The major difference between 301 and 302 stainless steel is their composition. 301 contains 16-18% chromium, 6-8% nickel, and 0.03% sulfur, while 302 contains 17-19% chromium, 8-10% nickel, and 0.15% sulfur. Both grades also contain carbon in small amounts.
The differences in composition result in some very noticeable differences in their characteristics and performance. For example, 301 stainless steel has higher tensile strength than 302 (approximately 1/2 hard) but lower ductility than that 302 (approximately 1/4 hard). This means that it will be less prone to bending or breaking when exposed to pressure but more likely to deform if it is exposed to too much force or stress. Additionally, 301 has higher magnetism than 302, as well as greater work-hardening capabilities when cold-worked or heat treated.
