Stainless Steel:

304, 304L: Both type are extremely popular in food and dairy industries and for use in pharmaceutical equipment. It is exceedingly useful in applications where good mechanical properties and corrosion resistance are essential. It is highly desirable for products such as instrumentation where non-magnetism is fundamental. These grades are available in a wide range of forms and finishes.

316, 316L: Type 316 and Type 316L find its greatest in the chemical, textile, paper, pharmaceutical and Photographic industries because of its excellent resistance to chemical corrosion, its also finds use where the combination of corrosion resistance and its extremely high strength at elevated temperatures is necessary.

321: Type 321 is used principally for application involving welding or sustained elevated temperature operations where reannealing is not practical. It is used extensively in the aircraft and missile industries for engine parts, heat exchanger, exhaust stacks, rocket engines, manifolds and etc.
