Ki diferans ki genyen ant 1.4303 vs 1.4301?

The main difference between 1.4303 and 1.4301 stainless steel lies in their nickel content and formability: 1.4303 (AISI 305) has a higher nickel percentage (10–13%) than 1.4301 (AISI 304), which provides better deep-drawing and cold-forming capabilities with lower work hardening, while 1.4301 offers slightly higher strength and is more widely used for Aplikasyon jeneral-bi.
