Stainless Steel - Type 304 or Type 301 - Why Does It Matter?

A common question is which stainless steel is right for my project, Type 304 or Type 301? While both alloys are stainless steel and very similar in content, there are some key differences, the percentages of chromium, nickel and carbon. Type 301 was developed to be a lower-cost alternative to Type 304.

Zinc Alloy vs Stainless Steel The Differences & Benefits

May 07, 2018 · Zinc is cheaper than chromium, and therefore, in general, zinc alloys are relatively less expensive than compared to stainless steel. Though more expensive, stainless steel is a strong, tough material noted for its corrosion resistance. Though some Zinc alloys can be very strong, overall stainless steel is stronger.
