Stainless steel grade 430 is a non-hardenable steel containing straight chromium, and belongs to the ferritic group of steels. It also has the ability to resist strong acid corrosion, and also because of the high chromium levels provides good resistance to oxidation.

Our 430 stainless steel sheet metal meets the criteria for both the #3 and #4 finish. It is not hardenable, but has high strength and is easily drawn, bent, formed and worked.

Stainless Steel Sheet/Plate 430 is normally used for architectural, machine, automotive, natural gas/petroluem/oil, thermal, and furniture applications.
Stainless steel as a whole is corrosion resistant however, different grades perform better than others.

The 430 grade also offers great strength and takes the knocks of a working kitchen well. 430 Stainless Steel Sheet #4 finish has a PVC film on one side to help protect against scratching during fabrication and installation. This grade also has excellent finishing qualities making it a great candidate for the appliance industry as dish washer … 430 is made up of 17% chromium and 0.12% carbon, 304 contains 18% chromium and 0.08% carbon.

CS 430 is a low-carbon plain chromium ferritic stainless steel. Type 430 is a ferritic stainless steel with corrosion resistance approaching that of 304/304L stainless steel. Manufacturers use 304 steel for creating kitchen sinks, countertops, food processing equipment, and other items regularly exposed to corrosive environments. This steel is known for its good corrosion resistance and formability, coupled with practical mechanical properties. Carbon: 0.12 max Manganese: 1.00 max Silicon: 1.00 max Chromium: 16.00-18.00 Nickel: 0.50 max Chemistry Typical .

440A is used in many production knives because of its edge retention, ease of resharpening, and corrosion resistance. The corrosion resistance of stainless steel 430 is close to those stainless steels that contain nickel. Differences between Type 304 … 430 stainless is notable for having a corrosion resistance similar to nickel stainless steels when exposed to atmospheric and mildly corrosive environments.

How to be sure that this grade or the other is suitable for your application? Stainless Steel - Grade 430 CS 430 Technical Data . STAINLESS STEEL GRADES & PERFORMANCES Different stainless steel qualities are used for door hardware, such as AISI 201, 304, 316 or 430. 430 stainless steel is a ferritic, straight chromium alloy melted as AOD. Type 430 (UNS S43000) in Coil Form.

Penn Stainless inventory now includes Alloy 430 (UNS S43000) in sheet, sheet coil, plate, round bar, processed flat bar and tubular products. When comparing these two types of steel, note that the 430 grade is magnetic while the 304 grade is not. Where cost is a larger factor than life span, 430 may be more suitable. This grade does not work harden rapidly and can be formed using both mild stretch forming, bending, or drawing operations. As a ferritic stainless steel, 430 stainless steel is categorized by its high chromium content.
The most common and expensive grade of steel is Type 304, which contains approximately 18 percent chromium and 8 percent nickel.
