Steel Plate Specification:
Thickness:0.3mm-100mm,
Width:200-3000mm.
Application:409 Stainless Steels are especially useful for applications where oxidation or corrosion protection beyond the capacity of carbon steel and some coated steels is needed.
409 Stainless Steel Introduction
SS 409 contain a certain number of surface inclusions which are the normal result of titanium stabilization additions to improve the steel. Occasionally, rusting may occur
at these inclusion sites and lead to problems with cosmetic appearance. As a result, these steels are not suggested for applications where surface appearance is a factor. In cases where surface appearance is important, 400 stainless steels should be considered.
409 Stainless Steel Usage
Current applications include automotive and truck exhaust systems, including tubular manifolds; agricultural spreaders, gas turbine exhaust silencers, and heat exchangers.409 Stainless Steels are also useful for “difficult-to-form” hardware such as fuel filters.
