / thermal stability / good flexibility.
