1.4016 vs 1.4301 Stainless Steel: Key Differences
What grade is 1.4016 equivalent to?
The primary equivalent for the EN material 1.4016 is the American AISI 430 stainless steel. Other equivalent designations include the German X6Cr17, the French Z8C17, the Swedish SS 2320, and the Japanese JIS SUS430. 1.4016 is a ferritic stainless steel known for its excellent corrosion resistance in atmospheric conditions and mild chemical environments. It can be processed into a variety of practical product forms, including sheet, coil, tube, bar, and wire.
What is material 1.4301 stainless steel?
Austenitic chromium-nickel stainless steel 1.4301, also known as AISI 304, BS 304S31, stainless steel 304, inox 304, or X5CrNi18-10, is a V2A stainless steel. Its characteristics include good corrosion resistance in natural environments (such as water (non-saltwater or non-chlorinated water) or humid environments) (PREN value 17.5 to 21.1). It is also very suitable for forging, rolling, and welding. AISI 304 (1.4301 / BS 304S31) is non-magnetic, exhibiting only very weak magnetism. It can be polished to a high degree (including a mirror finish), and can also be ground and brushed.

1.4016 vs 1.4301 Stainless Steel: Corrosion Resistance
1.4301 (AISI 304) offers significantly better corrosion resistance compared to 1.4016 (AISI 430) due to its higher chromium (18-20%) and nickel (8-10%) content, which enhances its ability to resist oxidation and corrosion in harsh environments, especially in chloride and acidic conditions. 1.4016, with only 16-18% chromium and no nickel, is more prone to corrosion in such environments, making it less suitable for applications like marine environments or chemical processing where higher resistance to pitting and crevice corrosion is required.
1.4016 vs 1.4301 Stainless Steel: Hardness
1.4016 (AISI 430) typically has a hardness of up to 92 HRB, which is higher than 1.4301 (AISI 304), which generally has a maximum hardness of 90 HRB. This is because 1.4016, being a ferritic stainless steel, tends to have a more brittle structure, contributing to its higher hardness, whereas 1.4301, an austenitic stainless steel, is more ductile and less prone to hardening. However, the hardness difference is relatively small and does not significantly affect their performance in most applications.
1.4016 vs 1.4301 Stainless Steel: Cost
Although 1.4016 contains no nickel, while 1.4301 has a nickel content of 8-10.5%, the price of 1.4016 (ferritic AISI 430) is typically 15-25% lower per ton than 1.4301 (austenitic AISI 304). However, due to differences in work hardening rates and surface treatment costs, the price difference narrows in thin gauges or precision-machined forms.
