What is the diffrent Aluminized steel Type 1. stainless steel 409 430?
Alloy steel is a stainless steel. The differences between the two are the composition of the metal. Alloy steel is steel with usually less than 5% of other elements, like molybdenum, copper, chrome while stainless steel is a steel with at least 10-11% of chromium.
Stainless steel 400 Series—ferritic and martensitic chromium alloys Type 409—cheapest type; used for automobile exhausts; ferritic (iron/chromium only) Type 430—decorative, e.g., for automotive trim; ferritic. Good formability, but with reduced temperature and corrosion resistance. Today, almost all bulk metal materials that are referred to loosely as aluminium, are actually alloys. For example, the common aluminium foils are alloys of 92% to 99% aluminium. Aluminized steel Type 1: 1xx.x series are minimum 99% aluminium
