Type 439 is an 18% chromium, titanium stabilized ferritic stainless steel with corrosion resistance similar to that of 304/304L stainless steel. 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.

What is 439 stainless steel?
Type 439 is an 18% chromium, titanium stabilized ferritic stainless steel with corrosion resistance similar to that of 304/304L stainless steel. 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.
Is 439 stainless steel magnetic?
Some of the typical magnetic stainless steels include: Stainless steel grades 409, 430 and 439 also known as ferritic stainless steels. Stainless steel grades 410, 420 and 440 – martensitic stainless steels.
How many types of SS sheets are there?
Galvanized steel is available in two varieties: electro-galvanized sheets and hot-dipped metallic-coated sheets. The former is composed of cold rolled annealed steel.
How much is a sheet of stainless?
Type 316
| Stainless Steel Gauge Width and Length | Weight Lbs. per Sq. Ft. | Estimated Weight per Sheet |
|---|---|---|
| 7 ga. (.1874″) x 48 x 120 | 7.871 | 314.8 |
| 11 ga. (.120″) x 48 x 120 | 5.040 | 201.6 |
| 16 ga. (.060″) x 48 x 120 | 2.520 | 100.8 |
| 20 ga. (.036″) x 48 x 120 | 1.512 | 60.48 |
What is the difference between 304 and 430 stainless steel?
Notably, 304 contains between 8 – 10.5% nickel whereas 430 contains 0%. The inclusion of nickel in 304 makes the metal more corrosion resistant than 430 however it is an expensive element which is one of the main reasons for the difference in cost between the 2.
What is type 430 stainless steel?
Type 430 is a ferritic stainless steel with corrosion resistance approaching that of 304/304L stainless steel. This grade does not work harden rapidly and can be formed using both mild stretch forming, bending, or drawing operations.
How can you tell if something is stainless steel or aluminum?
Appearance. Another big difference between aluminum and steel can be found in the way each metal looks. With aluminum, you are going to usually notice a grey color along with a dull texture. On the other hand, stainless steel is relatively shiny, and it often has a tint that is more silver than grey.
What grades of stainless steel are non-magnetic?
There are three grades of martensitic stainless steel – 410, 420, and 440. Austenitic stainless steels – the majority of stainless steels falling into this category are non-magnetic due to high levels of austenite.
Is stainless steel a CRA?
Austenitic stainless steels (304, 321, 316 etc.) Martensitic, ferritic, precipitation hardened stainless steels.

What is the difference between 410 and 430 stainless?
These steels obtain maximum corrosion and heat resistance through hardening. However, grade 410 steels are less corrosion resistant than austenitic grades and grade 430 ferritic alloys containing 17% chromium. Smooth surface finish offers improved performance of steels.
