Buying advice

When selecting a stainless steel grade, consider the environment (chloride exposure, acidity, temperature), required mechanical properties (strength, hardness, formability), and budget. 304 and 316 are versatile for most applications, while martensitic grades suit high wear needs. For extreme corrosion or strength, specialized alloys like 904L or 17-4 PH are warranted.
