439 Stainless Steel Composition

Aisi type 439 also known as astm xm 8 is a ferritic stainless steel designed to resist corrosion in a variety of oxidizing environments from fresh water to boiling acids.

439 stainless steel composition. The chemical composition of grade 439 stainless steel is outlined in the following table. 439 uns s43035. Type 439 is an 18 chromium titanium stabilized ferritic stainless steel with corrosion resistance similar to that of 304 304l stainless steel. Introduction ati 439 a titanium stabilized 18 percent chromium alloy is also known as astm xm 8 and by the uns designation s43035 is a ferritic stainless steel designed to resist corrosion in a variety of oxidizing environments from fresh water to boiling acids.

This grade may be used in the annealed cold formed or as welded condition in applications where other stainless steels such as type 304 304l and type 430 are used. It may be used in either the annealed cold formed or as welded condition in many applications where other stainless steel alloys such as type 304 type 410 type 409 and type 430are used. Type 439 uns s43035 in coil form. The alloy resists intergranular corrosion and stress corrosion cracking.

Type 439 may also be used in many oxidizing environments where type 304 is considered adequate in terms of general corrosion resistance but is. Type 439 stainless steel is a ferritic stainless steel designed to resist corrosion in a variety of oxidizing environments from fresh water to boiling acids. Type 439 is a titanium stabilized 18 percent chromium alloy that may be used in many oxidizing environments where type 304 is considered adequate in terms of general corrosion resistance but is subject to chloride stress corrosion cracking.
