Whether you're an engineer designing food processing equipment or a procurement specialist sourcing for architectural applications, this article will clarify why 302 stainless steel is a trusted option. Explore our sa 240/a 240 uns stainless grades portfolio for related grades like sa 240/a 240 uns s21400, sa 240/a 240 uns s21600, sa 240/a 240 uns s21800, sa 240/a 240 uns s24000, sa 240/a 240 uns s30100, sa 240/a 240 uns s30103, and sa 240/a 240 uns s30153.
ASTM A240/ASME SA240 UNS S30200, commonly known as 302 stainless steel, is an austenitic stainless steel with 17.0-19.0% chromium, 8.0-10.0% nickel, and a maximum of 2.0% manganese. It is designed for applications requiring excellent corrosion resistance, good formability, and moderate strength, making it ideal for industries such as food processing, architectural, and general-purpose manufacturing. The lower carbon content (≤ 0.15%) compared to other grades enhances weldability, while maintaining good corrosion resistance in mild environments, similar to sa 240/a 240 uns s30100.
The ASTM A240/ASME SA240 UNS S30200 stainless steel plate offers better corrosion resistance than sa 240/a 240 uns s21400 and sa 240/a 240 uns s24000 due to its higher nickel content, though it is less corrosion-resistant than molybdenum-containing grades like sa 240/a 240 uns s21600. Its excellent formability and corrosion resistance make it a preferred choice for applications requiring aesthetic appeal and durability.
Key benefits of ASTM A240/ASME SA240 UNS S30200 stainless steel plate include:
Case Study: A food processing equipment manufacturer in India used sa 240/a 240 uns s30200 plates for conveyor components, achieving a 20% cost reduction compared to sa 240/a 240 uns s30400 while maintaining corrosion resistance and formability in mild environments.

ASTM A240/ASME SA240 UNS S30200offers excellent corrosion resistance in mild environments, such as indoor settings, food processing environments, or areas with low humidity and minimal exposure to corrosive agents. Its 17.0-19.0% chromium and 8.0-10.0% nickel content provide a robust protective oxide layer, making it suitable for applications like kitchen equipment and architectural cladding. It outperforms sa 240/a 240 uns s21400 and sa 240/a 240 uns s24000 in corrosion resistance, but is less resistant to pitting and crevice corrosion than molybdenum-containing grades like sa 240/a 240 uns s21600 or sa 240/a 240 uns s31603. For chloride-rich or acidic environments, grades like sa 240/a 240 uns s32550 are recommended.

The carbon content (≤ 0.15%) of ASTM A240/ASME SA240 UNS S30200 allows for good weldability, though it is slightly more prone to sensitization than low-carbon variants like sa 240/a 240 uns s30103 or sa 240/a 240 uns s30153. With proper welding techniques, such as TIG or MIG with low heat input and appropriate filler materials, it can be welded effectively to minimize intergranular corrosion. Compared to sa 240/a 240 uns s21800, UNS S30200 offers similar weldability but better corrosion resistance. For applications requiring superior weldability, sa 240/a 240 uns s30103 is a better choice.
