Material Characteristics:
The corrosion resistance of martensitic stainless steels is better than that of other martensitic stainless steels which can be quenched and hardened. [SCALE STEEL]In most media, the corrosion resistance of martensitic stainless steels is comparable to that of 316 type stainless steels.
② High strength.After heat treatment according to national standard specification, hardness ≥36HRC or ≥42HRC can be obtained.
③ It is easier to weld than other stainless steels that can be precipitated and hardened. It can be welded by traditional inert gas method.

Applications
633Stainless Steel is commonly used in applications up to 1000°F (537 ° C) where strength and good corrosion resistance are required, such as [SCALE STEEL]gas turbine compressor components (blades, plates, rotors and shafts), and similar components requiring high strength at room and moderate temperatures;Precision seals, couplings for semiconductor processing equipment and high vacuum systems;Aerospace applications requiring high strength edge welded bellows, etc.
